Experiment of heat release rate of pool fire effect on water mist fire suppression

School of Astronautics, Beijing University of Aeronautics and Astronautics, Beijing 100083, China

摘要

摘要: 为了研究细水雾针对不同热释放率条件下的灭火特性及规律,采用7种不同尺寸油盘火模型和正庚烷燃料,在4.6m×3.2m×4m的空间内,进行了单喷头和四喷头灭火试验,试验过程中采用热电偶树和气体分析仪对火焰温度及火场氧浓度进行了测量,得到了不同热释放率条件下的细水雾灭火特性规律和灭火过程中火场温度场的变化规律,为细水雾灭火系统设计、检验标准制定及细水雾灭火产品开发提供了相应的试验依据.

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.
