摘要/Abstract

摘要： 通过大尺度池火灭火试验，验证了泡沫叠加灭火法在大型甲醇池火灭火过程中的实际效果，主要考虑了风向、泡沫混合液供给强度对泡沫铺展效果和灭火速率的影响，同时分析了泡沫叠加灭火机制，试验过程由测温、摄像设备全程记录。结果表明，AFFF/AR叠加灭火适用于甲醇池火扑救；AFFF/AR混合液供给强度越大、顺风风力越大，泡沫铺展越快、灭火速率越高；在灭火过程中，适当降低AFFF/AR混合液供给强度能提升泡沫原液灭火效能并减少环境污染。

Abstract: Abstract: This paper validates the practical effect of foam stacking fire extinguishing method in large?scale methanol pool fires through large?scale pool fire extinguishing experiments. The main considerations are the influence of wind direction and foam mixture supply intensity on foam spreading effect and fire extinguishing rate. Meanwhile, the foam stacking fire extinguishing mechanism was analyzed, with the whole process of the experiment recorded by temperature measurement and camera equipment. The research results show that AFFF/AR stacked fire extinguishing is suitable for extinguishing methanol pool fires; the larger the supply intensity of AFFF/AR mixture and the stronger the downwind force, the faster the foam spreading and the higher the fire extinguishing rate. During the fire extinguishing process, appropriately reducing the supply intensity of AFFF/AR mixture can enhance the fire extinguishing efficiency per unit of foam concentrate and reduce environmental pollution.
