Page 1 INTRODUCTION

(

)

The Clinton Nuclear Station has supply air and return air ducts that

'(

provide ventilation for Safety Class I electrical equipment in the control building.

The ducts pass _through a switchgear room near column row 122V at the 781'-0" elevation in the auxiliary building.

The ventilation air provides for cooling the equipment essential for safe shutdown.

A second ventilation duct system provides cooling air for the switchgear room.

Therefore, in the event of a fire in the switchgear room, both systems could be disabled by this single fire.

To eliminate this possibility, Transco undertook a program to develop an insulation system for the supply and return air ducts passing through the switchgear room.

This system was to have the capability of experiencing a 3-hour fire (as defined by ASTM-E119) without allowing the air to undergo more than a 12 deg. F rise (from 73 deg. F entering to 85 deg. F exiting) as it passed through the ductwork in the switchgear room.

The system developed, termed " FLAME GUARD" by Transco, combines high-temperature insulation capable of withstanding operating

. temperatures to 2300 deg. F (Cer-Wool, by CE Refractories) with high-thermal-performance insulation (Microtherm, by Micropore International) in a sandwich construction which also contains protective stainless steel facings and stainless steel vapor barriers. Proceeding from the fire-side of the FLAME GUARD system,

[~N the construction is as follows (see Figure 1):

outer lagging of

\\_)

24 ga. stainless steel; (1) layer of 2-inch thick 8 lb/cu.ft. Cer-Wool; (7) layers of 1/2-inch thick Microtherm; 0.002-inch thick stainless steel foil vapor barrier; (1) layer of 1/2-inch thick Microtherm.

Although the FLAME GUARD system can be applied to other fire protection situations, the particular configuration described here is unique to the Clinton project outlined above.

For example, the ducts to be treated are approximately 38 feet in length; because a 12 deg. F air temperature rise applies, longer ducts would require more insulation while shorter would require less thickness.

Another aspect of the problem addressed was the extent of insulation required on the steel support structures for the ductwork.

Both calculations and testing indicate 4'-6" of the support steel (from the ductwork) must receive FLAME GUARD.

This report describes the developmental analyses and testing performed by Transco to determine the proper configuration for FLAME GUARD and provides support for its capability to meet the design requirements outlined above.

Page 3 PRELIMINARY MATERIAL SELECTION 7

Transco contacted several companies which eith~r manufacture e

insulation products or are familiar with such products and solicited their recommendations for materials which (a) proven fire-environment capabilities and (b) which was both thin and light in weight.

These companies included:

Owens-Corning Johns-Manville Carborundum Babcock & Wilcox Fiberfrax Combustion Engineering W.

R.

Grace Co.

Micropore International TSI, Incorporated Portland Cement Association, Construction Technologies Lab.

These companies' unanimous recommendation'was that either alumina silica blanket or subliming materials be investigated by Transco.

Subliming materials are frequently applied in such areas as beam and cable tray coatings. When these materials.are exposed to flame or high temperatures, they sublime (pass directly from the solid to fS vapor state).

One product, Thermalog by TSI, Inc., sublimes near

. w) 600 deg.

F.

(

However, Transco found that subliming materials generally had relatively high thermal conductivities, high density, and may also suffer from product inconsistency due to the mixing process required.

This line of products was therefore discarded as a possible material for FLAME GUARD.

Further study of alumina silicate blanket materials showed them to be non_ combustible, capable of withstanding temperatures of 2300 deg.

F, light (3-8 lb/cu.ft.), and to have relatively low thermal i

conductivities and neglible water absorption and shrinkage E

characteristics.

This material was therefore selected as one primary component of the FLAME GUARD system.

Specifically, 8 lb/cu.ft. density Cer-Wool by CE Refractories was selected.

In the interest of minimizing interference problems with installation of the insulation system, Transco looked for a material with a very low thermal conductivity vis-a-vis Cer-Wool.

The objective was to minimize the total insulation thickness by using

---the Cer-Wool to reduce the temperatures to such levels that better insulating materials could be used behind the Cer-Wool; in particular, Microtherm by Micropore International.

l L

TRANSCO INC.

Page 4 As long as Cer-Wool of sufficient thickness is used on the fire-side of the combination to reduce the Microtherm temperature to 1700 deg.

F or less, Microtherm properties are well suited for the present

~

(_)g application.

(The physical properties of Microtherm are illustrated on the following 4 pages.)

Also, the potential advantage to be gained by using a Cer-Wool /Microtherm combination in lieu of all Cer-Wool, in terms of reduce'd total thickness, can be seen from Figure 2 showing a comparison of thermal conductivities.

In summary, Transco's studies of suitable materials to be used in the FLAME GUARD system resulted in the selection of a combination of Cer-Wool (" hot" side) and Microtherm (" cold" side).

Analyses and testing was then required to determine the appropriate thicknesses to ensure no more than a 12 deg. F air temperature rise in the (approx.) 38-feet long supply and return ducts when exposed to the ASTM-E119 3-hour fire test.

Although mineral wool thermal conductivities are considerably greater than Microtherm's, some published literature reviewed by Transco indicated that its " thermal diffusivity" was quite low.

(The importance of this will be seen in the discussions presented below.)

-Because of mineral wool's low cost, Transco therefore included testing of mineral wool to determine if it could be used in

" combination with Cer-Wool.

ANALYSES AND TESTING -- PROCEDURES AND RESULTS G

A.

Steady-State The problem of determining appropriate insulation thicknesses for the FLAME GUARD system was first approached from a steady-state viewpoint.

TRANSCO INC. Page 13 interferences in the actual installation. Its primary limitations are (a) the assumption of no variation in thermal conductivity with /~T temperature and (b) the assumption of no thermal capacitance (heat (_/ storage capability) of the insulation. Therefore, Transco had to undertake a more realistic transient analysis procedure in which these limiting assumptions c,o,uld be relaxed. In the hope of minimizing analysis time, these assumptions were addressed individually to see if a successful analytical model would result. B. Transient Analysis -- Thermal Capacitance Effects of Insulation Cer-Wool properties (8 lb/cu.ft.) were selected to determine the adequacy of a transient analytical model including the effects of the insulation's thermal capacitance. Actual lab testing on a nominal thickness of 14-inches of Cer-Wool was conducted to (a) provide information on a suitable " time / temperature averaged" thermal conductivity to use in the analytical model and (b) establish a baseline for comparison form analytical results. 4 Test TTR-30N (note: all TTR tests referred to in this report are included at the end of the report) discusses in detail the . analytical procedure used to evaluate transient temperatures inside the insulation. A standard "Schmidt" approach was used, as referenced in many heat transfer texts. Referring to Figure XII in TTR-30N, it is seen that, except for the fN end points (faces of the insulation), the transient analysis which (_) does not account for variations in thermal conductivity with temperature does not adequately represent the actual situation. For example, at location #6 (about 5.4 inches from the hot face) the measured temperature exceeds the calculated temperature by nearly 700 deg. F. C.

A convection coefficient of h=5 Btu /hr-sq. f t.-F and constant air tempera-ture of t(air)=73 F was assumed for the calcu-lations. 3.

Selection of Insulation Thicknesses Figure 6 illustrates the results of the most comprehensive model developed by Transco in the analytical area. These results were used to select tentative final insulation thicknesses to be confirmed as adequate by actual test results. (v)

TRANSCO INC. Page 17 i A conservative criterion of allowing no temperature increase of the duct wall (adjacent to the air flow) was used to select the / insulation thickness. Based on this, and referring to Figure 6, it \\s is seen that about 5-inches of Microtherm is sufficient. Remembering, however, that (standard) Microtherm cannot be subjected to more than 1700 deg. F, the problem of applying an appropriate thickness of Cer-Wool on the fire-side (hot face) was still unsolved. In order to determine how much the Microtherm thickness could be reduced and, simultaneously, how much Cer-Wool must replace this amount of Microtherm, the following criterion was applied: for the transient numerical model to remain valid, it is necessary that the following relationship be satisfied: [km/(rho, cpy(dx))) ] Micro. [kc/@ho cp, (dxI))]Cer-Wool ....Eq. (15) = From Eq. (15), the relationship between the thickness of Microtherm dx to be replaced by an equivalent thickness of Cer_ Wool dxe, can be expressed as: d x, = [ ( ke /k, ) ( rho,cp,, / rho cpc ) ] dx, ....Eq. (16) e (']/ Using tae appropriate values for the physical parameters, the x-relationship between equivalent thicknesses of Microtherm and Cer-Wool is: dxe% 2.65 (dx%) ....Eq. (17) Referring to Figure 6, it is seen that if approximately 1-inch of Microtherm is replaced on the hot side, the maximum temperature at the Cer-Wool /Microtherm interface will be about 1700 deg. F. According to Eq. (17), this requires about 2.65-inches of Cer-Wool to replace the 1-inch of Microtherm. Transco chose, for practical reasons, to use 2-inches of Cer-Wool for testing. Therefore, the final FLAME GUARD configuration (regarding insulation types and thicknesses) became 2-inches Cer-Wool /4-inches Microtherm, as illustrated in Figure 1, contingent upon tests showing its adequacy. E. Testing and Model Validation Test TTR-34N presents the measured results for the final FLAME GUARD configuration. (Note that the test included the exterior stainless O

TRANSCO INC. Page 18 steel lagging and vapor barrier which is part of the actual FLAME GUARD system--however, these components are not expected to have ) significant impact on the comparison of measurements with model s/ results.) Figure IV of TTR-34N shows the relevant data for evaluating Transco's final proposed configuration for the Clinton ventilating ducts as well as for evaluating the adequacy of the model used in its preliminary selection. The test data shows that, at the end of the 3-hour fire test period, (a) the interface temperature between the Cer-Wool and Microtherm is about 1700 F and (b) neglible temperature rise is experienced at the cold side of the Microtherm (i.e., adjacent to the duct wall); these are precisely as predicted by_the analytical model which includes both thermal capacitance and variable thermal conductivity of the insulation. Figure 7 shows a final comparison of predicted and measured results. It compares the 3-hour temperature profile curve of Fig. 6 with the TTR-34N results, shifted in accordance with the " thickness equivalency" relationship discussed above. The model results and measurements compare quite favorably. F. Problem of Steel Duct Support Structures Test TTR-31N addresses both the analytical and testing aspects of the necessary extent of application of FLAME GUARD to the duct ()} support steel. In summary, the results show about 4'-6" of steel C c (measured from the duct) must be treated to avoid heat transfer to the duct and air. G. Alternative System Evaluation -- Mineral Wool / Foils During its developmental program, Transco encountered two potentially cost-and/or space-saving aspects of insulation systems that seemed worth investigating. The first was the published fact that mineral wool had a very low thermal diffusivity, which in the final analytical model was the governing factor for insulation thickness. The second was that foils used between layers of insulation might provide better insulation characteristics than the same total insulation thickness without the foils. No analytical approach was used to investigate these possibilities, ~ however testing was conducted to determine their effects. Regarding the use of mineral wool, testing showed (TTR-32N) that it was not suitable due to the great thickness required. The foil concept did, however, indicate the possibility of reducing the total thickness. TTR-33N therefore addressed the foil concept with the Cer-Wool product. However, unlike the case for mineral wool, the foil did not seem to have such a space-saving potential. O i

CONCLUSION s This program of analysis and testing was undertaken by Transco to develop a practical fire-protection insulation system for the ventilating ducts at the Clinton station which would limit the temperature rise in the air to 12 deg. F when exposed to a 3-hour ASTM-E119 fire test. The resulting system was termed FLAME GUARD by Transco. Both analytical results and actual tests show FLAME GUARD to meet the design requirements at Clinton. The FLAME GUARD insulation must be applied both to the ductwork and about 4'-6" of all steel duct supports. Typical installation details and scope are illustrated on Transco Dwg. Nos.

TRANSCO I N C. TEST REPORT No. : TTR-30N LJ s 1. INTRODUCTION The Schmidt calculational technique has been used to predict the temperature response of a wall of eight (8) pound per cubic foot density Cer-wool to a three (3) hour fire. The temperature of the fire being defined by ASTM E119. The Schmidt method is ideal for one dimensional unsteady state problems with varying boundary conditions. t ~ The Schmidt method can be either a graphical or computer technique. The wall section of interest is divided into equal width segments. Temperature plots are then made on the assump-tion that the temperature at a point one inch in from the front face (or one_ division) must equal the average of the front face temperature, and the temperature two inches in from the front face: The temperature three inches in from the front face must equal the average of the temperature two inches in and four inches in from the front face: etc. This is a simplified explanation. For a complete explanation, a heat transfer text may be consulted. After a temperature versus thickness plot is made, the total wall thickness'is'obtained by solving the / following equation: V] t -t =c L2p/2k o f p Where: t -t = The time increments between temperature averages, o f In this case, ten minutes, or 10/60 hours. = The specific heat of the material, in BTU /Lb *F. cp I k = Thermal Conductivity in BTU /Hr-Ft *F. L = Distance between anes, in feet. p = Density in Lbs/Ft n = Number of wall increments (discussed in the following paragraphs). A table was made to predict the thickness of Cer-wool required to totally isolate a steel surface from the af fects of a three (3) hour fire. The table is in Appendix I. Each horizontal row of the table is the predicted temperature profile in that ten minute time increment. Each column represents a plane L feet thick spaced n~. feet from the front face. The actual dimension L being determined by the above equation. p To weight the thermal conductivity and specific heat by the time V averaged temperature, all temperatures were added in each column, and the total number of time increments in each column were noted.

TRANSCO I N C. TEST REPORT No. : TTR-30N _q I ms The total temperature,'in all the columns divided by the total number of time increments-yield a time weighted temperature in this case of 550.4*F. This temperature was then used to deter-mine thermal conductivity, and specific heat values. Subs titu-ting the values of specific heat and thermal conductivity in the Schmidt equation (above) yielded a distance between planes of 0.9214 inches. The Schmidt calculation in Appendix I indicated that 12.9 (14 x 0.9214) inches of Cer-wool will thermally. isolate a body from the affects of a three hour fire. The cold face should see a two degree temperature rise at the end of the three hours. The purpose of this test is to validate the calculational tech-nique. 2. TEST APPARATUS The test assembly was mounted on the Construction Technologies Laboratories gas fired pilot furnace. The test assembly consisted of a horizontal 24 gage stainless plate laid over the furnace opening. The plate was reinforced by 3 x 3 x 1/4" angles spanning the furnace opening. The furnace opening is about 30 [ '{. inches square (See figure I). v i On top of the plate, seven (7) layers of two (2) inch thick .Cer-wool were stacked. The actual thickness varied between 1-3/4 and 2 inches. The layers were 36 inches square. Beginning at the steel plate, each interface had three (3) thermocouples mounted in it; one at the center, and two on quarter points (See Figures IV and V). I-The test assembly was completed with three two-inch thick peripheral wraps of Cer-wool and a 24 gage stainless steel plate mounted on top of the assembly. Figures II and III show the nearly completed test assembly, less top thermocouples. Thermocouples were later placed on the top of the cover plate. No thermocouples were placed between the bottom of the steel plate, and the top of the first layer of Cer-wool. -The furnace is instrumented normally for 24 thermocouples. To record the temperature on the bottom surface of the steel plate would have required an additional three thermocouples over the furnace's standard 24. Bricks were placed on the periphery of the top cover to minimize air spaces between the plate and the insulation. Figures IV and V show the completed assembly. Note the steel weights placed on - (} the thermocouples to assure metal-to-metal contact between the \\- thermocouples and the plate. w

TRANSCO I N C. TEST REPORT No.: TTR-30N /% J The furnace is a gas fired, negative draft furnace capable of producing a temperature / time curve in accordance with ASTM E-119. ~ Fluc gas is. inducted from the bottom of the furnace to the building chimney by an induced draft fan, located below the floor. The fur-nace had'four.(4) burners, one on each wall. The burner plane is located approximately 30 inches below the test assembly bottom plate. The thermocouples are connected to a computer in the control room. 3. TEST RESULTS The test results are shown in Figures X, XI, and XII. Figures X, XI, and XII are the measured and calculated temperature profile in a 14 increment (14 x 0.9214 - 12.9 inches) thick wall of Cer-wool, at one hour, two hours, and three_ hours into the fire. In reviewing the three curves-the followin,g three points are obvious: 1. The slopes of the curves, dT/dL for the measured and the cal-culated are approximately equal on each graph. 2. The asymptotic approach to room temperature of the measured and calculated are approximately identical in regard to slope. The calculated temperature curve lags the measured by approxi-l,_) mately 1"-1 " of material thickness, in the intermediate tem-V peratures. 3. The temperature profile in the intermediate temperatures (at the midpoint of the wall) are on the order of 400, 600, and 0 700 F difference between the measured and the calculated tem-peratures. The calculation was to determine the thickness required to assure the three-hour fire did not reach the cold facc. The calculation is based on the hot face _and cold face temperatures being known; and the thermal coefficients being determined by time and temperature weighting of the thermal properties over the entire three-hour fire. The hot face tem-perature is 19250F, and the desired cold face temperature is 750F. Due to the weighting, the predicted value by the Schmidt calculational technique should be most accurate at the three (3) hour point; and at the indicated cold face temperature. Comparing the two asymptotes of the calculated and the measured, on the three-hour graph, Figure XII, at the cold face, the method seems accurate.

TRANSCO I N C. TEST REPORT No.: TTR-30N /T ' l'- / Specifically, the calculational technique predicted at 12.9 inches from the hot face, the temperature would rise approximately 2*F, assuming negligible resistance beyond the 12.9 inches (14 spaces times 0.9214 inches / space). Due to manufac-turing tolerances, the Cer-wool piles of seven layers had a actual dimension of between 12.5 and 13 inches thick. The back face rose 2*F at the end of the three hour test. This is exactly the temperature the Schnidq technique predicted. When it is considered that there is a' front face temperature of 1925'F, the Schmidt calculational technique seems remarkably accurate. At intermediate temperatures, however, the accuracy falls off significantly. ( THICKNESS ERROR IN PREDICTING THE 100*F THICKNESS, AND 1000*F l THICKNESS To quantify the accuracy of the calculational technique, a j defined temperature may be chosen to compare the thickness pre-dicted by the calculation, and the thickness actually measured. The thickness required to provide a 75'F temperature cannot be read from the graphs with any degree of accuracy, because the temperature line is nearly horizontal at this point. Choose the 100*F as the temperature point to compare the thickness - (~") predicted with the thickness of material measured. By the (_ / calculated curve of Figure XII, at the end of three hours at (10.5 spaces x 0.9214 inches / space =) 9.67 inches into the pile, the temperature should be 100*F. At 12.1 inches times 12.75/14, or 11 inches into the pile, a 100*F temperature was measured, r The 0.9214 multiplier on the calculated thickness is the actual L in the Schmidt calculation. Fortunately, the 12.75/14 inches multiplier for the actual pile height is 0.910. Hence both thickness multipliers are almost the same. Using an error equation for equal temperature thickness of: 100 (calculated thickness-measured thickness)/ Measured thickness = percent of thickness error. The error in the Schmidt calculational technique when used to predict the thickness at the intermediate temperature of 100*F three hours into the fire is: 100(9.67-11)/11 = - 13% \\ ,t t %j

T R A N S C O - I N C. TEST REPORT No.: TTR-30N O-V 4 Using the same equation ~t"the 100*F point for the two and one hour temperature profiles, the error is -14 percent, and -17 percent respectively. However, at the 1000'F point for the three hour curve, the error is on the order of 55 percent. The raw data recorded by Construction Technologies Laboratory, Fire Research Department is Appendix II, available upon request from Transco Inc. 4. CONCLUSIONS The Schmidt calculational technique is accurate for Cer-wool when used to predict the thickness and temperature of a cold face for a one dimensional body experiencing a well defined' temperature transient. However, the thermal coefficients must be weighted by time and temperature. The Schmidt calculational technique has reduced accuracy at temperatures and thicknesses between the hot face and the cold face. i (S 3 j (,,/ Approximately 13 inches of 81b/Ft Cer-wool will isolate a steel member from the effects of a three (3) hour ASTM fire. h. k v

TRANSCOINC. TEST REPORT No.: TTR-31N }.- 'y/ s 1. INTRODUCTION A Schmidt calculation was performed to predict the amount of insu-lation necessary to isolate a steel plate from the effects of a three (3)' hour fire, as defined by ASTM E-119. This calculation formed the basis for TTR-30N. This calculation has been modified to predict the length of insulated support steel required to iso-late a steel fabrication from the effects of a three-hour fire. The Schmidt calculation for an infinite wall assumes heat transfer is in one direction only, perpendicular to the wall. The front face -is'at some temperature that may vary with time. It is assumed there are no edge losses in the infinite wall. The Schmidt method predicted approximately 5'-5" of insulated steel would be required to isolate a steel member from the effects of a. three (3) hour ftre. See TTR-30N for more background on the Schmidt method. 2. TEST' ASSEMBLY The test apparatus consisted of the Transco'2000 F oven, a 2" x 1%" x k" thick eight (8) foot long carbon steel angle, wrapped with Cer-wool, 'v and an oven face plate made from stainless steel. l The steel oven cover had a-three (3) inch square hole cut in the cen- [ ter of the plate. The angle iron was then placed horizontally with j approximately one foot of the member extending into the oven cavity. L-The oven's internal dimensions measure 10" wide by 8" high by 12" {' deep. The oven's internals are shown in Figure 1. Oven insulation consists of six (6) inches of calcium silicate. The beam was then instrumented with two (2) thermocouples every one foot, beginning at the face of the oven and working out from the oven. The angle iron,was then wrapped with Cer-wool as shown in Figures II and III. The first two (2) feet of angle iron had approximately eight (8) inches of insulation. The second two (2) feet had approxi-mately six (6) inches of insulation. The balance of the angle had approximately four (4) inches of insulation. The thermocouples are connected to a gang switch. Output voltages are read by a Fluke 2100A Digital thermometer. Oven temperature is controlled by a Leeds & Northrup Electromax controller. The con-troller holds the temperature setpoint to +/- 100F at 19250F. The oven's outside dimensions are approximately 25" x 25" x 19" deep. Figures II and III show the completed test assembly.

T R A N S C O I N C. TEST REPORT No.: TTR-31N ..Q: N) .3. TEST PROCEDURE At time zero, the oven was at 102 F. The switch was turned on and the; oven controller was set to-19250F. Oven temperature readings were taken every five (5) minutes. All thermocouples were read every fifteen (15) minutes.. The purpose of taking readings of the oven temperature every five l (5) minutes was to determine the rate of rise in oven temperature and compare it with the ASTM E-119 curve for a three (3) hour fire. ~Eighty (80) minutes into the. test it was noted the oven temperature E 'was reading-19450F, even though the controller was set for 1925 F. The controller was then set down to 1830 F to more closely control the oven temperature to the actual temperature of 19250F. Ninety f90) minutes into the test it was noted the oven was hunting excessively at the setpoint. The door (which may'be seen in the left of Figure III) was closed. The oven cycling decreased. Thirty minutes into the test-it.was noted excess heat was coming from the steel face plate. Figure IV shows the Cer-wool, steel face plate interface at the start of the test. The plate was s/- warping causing excess heat loss at-the oven / plate interface. A loose blanket of marinite was made and placed over the top of the junction. The blanket is shown in Figure V. Figure VI shows loose fiberglass packed below the junction to shield the electrical controller from the effects of the heat leaking from the junction. Figure VII is a closeup of the junction (same view as Figure V). 4. TEST RESULTS The results are given in Figure VIII. Figure VIII is the tempera-ture at various distances from the oven face. The right hand side of Figure VIII includes an expanded scale to more closely see the asymptotic approach to room temperature of the temperature profile. The calculated temperature profile was based on a room temperature of 750F, and the room was actually close to 700F. Consequently, 50F was subtracted from the original calculated curve to form the curve that closely levels off at 700F. The five (5) degree dif-ferential does not significantly affect the calculated temperatures over'1500F. In Figure VIII the calculated curve always predicts a higher tempera-ture proffle, than was actually experienced. This could be the tech-nique, or perhaps the heat loss at the front oven face / insulation interface. L/

i -x_/ b -The heat loss at the insulation / oven front interface is a plausible ex-planation. In Figure VIII the thermocouples at the interface are approximately 300 F below the oven temperature. In dismantling the assembly, it was noted the interface thermocouples were located ap-proximately %" to 3/4" out from the oven. As the insulation was not tightly wrapped around the angle iron, and the opening in the plate front face was three (3) inches square, the thermocouples were al-most."seeing" the inside of the oven. Because the thermocouples were reading approximately 3000F less than the oven, it appears the interface was experiencing excessive heat loss. The calculation indicated that 5'-5" is sufficient to isolate the s-steel _from the effects of.the three-hour fire. Approximately 4'-6" was determined by experiment. Using the measured as a basis, the 's calculated length was in error by plus 20, percent of the meas,ured. Perhaps if the oven interface had been better sealed, the difference would have been significantly less. Figure IX is a-comparison between the.Transco oven temperature rise and that required'by ASTM E-119.- For experimental uses, the'Transco oven temperature rise closely approaches that of the ASTM E-119 three (3) hour temperature profile. .( ) s v ~ To verify the two temperature profiles were close to each other, the total area under the two curves was determined, in degree-minutes. For the ASTM E-119 the area determined was 302,825 degree, minutes. The Transco oven had a measured area of 291,435 degree-minutes. The Transco area is within 96 percent of the ASTM E-119 area. By the area being within five percent of the ASTM E-119 temperature and time curve, the oven's response neets the requirements of ASTM E-119. 3 S. CONCLUSIONS The Transco oven is qualified to reproduce the ASTM E-119 temperature / s time curve within acceptable tclerances, for a three (3) hour duration. To prevent a three (3) hour fire from conducting heat down the support-steel to the item being supported, a minimum of 4'-6" of steel should be insulated. The steel.hould be insulated to such thickness so as to prevent any heat gain iro n the fire directly through the insulation to the steel. I

TRANSCO I N C. 1EST REPORT No.: TTR-31N ESTIMATE OF LENGTH OF STEEL REQUIRED TO BE INSULATED, FROM DUCT, TO PREVENT STEEL FROM liEATING DUCT The Schmidt Analysis done for the Cer-wool is based on an infinite plane, i.e., there are no edge losses. If the steel is insulated so that the fire can only "see" bare steel a certain distance away from the ducc, then the insulated steel will be the same as an infinite plane with a high tem-perature (the portion cf steel seeing the flame) front face. Only the con-stants in the Schmidt calculation will change. The constants being for steel, instead of Cer-wool By the Schmidt equation: L = 2k (dT)/c p p Where: L = Spacing between planes, feet k = Thermal Conductivity, BTUll/Ft. -,F dT = Time increment between averages, lirs. c = Specific Ileat, BTU /Lb. 0F h= Density,Lbs./Ft.3 '_ N n = Number of insulation spaces, no dimension In reviewing the Schmidt Table, for all practical purposes we can assume we have 14 spaces with a temperature rise of 20F, By TTR-30N, the average temperature for 14 spaces will be 550.40F wheres k = 28 BTull/Ft. 0F p = 490 Lb./Ft.3 i n = 14 .13 BTU /Lb. - F c = Substituting: L = (2 x 28)(10/60)/(0.13 x 490)b = 0.38278 Ft. = 4.5934 inches nb = (14)(4.5934 inches) = 64.30 inches = 5'-5" ,m x_ f

T R A N S C O I N C. TEST REPORT No.: TTR-32N L l- ,_J s 1. INTRODUCTION Thermal Diffusivity is defined as: a = k/pc t Where: a = Thermal Diffusivity, in Ft.2/Hr. k = Thermal Conductivit in BTUH/Ft. - F p = Density in Lbs./Ft. c = Specific lleat, in BTU /Lb. - F Thermal diffusivity is a measure of the response of an insulation to a temperature transient. The lower the thermal diffusivity, the less. rapidly a material responds to a thermal transient. Because conductivity and specific heat vary with temperature, thermal dif-fusivity varies with temperature. Generally diffusivity increases with temperature. In TTR-30N Cer-wool thermal diff,usivity was calculated to be 0.0176 ft.2/hr., at a mean temperature of 550 F. TTR-30N predicted a 13-inch } . thickness of Cer-wool was needed to thermally isolate a ' steel member. J The purpose of the test was to find a material or combination of ma-terials that would isolate a steel member from the effects of a three (3) hour fire, and would be less than 13 inches in thickness. In Thermal Insulation, by Malloy, 1968, it was noted that mineral wool had a thermal diffusivity of between 0.01 and 0.026. In one case a diffusivity of 0.012 was reported. In an attempt to locate a material that had a lower thermal diffusivity, it was decided to the temperature response of 8 lb./ft.3 density mineral wool. test Literature reviews also indicated that highly reflective foil placed between insulation layers increased the effectiveness of the insula-tion. The foil introduces a thermal discontinuity which has resulted in a reduced heat transfer. 2. TEST APPARATUS -The test apparatus consisted of the Transco test oven at Streator, Illinois,.with associated instrumentation as detailed in TTR-31N. The. oven was placed on its back. A 24-gauge stainless steel plate 24 inches square was placed on the front face of the oven. As mineral wool has a temperature limit of <~

I T R A N S C O I N C. . TEST REPORT No.: TTR-32N p 1200F,atwo(2)inchthickCer-woollayer(temperaturelimit 0 0 2300 F) was placed on the plate. Then five layers of mineral wool, each two (2) inches thick were stacked on the plate. All layers were approximately 24 inches square. A stainless steel plate was then placed on the top of the assembly. Three thermocouples were placed between each layer, one at the center and two on a common 45 line on each side of the center. Due to a mixup in the test briefing, the two thermocouples on the i 450 line were placed outside of the projected area of the heated portion of the oven. Three thermocouples were placed between the Cer-wool and the steel bottom plate. Three thermocouples were also placed on the top of the uppermost cover plate. No outer wrap was used to minimize edge losses. The foiled assembly was the same configuration, except -foil was placed between the layer of Cer-wool and mineral wool. Also, foil was placed between each layer of mineral wool thereafter. There were-six (6)' layers of mineral wool, for the foiled assembly. Thermocouples were placed on top of the foil in all cases. 'The thermocouples were positioned as'before, except all thermocouples ,-w., were placed in the projected area of the oven heated space. , V 3. TEST PROCEDURE 1 f A set of zero thermocouple readings were taken, and the oven was then turned on. The temperature controller was set for 1925 F. Every 15 minutes, a complete set of thermocouple readings were taken, and the oven. temperature was recorded every five (5) min- ) utes for the mineral wool assembly without the foil. The assembly with the-foil, had complete thermocouple readings taken every 15 t minutes. Oven readings were not taken on the five minutes, as it was noted the oven was providing reproducible results. The non-foiled assembly is shown in Figures I and II. The foiled assembly is shown in Figures III and IV. 4. TEST RESULTS The tesi results are shown in Figure V. Figure V is the tempera-ture p. file after three (3) hours. The measured Cer-wool curve from 1..-31N plotted in Figure V is a basis for comparison. It is evi -ent from Figure V that mineral wool has a higher thermal diffus.vity than Cer-wool. No attempt to quantify the difference in the; mal diffusivity was made. It is sufficient to say the mineral wool thermal diffusivity was greater than that of Cer-wool. ,_s t 1 y,)

i k t TRANSCO I N C. TEST REPORT No.: TTR-32N L' t l,m. } p ys' I Becausetwo(2)ofthethre.e(3)thermocouplesineachlayerwere outside the projected area of the heated portion of the oven, only the center thermocouple was used to determine the layer temperature in the non-foiled test of mineral wool. The scatter of the points 'about the curve is indicative of the thermocouples not being exactly on center. t The mineral wool with foil curve is a significant result. The addi-tion of foil effectively reduces the thickness of mineral wool nec-i ' essary for the same temperature profile by about two (2) inches. In fact, mineral wool with foil performs better than Cer-wool, al-lowing approximately one inch in thickness reduction. [ rigures VI, VII, and VIII are closeups of the first and second layer { of mineral wool. Figure VI is the bottom of the first layer of' min-eral wool. This face was in direct contact with the Cer-wool. 4 ' Figure VII is the top of the same layer. Notice the decrease in burn diameter. Figure VIII is the bottom of the second layer of mineral wool. Figures VII and VIII are different, because there was.a layer of foil separating the two faces.- ~ Note in Figure VI, the outer dark ring appears to be preliminary 7gQ chnring of the binder. The white ring is total burnout of the birider. The dark inner ring is charring of the mineral wool fibers. There appears to be gradeation in the center circle. No explanation is readily_ apparent for the inner circle gradeation. The diameter of the charred portion of the mineral wool fibers de-creases with increasing distance from the front face of the oven. The diameter on the first layer of mineral wool is greater because i of the large amount of transverse heat transfer in the first layer. The transverse heat transfer is caused by the temperature gradient g in the horizontal plane. Isotherms in the mineral wool pile will approach a hemisphere with the center of the sphere being near the center of the front face of the oven. 5. CONCLUSIONS Mineral wool has a thermal diffusivity greater than that of Cer-wool. Both the Cer-wool and mineral wool were eight (8) pound density mate-rial. Mineral wool required approximately one inch greater thickness than -Cer-wool on a 14-inch pile to produce the same temperature drop be- ' tween hot and cold faces. Or, to produce equivalent temperature m_ ,I'v)

TEST REPORT No.: TTR-32N l i reductions between hot and cold f aces requires approximately 7.5 7. more mineral wool than Cer-wool. By placement of stainless steel foil every two inches _in a stack of mineral' wool, a reduction of approximately 15% in' thickness can be realized for the same hot and cold face _ temperatures. Foil between layers of miner'al wool make a significant difference in effective thermal ~diffusivity. L I i 4 pg e L I e LO A

1 l' Ft /\\ b4 53 C: C) I bJ C. TEST REPORT No.: TTR-33N i s t TEST REPORT TEMPERATURE RESPONSE OF LAYERED CER-WOOL TO A THREE-HOUR ASTM E-119 FIRE TEST WITil AND WITHOUT FOIL BETWEEN LAYERS TEST PERFORMED AT STREATOR, ILLINOIS MAY 24-25, 1983 Test Performed By: W. .M W. D. Brown, P.E. Mgr. Product Development Insulation Products Division Loren Pitts Product and Development Engineer TRANSCO I N C. TEST REPORT No.: TTR-33N 1. INTRODUCTION Transco TTR-30N was performed in an approximately three foot cubed gas-fired floor furnace, at Construction Technology Laboratories in Skokie, Illinois. The temperature / time curve of the oven matches that of ASTM E-119. Transco's recently upgraded oven at Streator, Illinois produces a temperature / time curve nearly equal to that of Construction Technology Laboratories's gas-fired furnace. However, the Transco oven is approximately eight (8) inches by ten (10) inches by twelve (12) inches deep. TTR-31N and TTR-32N were conducted on the Transco, Streator, Illinois oven. The first purpose of this test is to determine if a thick wall of Cer-wool responds identically to an ASTM E-119 temperature / time curve as produced by both ovens. In other words, are the Transco oven tests comparable with Construction Technology Laboratories oven tests. TTR-32N was conducted on a simujated mineral wool wall. TTR-32N results indicated that foils placed every two (2) inches in a thick mineral wool wall resulted in a 15 percent reduction in material thickness required to produce an 1850 F temperature drop. The second purpose of this test is to determine if foil placed be-tween two (2) inch layers of Cer-wool will result in an equivalent reduction in required insulation thickness. 2. TEST APPARATUS The test apparatus consisted of the Transco test oven at Streator, Illinois with associated instrumentation. The oven was rotated onto its back. A 24-gauge stainless steel plate 24 inches square was placed over the eight (8) by ten (10) inch front oven face. Seven (7) layers of two (2) inch thick eight (8) pound density Cer-wool was placed on top of the stain-less steel plate. All layers were approximately 24 inches square. A stainless steel plate was then placed on top cf the assembly. Three (3) thermocouples were placed between each layer; one at the center and two on a common 450 line on each side of the center. Great care was taken to place all three thermocouples in the pro-jected area of the oven. The foiled assembly was the same configuration, except foil was placed between each layer of Cer-wool. The thermocouples were mounted on top of the foil. There was no foil on the top of the Cer-wool pile, just a stainless steel cover sheet. 1 P

^ 4 s -s L' Figure I shows a typical.Cer-wool assembly. In this case, the foiled assembly is shown. 3. TEST PROCEDURE-A set of zero temperature readings were taken, and,the oven was then turned on. The temperature controller was set for 19250F. l Every 15 minutes, a complete set of thermocouple readings were j~ taken. The readings were continued for a full three-hour period. 4 At the end of three hours the oven was turned off, and the insula-tion and steel plates were removed from the oven face. r The oven was allowed to c'ool overnight between the non-foiled and the foiled Cer-wool tests. I LThe same Cer-wool blankets were used for both tests., 4. TEST RESULTS The results are shown in, Figure II,. The first purpose of 'the test was to see if a thick wall of Cer-wool responds identically to an F )- N1 ASTM E-119 temperature / time transient produced by both Construction "\\,,,) . Technology Laboratories's furnace, and Transco's oven. Transco's oven produced a slightly lower temperature curve, on the order of 600F lower, than the Construction Technology Laboratories [ furnace curve. l The two curves are not identical. The thickness is on the order of h(i ~ 0.3 to 0.4 of an inch difference for equivalent temperatures. However, for. experimental purposes the curves are essentially the same. The I: area on the Transco oven' temperature / time curve was approximately five (5) percent less'than the ASTM.E-119 curve..Hence, it is logi-cal the temperature profile of.the Transco oven should be lower than the Construction Technology Laboratories temperature profile. The second purpose of the test.of Cer-wool was to determine if the foil placed between the Cer-wool layers will affect the same change-in required thickness ar the foils between the mineral wool did in TTR-32N. Approximately a two (2) inch reduction in insulation thickness was. realized by the insertion of foil;between the layers 4 4. of mineral wool. 1 -A review of Figure II indicates a thickness reduction on the order i l .of three quarters of an inch will be realized by the insertion of foil every two inches in a 14-inch stack. It appears foil does not make as'significant a difference with Cer-wool as it'does with min-fs 'eral wool, c TRANSCO I N C. . TEST REPORT No.: TTR-33N ) i ~- s On a fourteen (14) inch 1 hick stack, a reduction of 0.8 inches is a six (6) percent thickness reduction. Whereas the mineral wool experienced a reduction of two (2) inches, or fourteen (14) percent. 5. CONCLUSION 1 The Transco oven at Streator, Illinois can be used to predict the results of a thick wall of insulation's response to an ASTM E-119 temperature / time transient. The results compare within experimental limits with the larger gas-fired furnace at Construction Technology Laboratories in Skokie, Illinois. f The use of foil between layers of Cer-wool does reduce the heat transfer through a thick' wall of Cer-wool. For mineral wool, the reduction was on the order of 15 percent, for one foil every two (2) inches. For Cer-wool the reduction was only on the order of six (6) percent. Hence, the effectiveness of the foil seems to be dependent upon the type of insulation the foil is separating. Foil insertion does not make a significant difference in a. thick wall of Cer-wool. f i ~.J h h __/ m i i TRANSCO I N C.

c ' :a 4 W. T R A N S C O I N C. h TEST: REPORT No. TTR-34N 7yq. (g i._X '( ) t a -1. INTRODUCTION U A series.of tests has been performed to determine the amounts of insu-E;1ation necessary to isolate a metal body from the. effects of a three (3) hour fire, as defined by ASTM E-119. i 'It'has been noted in test reports 'TTR-30N through TTR-33N that approx-imate'ly 13 inches of eight (8) Ibe/ft.3 density Cer-wool will isolate .X a fire.from'a steel surface. Adding foil every two (2) inches between the layers of Cer-wool insulation reduces the 13 inches to 12 inches. 'As the purpose of these tests is to develop a fire-resistant wrap that is useable in congested areas, it is important that a minimum thickness insulation be developed. A potential candidate is Microtherm as manu-factured.by Micropore International, Ltd. Microtherm has a high spe-cific heat, low conductivity, and high de'nsity (nominally 12-20 lb./ft.3), Microtherm has physical characteristics that should yield a low thermal diffusivity (thermal conductivity divided by spe#cific heat and density), thus its response to a transient should be slow. In reviewing the literature it was noted that insulation thermal con-ductivities and specific heats for varying temperatures are generally [-,yj' not available. Microtherm does have known properties that indicate' it hasgoodtransientresponsechpraVteristics. Microtherm does reach an equilibrium concentration of moisture with humid air. Normal Microtherm will contain about three (3) percent by weight moisture. Hydrophobic Microtherm will contain about 0.5 per-cent by weight moisture. When heated sudder.ly, conventional Microtherm will pass the steam (water vapor) from the hot face to the cold face. ~If the Microtherm is not in a sealed' container the steam will exit the insulation and diffuse in the air.. In the case of an outer surface being exposed to fire, the moisture will be driven into the interior, or to the body being protected. The steam will stop at the first im-permeable barrier, and condense at 212 F. The heat of condensation will be then transmitted to the body being protected by the insulation. To minimize the steam vapor effect for this test, two precautions are taken. The first is to use Hydrophobic Microtherm so that-the amount of moisture available to handle is minimized. Secondly, a foil barrier is placed near the cool surface to prevent water vapor migration to the steel surface that is being protected from the fire effects. Microtherm also has an upper temperature limitation of 17420F for con-ventional, or 19220F for high-temperature insulation. As the Microtherm Jinsta11ation is for a once-only application, the conventional Microtherm is recommended. Further, to maintain the Microtherm's geometric shape,

,_ }.

an outer wrap of Cer-wool will be provided to protect the Microtherm /. 3 from deformation by the stainless steel lagging. The Cer-wool outer 3 i h - .i n ap,,.. _,...,

r T R A N S C O 'I N C. TEST REPORT No.: :TTR-34N p-h) wrap will reduce the temperature seen by the Microtherm to within its temperature limits also. The Microtherm is normally encapsulated in a fiberglass cloth that loses its strength at 12000F. The Cer-wool outer wrap will hold the Microtherm in place during the fire, even though the. cloth may deteriorate. - Figure 1: shows Microtherm that was placed directly behind the steel plate, with no Cer-wool barrier. The material maintained its integ- .rity until it was physically removed from the oven face, and placed on the floor (from another test). Hence, even though the temperature of the glass. cloth was exceeded,-the cloth maintained its shape until it was disturbed. The purpose of the test is to determine the ability of two (2) inches of Cer-wool and four and one-half (4 ) inches of standard,-Hydrophobic Microtherm'to isolate a steel' body from the effects of a three-hour ASTM E-119-fire. 2. TEST-APPARATUS The test apparatus consisted of the Transco test oven at Streator, Illinois with associated instrumentation. ,A\\_) The oven was rotated onto its back. A 24-gauge stainless steel plate 24 inches square was placed over the eight (8) by ten (10) inch front oven face. One layer of Cer-wool (8 lb./ft.3) two (2) inches thick was placed on top of the plate. Nine (9) layers of Hydrophobic stand-ard temperature Microtherm each 1/2" thick, were placed over the Cer-wool. Between the seventh and eighth layers of Microtherm a layer of -0.002", thick stainless steel was inserted. Three (3) thermocouples were placed on a 45 line'through the center of the oven face, in various horizontal planes. Care was taken to maintain the three (3) thermocouples (two on each side of the one in the. exact center) within the projected area of the open oven. A set of three thermocouples were placed at the following locations: 1. Between the steel plate and the Cer-wool layer; 2. Between the Cer-wool and the first layer of Microtherm (+2"); 3. Between the second and third layers of Microtherm (+3"); 4. Between'the itarth and fifth layers of Microtherm (+4"); 5. Between the sixth and seventh layers of Microtherm (+5"); 6. Between the seventh and eighth layers of Microtherm (+5.5"); 7. Between the top layer of Microtherm (ninth) and the steel plate (+6.5"). 1The Microtherm used for the test was slotted Microtherm. The slots were _ (~ ~s aligned in'the same direction and offset on successive layers. Each piece (,,) of Microtherm was 2' x 3' wide. The offsetting may be seen in Figure III.

A weight was placed on the center of the stack of Microtherm to remove any air spaces between the Microtherm layers and the' steel plates. 3. TEST PROCEDURE of zero After completing the assembling of the test apparatus, a set temperature readings were taken. The oven was then turned on, and the temperature controller was set for 19250F. .Every fifteen minutes a complete set of thermocouple readings were taken. The readings were continued for a full three-hour period. At the end of three hours the oven was turned off, and the insulation and steel plates were removed from the oven face. -There is a heat soaking effect that occurs with the Calcium Silicate insulation in the oven wall. Consequently the oven temperature will. rise-to 19250F, with the controller set for 1850 F. The. controller 0 will hunt about the 1850 F setting (1 8 F). The oven temperature will gradually decrease over a 20-minute period to something on the. -order of 19100F. The controller must then be reset to say 18650F, 0 (~N and the oven temperature will rise to 19250F again (1 8 F). The oven ( ) initially reaches 1925 F approximately eighty (80) minutes into the test.. The oven temperature stabilizes approximately 120 minutes to .130 minutes into the test. Even though readings are taken every fifteen minutes, the oven is normally. checked every ten minutes in the 80-130 minute time to as-sure the 1925 F oven temperature is maintained. 4. TEST RESULTS The test results are shown in Figure IV. The temperature profile shows that at the end of three (3) hours the cold face of the insu-lation was beginning to increase in temperature. From the data sheets, the cold face temperature increased from 830F to 890F at the end of the three-hour test. As there was no calculation performed, there is no theoretical tempera-ture profile to compare the measured temperature profile with. The in-tent of the test was to determine the amount of Microtherm, in a Cer-wool /Microtherm sandwich, necessary to isolate a metal structure from the results of a three (3) hour ASTM E-119 fire. It appears from the graph that two (2) inches of Cer-wool and four and one-half (4 ) -inches of Microtherm will effectively isolate a steel structure from the effects of a three (3) hour fire. </~N \\x_-)

d T R A N S C O. I N C. . TEST. REPORT No.: TTR-34N q. 1 To compare the effectiveness of the Cer-wool /Microtherm sandwich with Cer-wool only, the Cer-wool only curve was placed in Figure IV. -To obtain a-comparative thickness, the thickness required to maintain the cold face temperature at 1000F was chosen for a reference point. 'Six (6) inches of the Cer-wool /Microtherm sandwich is equivalent to approximately twelve (12) inches of Cer-wool. In other words, a 50% l thickness reduction can be realized with the Cer-wool /Microtherm sandwich. _. Figure V is a closeup of the oven / steel plrce interface. A minor amount of heat leakage can be seen, as orange traces. The orange is actual line of sight into the oven interior. Perhaps if the seal at the oven / steel plate interface were better, the rate of oven cycling - would have_been less. The oven cycling was on the order of 3/4 of a minute for a +8 F to -8 F range. Figure VI is the bottom of the first and second layers of Microtherm, after the ASTM E-Il9 temperature curve. Figure VII is the top of the first and second layers of Microtherm. In both pictures, the first layer.is laying on the floor, the second layer is inclined. Note in Figure VI the very distinct projection of the oven face onto l7_ j the bottom of.the fi;st layer. Note on the top of the first layer, the oven projected area image is gone and only the larger discolored area is noticeable (Figure VII). Of interest in both Figure VII, the top of the second layer, and in Figure VIII, the bottom of the third layer, is the small dark spot in the center of the burn area. Comparing this emerging dark spot, with the full dark spot on the bottom of the fourth layer, it appears that'the cloth goes through a burn discoloration, then a whitening, as temperature increases. Reviewing the temperature' profile in Figure IV, and remembering the layers were 1/2" thick, the bottom of the third layer where the burn disappears reached a maximum tempera-ture of about 12000F. The full burning effect is occurring near the bottom of the fourth layer. By Figure IV, this corresponds to a maximum temperature of about-9000F. The top of the fifth layer of Microtherm, in Figure IX, appears to have the discoloration beginning. The discoloration ap-parently.begins (by Figure IV) near 3500F. 0 The cloth that wraps the Microtherm is rated to 1200 F, which is the temperature at which the darkening disappeared. Each slat of Microtherm is about 2.75" wide. From the preceding, the [~}. dark ring occurs at about 900 F. ~It appears the 900 F ring occured at 0 about seven (7) inches from the edge of the 10 inch wide oven face, on ( /; .the bottom face of the first layer of Microtherm.

CONCLUSION From the test results,-Figure IV, a Cer-wool /Microtherm sandwich will effectively isolate the steel structure from the effects of a three (3) hour fire.. A 2 inch thickness of 8 lb. density cer-wool, with 4 inches of Microtherm is sufficient. The outer' cloth wrapping.on Microtherm begins to discolor at about 3500F, fully discolors at about 9000F, and whitens, showing little burn-damage to the eye at about 12000F. From Figure IV, two. inches of Cer-wool and four inches of Microtherm will result in a steel-face temperature of'1000F. + ( g -
