Specification
The test device includes test chamber, control room, dolly, exhaust
duct, data acquisition and analysis device, and air supply control
device.
1. test chamber: L3000*W3000*H2400(MM), connected with extraction
and exhaust ducts at the top of the test chamber, with space for
natural gas to enter and exit the blowing trolley.
During the test, the combustion heat release and combustion
products of the sample can be discharged from the exhaust duct.
