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
