摘　　要：介绍油罐燃烧辐射模型。采用数值模拟方法,通过设置不同油罐直径的火灾场景,利用FDS模拟油罐火灾的发展过程,分析油罐着火时油罐周围不同时刻、不同位置处的温度分布。将油罐的温度分布规律与火焰电荷分布研究相结合,可以为合理布置油罐、科学设置防火间距提供理论分析,同时还可以为处置油罐火灾,迅速准确安排灭火人员和器材于最佳的位置进行灭火,充分发挥灭火剂的效能、及时扑救火灾并且保证灭火人员和车辆器材的安全提供理论基础。The model of oil tank fire radiation was introduced, the numerical simulation was.carried out by setting the fire sce- nario with different tank diameters, and by FDS, to simulate the development of the oil tank fire. The distribution of temper- ature field around oil tank at different time and location was an alyzed. By combining the temperature distruibution rules and flame charge distribution study, theoretical analysis can be pro- vided for reasonable locating tank, scientific setting fire dis- tance, tank fire disposal, fire-fighter and equipment arrange- ment optimization, improving fire extinguisher effectiveness. fire-fighting on time and ensuring the stuff and facihy safety.
