Heat Release Rate Tester

Listing ID #3335717

Asian heat release tester
the test method is based on the observation that, generally, the net heat of combustion is proportional to the amount of oxygen required for combustion. The relationship is that approximately 13,1 × 103 kj of heat are released per kilogram of oxygen consumed. Specimens in the test are burned under ambient air conditions, while being subjected to a predetermined external irradiance within the range of 0 kwm−2 to 75 kw m−2 and measurements are made of oxygen concentrations and exhaust gas flow rates.
the apparatus is made of following parts,
cone-shaped radiant electrical heater
radiation shield
irradiance control
weighing device
specimen holder
retainer frame
exhaust gas system with flow measuring instrumentation
gas sampling apparatus
ignition circuit
ignition timer
oxygen analyser
heat flux meters
calibration burner
data collection and analysis system
side screens
smoke system thermocouple
