 Heat Release Rate Test Apparatus

Heat release rate test device is a kind of experimental equipment used to measure the heat released by materials under fire conditions.


Equipment structure:

  1. Combustion Chamber: An enclosed space where the sample to be tested is placed, usually with controlled temperature and atmosphere.

  2. Gas Analysis System: Used to measure the gas components produced during the combustion process, such as carbon dioxide, carbon monoxide, etc., in order to evaluate the composition of the combustion products.

  3. Heat Release Rate Measurement System: Used to measure the amount of heat released by the sample during the combustion process in real time, usually using sensors such as heat flow meters or thermocouples.


Test Method:

  • Constant Pressure Method: The sample to be tested is combusted at a set pressure and the amount of heat released during the combustion process is measured to determine the heat release rate.

  • Constant Volume Method: The sample is burned at a set volume and the heat released during combustion is measured to determine the rate of heat release.


Test Parameter:

  • Heat Release Rate (HRR): The amount of heat released per unit of time during combustion of a material, usually expressed as thermal power per unit area (kW/m²).

  • Peak Heat Release Rate (PHRR): The maximum heat release rate achieved during combustion, usually an important parameter in the combustion process.
