Abstract�� In order to research on fire extinguishing characteristics and rules of water mist under different heat release rate conditions, seven heptane-pan fire of different sizes were applied to single-nozzle and four-nozzle fire extinguishing experiments in the compartment of 4.6��m×3.3��m×4��m. Thermocouple tree and gas analyzer were used to measure flame temperature and oxygen concentration around the flame during the experiment. The characteristics rules of water mist fire extinguishing under different heat release rate conditions and change rules of flame temperature field during fire extinguishing were obtained respectively. The design and test standard method of water mist fire extinguishing system and the development criteria of water mist fire extinguishing products were provided from the experiment.
Keywords�� water mist   fire extinguishing   pool fire   heat release rate
