摘　　要：通过模拟油罐灭火试验,对液下喷射压缩空气泡沫的灭火性能进行了评估。试验结果表明,液下喷射压缩空气泡沫抑制油罐火灾具有可行性,试验中采用氟蛋白泡沫灭火剂和水成膜泡沫灭火剂均可以取得较好的控、灭火效果,不同品牌泡沫灭火剂之间的灭火效果并无显著差异。发泡倍数对灭火效果的影响起主导作用,液下喷射压缩空气泡沫的适宜发泡倍数范围为4～8倍,并应按泡沫灭火剂原设计混合比使用。The fire performance of submerged jetting compressed air foam was evaluated by stimulated oil tank extinguishing ex- periment. The results show that submerged jetting compressed air foam is feasibly to extinguish oil tank fire. Using fluoropro- tein foam and AFFF can get a better fire control and extinguis- hing effect. There is no significant difference in fire control effect between different brands. Expansion is the leading factor affecting the extinguishing effect, and the proper expansion for submerged jetting compressed air foam is 4--8 times, with the original mixture ratio.
