Title |
Description |
| 1 |
Metal Shield (Fire Chamber) |
16 gauge sheet metal housing
36 in. x 48 in. x 42 in. (0.9m x 1.2m x 1.2m) with one
end open. This protects the test unit from the environmental
elements. |
| 2 |
Test Viewing
Cover |
High temperature
glass approximately 42 in. x 54 in. x 0.25 in. (1.1m x
1.4m x 0.6cm) used as fourth side of metal shield. Should
be capable of completely sealing off this side and withstanding
approximately 1600°F (871°C). |
| 3 |
Fuel Pan |
Sheet metal pan approximately
8.5 in. x 14 in. x 1.5 in. (0.2m x 0.4m x 3.8 cm) for
holding fuel in metal shield. Sides of pan should be outside
perimeter of test component. |
| 4 |
Thermocouple |
Thermocouple
with remotely readable indicator for temperatures to 2000°F
(1093°C) (Two required). The thermocouple shall be
an open tip chrome-alumel thermocouple probe with bare
thermocouple tip with stainless steel tubing and Formica
insulation. The thermocouple wire size shall be smaller
than 22 gauge. |
| 5 |
Fuel Tank |
Holding tank for fuel to be
passed through test units. |
| 6 |
Shutoff
Valve |
Fuel
tank shutoff.
Note: This may be an integral part of the fuel tank,
it is not mandatory that it be installed, however, it
is recommended as a safety precaution. |
| 7 |
3-way Fuel Valve |
Three-way, two-position valve
for supplying fuel to the test component and then venting
test component fuel fill line to atmosphere |
| 8 |
Discharge
Valve |
Fuel discharge
shutoff valve to verify the test component is filled with
fuel and then stop fuel flow through the discharge line. |
| 9 |
Receiving Pan |
Open top pan to collect the
fuel flowed through the test component. |
