摘要
通过对池火灾热辐射通量三种模型:点源模型、Shokri-Beyler模型和Mudan模型的研究,分析了池火表面总热辐射能量、表面热辐射通量以及目标接受的热辐射通量,总结了各种模型的特点和适用条件。以苯储存罐区为例,利用池火危害分析得出的结论,发现选用Shokri-Beyler模型,计算苯罐区发生泄漏火灾时的池火热辐射通量最为精确,并由此得出消防系统控制阀和消防炮与被保护对象之间的安全距离,以及消防救援的安全距离。
Through studying on the three models of thermal radiation flux of pool fire: point source model,Shokri-Beyler model and Mudan model,the article analyzes the total thermal radiation flux of total surface thermal radiation energy of pool fire,surface thermal radiation flux and target received thermal radiation flux. It summarizes the characteristics of various models and their applicable conditions. Taking the benzene storage tank area as an example and using the conclusions obtained from hazard analysis of pool fire,it is found that the most accurate results for the thermal radiation flux of pool fire when fire occurs due to leakage in the benzene storage tank area can be gained by selecting Shokri-Beyler model for calculation. Thus the safety distance between the control valve of firefighting system and fire monitor and protected storage tank is acquired as well as the safety distance for fire rescue.
