摘要
回燃是在通风受限的建筑火灾进入缺氧燃烧甚至闷烧后,由于新鲜空气的突然大量补充引起热烟气急剧燃烧的现象。目前腔体回燃的研究已取得很多有价值的成果。在总结前人研究成果的基础上,结合地铁火灾的特点,指出地铁火灾中也存在回燃现象,并简略地提出了针对地铁火灾中回燃现象应进行的研究内容。
Backdraft phenomenon is the fire phenomenon in vitiated buildings where the hot gas rapidly combusts due to abruptly supply of abundant fresh air after combustion with lack of oxygen or even smoldering. At present, the research of the compartment backdraR has obtained a lot of valuable conclusions. Based on the existing study to backdraft and the characteristics of the subway fire.This paper indicates that the backdraft is able to break out in the subway fire and the research contents needed to be done aimed at the subway backdraft.
