Abstract
The use of water mist to extinguish fire is a problem of particular interest since the banning of halogenbased agents for environmental reasons This interest is reflected in the large number of researches performed on the main fireextinguishing mechanisms of water mist heat extraction oxygen displacement and attenuation of heat fluxes In contrast there are still little known about the chemical and some other aspects of water mist addition on the pool fire In this paper a phenomenological study was conducted of the effect of water mist addition on the kerosene pool fire through the measurement of the heat release rate CO CO2 and O2 species concentration in combustion The experimental results show that there is a significant enhancement effect at the beginning stage of water mist addition Then the flame size was decreased abruptly By physical suppression effect combined with chemical effect the experiments’ results are explained especially The study of effects of water mist on pool fire will be useful for optimizing designation of water mist firesuppression system improving the fire suppression efficiency and extending their application field
