摘要
基于建筑防火隔离带的设计理念,研究了黄磷储罐临界安全距离的计算方法,将黄磷储罐火灾简化为罐内池火模型,通过理论计算和数值模拟黄磷储罐火灾周边热辐射分布,根据目标可燃物接受到的临界辐射通量是否大于或等于10 kW/m2来确定临界安全距离。研究表明:临界安全距离可通过火焰对目标可燃物接受到的临界辐射通量求得,且理论计算和数值模拟计算获得的临界安全距离基本一致。对于黄磷储罐火灾的防治具有一定的参考价值。
Based on idea of building fire barrier,the critical safe distance of Yellow Phosphorus tanks was researched.Yellow Phosphorus tanks fire simplified for the pool fire model.The theoretical calculation and numerical simulation were applied on peripheral thermal radiation distribution of Yellow Phosphorus tanks fire,and the critical thermal radiation flux received by target fuel was compared with thermal radiation flux of 10 kW/m2 in order to determine critical safe distance.The result showed that critical safe distance depended on critical radiant flux of target fuel originating from the flame and critical safe distance by theoretical calculation was basically same to the result by numerical simulation.Valuably,it can be beneficial to control Yellow Phosphorus tanks fire.
