Introduction:
This Flammability Test Equipment is a multi-functional combined
test bench, which can realize the combustion test of large
combustible gas burners and small gas burners for the airborne
equipment, accessories and components in the designated fire zone of aircraft.
The test samples include cables and electrical connectors, hoses and pneumatic components.
Standard:
FAR 25.853 Part II,III,VII
Features
1.The burner consists of elliptical combustion nozzle, igniter,
flame sprayer, spoiler, equalizer, combustion cylinder, muffler and ejector. Burner nozzle is sprayed
with carbon steel.
2.The current equalizer is made of 45 steel or 201 stainless steel.
It is made according to standard drawings to make the air flow more uniform. The defect of
unstable flame temperature caused by non-uniform air flow in the first generation
burner is remedied.
3.The spoiler is made of 45 steel or 201. It is made according to
the standard drawings, so that the air and fuel particles can be
fully mixed, and the flame temperature can be more uniform and stable.
4.Ejector: It plays a key role in air supply control. Provide
sufficient air to the burner flame.
5.The imported muffler eliminates the noise caused by excessive
wind speed.
6.The fuel supply system of burner is composed of special nozzle,
oil guide pipe, oil pressure gauge, solenoid valve, pressure tank, air pressure system, etc.
7.The gas supply system of burner is composed of compressed air
(provided by customers) pressure reducing valve, pressure gauge, pressure regulating valve,
filter and so on. Compressed air source provided by customers: 0.9 MPA, The diameter
of trachea is 25 mm.
8.Equipped with 10KV high pressure ignition system. Ignition wire
is flame-resistant and temperature-resistant.
9.The burner flame is a mixture of air and oil. The temperature
should not be lower than 1200 ±50ºC. Flames are conical in shape; yellow in color.
10.Ignition system, ignition wire has high temperature resistant
material protection.
11.The test frame is the fixed burner frame and the temperature
calibration frame.
12.The burner frame can move forward and backward, left and right.
Adjustable horizontal, 45 degrees and vertical, three positions.
13.A calibration gauge is provided to determine the distance
between the burner and the calibration device and the sample.
