摘　　要：为了减轻LNG接收站集液池池火危害,本文通过减小集液池的表面积尺寸、采用高倍数泡沫系统和采用FOAMGLAS~PFS~系统三个方面展开分析。运用PHAST软件对该集液池池火的热辐射影响范围进行模拟分析,结果发现:同等条件下(如风速、大气稳定度、地表粗糙度等),集液池表面积越小,池火的热辐射影响范围越小;采用高倍数泡沫系统后,集液池的池火热辐射影响范围比无泡沫情况下明显减小。国外已有试验数据证明FOAMGLAS~PFS^(TM)可以达到很好的控火效果,表明在国内推广该法扑救集液池池火具有重要的意义,但仍然需要进一步的研究。In order to reduce the pool fire hazard in the impounding basin of LNG Terminal,reducing the surface area size of the impounding basin,adopting the high expansion foam system and using the FOAMGLAS@ PFSTM system were analyzed in this paper. The heat radiation range of pool fire in the impounding basin was simulated by the PHAST software. Results showed that under the same conditions （ such as wind speed,atmospheric stability, surface roughness,etc. ） the smaller the impounding basin surface area is, the smaller the heat radiation range is, and after adopting the high expansion foam system the heat radiation range is smaller than the absence of foam. The experimental data abroad had proved that the FOAMGLAS PFSTM can achieve a good fire effect of controlling, which has important significance for promoting this method in our country to fight the pool fire in the impounding basin,but further research is still needed.
