摘　　要：为应对储罐区在火灾事故中存在的高度危险性,本文根据原油储罐火灾火焰规模大、燃烧速度快等特点,使用火灾动力学模拟软件FDS对大型外浮顶原油储罐区全液面火灾进行数值模拟。模型以不同风速(0 m/s、2 m/s、4 m/s、8 m/s)下的外界条件为基础,通过对不同外界条件下的火灾场景分析、火源热释放速率分析、热辐射强度分析,构建了基于FDS模拟技术的储罐区域定性与定量双重维度的动态风险评估体系。为大型原油储罐火灾的应急管理和风险控制提供了有效的理论依据。To cope with the high risk of fire accidents in the storage tank area,this article uses the fire dynamics simulation software FDS to numerically simulate the full liquid level fire in a large external floating roof crude oil storage tank area based on the characteristics of large flame scale and fast combustion speed in crude oil storage tank fires.The model is based on external conditions at different wind speeds(0 m/s,2 m/s,4 m/s,8 m/s),and constructs a dynamic risk assessment system for tank areas based on FDS simulation technology through analysis of fire scenarios,heat release rate of fire sources,and thermal radiation intensity under different external conditions.This provides an effective theoretical basis for emergency management and risk control of large crude oil storage tank fires.
