摘要/Abstract

摘要： 为研究储罐区发生池火灾时多米诺效应对周围人员及临近储罐的影响,利用180号燃料油开展3组大尺度池火灾试验。首先将所测温度转化为相应的热辐射值与理论值进行对比;然后根据实测热辐射均值,结合人员伤害曲线,分析热辐射对周围人员的伤害情况;最后根据试验结果和理论分析得出临近储罐的损害概率。结果表明:风的速率和风向影响池火燃烧,从而影响其热辐射的传播,即风速越大,下风向接收的热辐射强度越大;风速越不稳定,热辐射波动越大;当热辐射强度足够高时,人员在很短的暴露时间内,即使在远离火灾的地方仍可能受到严重的伤害;压力储罐比常压储罐更容易发生二次事故。因此,池火灾发生时,为预防多米诺效应的发生,要优先给下风向压力储罐降温。

Abstract: To study the damage of domino effect in pool fire in tank farm to the surrounding personnel and the adjacent tanks, three large scale pool fire tests were done by using 180# fuel oil. The measured temperatures were converted to the thermal radiation values, and a comparison was made between them and the theoretical calculation values. According to the measured mean thermal radiation and the personnel injury curve, the injury of thermal radiation to the surrounding personnel was analyzed. Finally, on the basis of both the experimental results and the theoretical analysis, the damage probabilities of adjacent tanks were obtained. The results show that both the speed and the direction of the wind affect combustion of fire, affecting the propagation of heat radiation accordingly i.e. the greater the wind speed is, the greater the received thermal radiation intensity at the downwind will be, that the more unstable the wind velocity is, the greater the thermal radiation fluctuation will be, that when the thermal radiation intensity is large enough, the personnel may suffer serious injuries in a short exposure period even at a long distance from fire, that pressure tanks are more prone to secondary accidents than atmospheric tanks, and that in order to prevent the occurrence of domino accidents, priority should be given to cooling down the pressure tanks at the downwind.
