FAQ:
Q:How to use SBI?
A:The test is carried out in a combustion chamber with a height of 2.4m and an area of 3m X 3m. There is a gas collection hood and a smoke exhaust pipe connected to the sampling pipe on the top of the room, and there is a space for air to flow in and out naturally under the trolley.
During the test, the heat released by the combustion of the sample and the combustion products must be discharged from the exhaust pipe. A comprehensive sampling area is provided in the smoke exhaust duct for placing sensors and sampling pipes. Measure gas temperature, combustion release compound concentration, oxygen concentration, light attenuation of flue gas, total flow of air and combustion products in the sampling pipe.
