| 摘 要： | 为了研究超细水雾对煤燃烧的抑制效果，基于小尺寸空间抑制燃烧实验平台，研究了超细水雾对煤燃烧的抑制效果，计算在超细水雾作用下实验空间内部氧气、二氧化碳、一氧化碳体积分数的变化情况以及燃烧空间内不同部位的温度变化情况，并且与煤自由燃烧的情况做对比。研究表明超细水雾对煤燃烧的火灾发展过程有很好的抑制作用。研究结论对超细水雾应用于熄灭矿井煤炭火灾具有一定的指导意义

| Abstract: | In order to research the restraining effect on coal fires by ultra fine water mist, based on the small size space inhibit burning experiment platform , the research on the coal burning inhibition effect by ultra-fire water mist was conducted. The changes of internal oxygen, carbon dioxide, carbon monoxide and the temperature change in different parts of volume fraction for, and were contrasted with the situation of coal natural combustion. It showed that the water mist entrainment can effectively reduce the heat release rate of coal, and inhibit the burning of coal. Conclusion for the water mist entrainment used in coal mine fire extingusishment has certain directive significance. |
