有风时大型油罐密封圈火灾下油罐间的安全距离

Safe Distance of Large Storage Tank's Seal Ring Fire Under Wind Condition

针对有风时大型原油储罐火灾安全问题,以密封圈火灾着火油罐作为研究对象,采用编程软件对着火油罐的辐射区域进行模拟计算,进而确定储罐间的安全距离。研究结果表明,风速一定时,辐射热量随着距火焰的距离增加而降低;同一着火油罐,热辐射情况随着风速的加大而加剧;风速为4 m/s时,相邻油罐间的安全距离为31.2 m。

With respect to the security issue of large storage tanks＇ fire, taking crude oil tank＇s seal ring fire as the research object, programming software was used to simulate and calculate the thermal radiation of burning storage tank, which can get the safe distance between the tanks. The study results show that, under the condition of certain weed speed, the thermal radiation decreases with increasing of the distance reaching the burning storage tank. For the same burning tank, with increasing of the wind speed, the thermal radiation increases. When the wind speed is 4 m/s, the safe distance between the tanks is 31.2 m.
