摘要
分析了火球热辐射的特点,针对LPG沸腾液体扩展蒸气爆炸火球造成的热辐射危害存在不确定性,建立了爆炸火球热辐射风险评估模型,提出了一种基于Monte-Carlo模拟的不确定性处理方法,引入实例计算了LPG沸腾液体扩展蒸气爆炸火球伤害范围、事故风险概率曲线方程和累计概率曲线方程,对于定量评估火球热辐射风险具有重要意义。
Characters of fireball heat radiation has been analyzed. This paper aimed at which the hurt result from boiling liquid expanding vapor explosion （BLEVE） fireball are uncertain, the risk assessment model of fireball heat radiation has been developed and MC simulation of uncertainty analysis method has been put forward. Through the accident cases, the method has been expatiated. Hurting scope of fireball, the equations of accident risk probability curve and accumulative probability curve have been confirmed which analysis is significance to assess risk of fireball heat radiation quantitatively.
