烃类流体火灾伤害破坏作用定量分析

对烃类流体火灾的伤害破坏作用进行正确的定量分析是开展重大消防目标火灾风险评估工作的基础。针对烃类流体火灾伤害破坏作用定量分析中存在的问题,系统论述烃类流体火灾伤害破坏作用的定量分析方法,分析并讨论火球、池火、喷射火和蒸气云火灾等不同火灾形式的热辐射通量计算模型及其前提条件,对不同热辐射伤害破坏作用准则及伤害概率模型的适用条件和模型基础进行了论述。

Quantitative Analysis of Thermal Radiation Damaging Effects Caused by Liquid or Gaseous Hydrocarbon Fires

To correctly quantify the thermal radiation damaging effect of liquid or gaseous hydrocarbon fires is the prerequisite to assess the risk of major fire hazards.Aiming at the problems existing in the quantitative analysis of thermal radiation damaging effects caused by hydrocarbon fires,the quantitative analysis methods are systemically expounded;the calculating models and hypotheses of thermal radiation flux for fireball,pool fire,jet fire and vapor clouds fire are discussed;different criteria for thermal radiation damaging effect and precondition for damage probability models as well as its model basis are detailed.
