【摘要】：统计分析国内外71起储罐火灾案例,表明密封圈火灾是浮顶罐火灾最主要的火灾形式。从点火源分析,雷电是密封圈火灾的主要点火源。以某输油站为例,通过FLACS软件模拟两种场景下的密封圈油气泄漏状态,模拟结果显示防火堤是油气泄漏中的危险部位,油气会在防火堤处积聚,且风速越大,油气积聚的速度越快。建议在防火堤处安装可燃气体监测装置。
[Abstract]:According to the statistical analysis of 71 cases of tank fire at home and abroad, the sealing ring fire is the main fire form of floating roof tank fire. From the analysis of ignition source, lightning is the main ignition source of sealing ring fire. Taking a certain oil transportation station as an example, the oil and gas leakage state of the sealing ring under two scenarios is simulated by FLACS software. The simulation results show that the fire breakwater is a dangerous part of the oil and gas leakage, and the oil and gas will accumulate at the fire protection embankment, and the greater the wind speed, the greater the wind speed. The faster oil and gas accumulate. It is recommended that flammable gas monitoring devices be installed at the embankment.
