摘　　要：为考察水成膜泡沫抑制大型油池火灾的有效性,以火羽流形态、火场能见度、火场温度和灭火时间为有效性对比指标,在机库火灾试验场中开展水成膜泡沫的全尺度灭火试验研究。结果表明:水成膜泡沫灭火剂能够扑灭开放油池火,但无法扑灭遮挡油池火。开放油池灭火过程中,随着油池规模的增加,火羽流形态变化情况相似,火场能见度逐步降低,火源周边及火焰核心区域温度均能迅速得以有效抑制,灭火时间相近。In order to investigate the effectiveness of AFFF in suppressing large-scale pool fire,a full-scale fire extinguishing test was conducted in an existing hangar fire testing field,taking fire flume morphology,visibility and temperatures in the fire zone and fire extinguishing time as comparable firefighting effectiveness indicators of AFFF.Results showed that AFFF could successfully extinguish open oil pool fire,but failed to put out obstructed oil pool fire.In the open oil pool firefighting process,with the oil pool scale increasing,fire flume morphology varied in a similar manner:visibility in the fire zone reduced gradually,and temperatures both around the fire and in core area of flame decreased rapidly,while the fire extinguishing time was nearly the same.
