摘　　要：建立试验平台,开展水雾和干粉系统对LNG池火的抑制效果研究,通过摄像、温度测试等手段记录试验过程。结果表明,在LNG池火周边布置水雾不能有效抑制LNG池火,但是可以有效阻隔火焰传播,使火焰温度下降约79%;直接向LNG中加水会使火焰突然增大;干粉仅能短暂压制LNG池火火焰而无法将其扑灭;干粉包裹住一部分LNG,降低了池火的燃烧效率,延长了火焰燃烧时间。An experimental platform was built, to conduct the study on the LNG pool fire suppression by water mist and powder fire extinguishing system. The experiment process was recorded by video and temperature test. Results showed that,water mist round the LNG Pool fire can＇t suppress the fire effectively, but can barrier the fire spreading, and lower the flame temperature to 79 %; directly adding water to LNG would increase the flame suddenly; powder can suppress the flame shortly, but can＇t extinguish the fire; powder would envelop some LNG, and lower the combustion efficiency, and lengthen the combustion.
