水浴保护对甲醇池火燃烧速率的影响

The effects of water bath on the burning rate of methanol pool fire

试验研究了水浴对不同尺寸甲醇池火燃烧速率的影响。燃烧盘与水浴盆均为正方形。结果:在水浴条件下,在稳定燃烧阶段的池火燃烧速率曲线比较平滑;在快速上升阶段,池火燃烧速率与油池尺寸及有无水浴关系不大;在下降阶段,有水浴的条件下,燃烧时间有所延长;在稳定阶段,有水浴时燃烧速率小于无水浴时,一般不超过10%。

The effects of water bath on the burning rate of methanol pool fire with different pool sizes have been experimentally studied.The burning pool and water bathtub are square.Results：At steady burning stage,the burning rate curve of the pool fire is relative smooth in the presence of water bath.At rapidly growing stage,the burning rate of the pool fire has less to do with the pool size and the condition of with or without water bath.At slowly decaying stage,the burning time in the presence of water bath is longer.At steady stage,the burning rate of methanol in presence of water bath is less than that of the condition without water bath,and is no more than 10%.
