摘要:
该文对细水雾与固体木垛火相互作用问题进行小尺度模拟实验研究。利用热电偶、数码摄像机等测量了细水雾作用前后燃烧场的变化特征。结果表明:细水雾扑灭木垛燃烧的明火效果较好,但不能有效抑制阴燃现象,且喷雾气压、预燃时间和木垛结构形状对灭火过程有显著影响。在一定范围内,喷雾气压与灭火时间成反比关系;预燃时间与灭火时间成正比关系。
Abstract:
The interaction of water mist with wood crib flame is studied by smal-l scale experiments. Thermocouples and digital video are used to measure the characteristic parameters of the burning area. The results show that the water mist can effectively restrain the surface fire from the wood crib fire, but not as effective for the dark burn and that the suppression process are influenced by the gas pressure of inject ion, precombustion time and the shape of the crib. Within the certain bounds, the gas pressures of injection depend inversely as the time of fire suppression, the precombust ion time depends directly as the time of fire suppression.
