摘要： 采用实验室压缩气体泡沫系统，通过油盘火对比试验，分别考察基于不同气源的压缩气体泡沫对于120#溶剂油火灾的灭火性能，分析探讨适用于常规B类火灾扑救的气源类型和供气方案。结果表明，在泡沫溶液供给强度为2.5 L/（min·m2）的条件下，压缩氮气泡沫和压缩空气泡沫均可扑灭120#溶剂油火灾，都具有良好的抗烧和抗复燃性能；压缩氮气泡沫比压缩空气泡沫的控灭火性能略有提升，但二者差别不大；对于常规B类非极性燃料火灾，实际工程中有氮气源的场所建议直接采用已有供氮气设备作为供气源。

Abstract: The fire extinguishing performance of compressed gas foam based on different types of gas on 120# solvent oil fires was compared by pool fire tests using a laboratory compressed gas foam system. The types of gas source and gas supply equipment suitable for ordinary class B fire were investigated. The results indicate that both compressed nitrogen foam and compressed air foam can extinguish 120# solvent oil standard fuel fires and have good anti-burning and anti-reburning performances under the condition of the foam solution foam application rate was 2.5 L/(min·m2). Compared with compressed air foam, compressed nitrogen foam has a slightly improved fire-fighting performance. However, the difference between them was not significant.For ordinary class B fire, it is recommended to directly use the existing nitrogen supply equipment as the gas supply source for places with nitrogen source in the actual project.
