摘要: 采用三维 CFD 火灾模拟软件 KFX 对某原油罐区不同尺度池火场景进行模拟。通过计算不同泄漏孔径下的泄漏速率,确定不同尺度的池火面积。在进行池火模拟时考虑不同的风向、风速以及罐区几何结构特点,得到不同热辐射通量的影响范围以及被火焰包裹的设施所受到的热辐射通量。结合模拟结果,分析了按照国内相关设计标准设计的罐区在不同池火场景中的安全状态和事故升级可能性。为罐区安全设计拓宽了思路,同时解决了应急准备分析中面临的实际问题。

Abstract: Different pool fire scenarios of a crude oil tank farm are simulated by CFD fire modelling tool KFX. Sizes of pool fire areas are calculated based on different leak hole sizes. Wind directions, wind speeds and the tank farm geometry characteristics are taken into consideration in the study. The effect distances of different heat radiation fluxes and the heat radiation flux received by the elements engulfed by flame are taken from the fire simulation results. The safety status and the escalation potential of various fire scenarios are assessed for the tank farm designed with applicable Chinese national standards, which provides more references for the tank farm safety design. Some practical issues of the emergency preparedness analysis are also resolved through the assessment.

Key words: crude oil tank farm, pool fire, CFD, KFX, effect distance, emergency response
