贮油罐的爆炸模拟试验

Laboratory Simulation of the Explosion of Large Oil Storage Vessels

对大型贮油罐爆炸的危险性进行室内模拟试验。用乙炔/空气和液化石油气/空气作为模拟气体。将满罐充气和半罐充气点火爆炸,与不同药量的TNT炸药在罐中爆炸作对比,从而确定模拟气体爆炸气体TNT当量值。同时测定模拟防火墙位置上平均迎面、侧面和背面超压值。结果表明1×10~4m^3贮油罐爆炸时其威力量级为588kgTNT当量;满罐充气爆炸时,模拟防火墙上载荷为9.5kPa。本文对实际贮油罐爆炸威力进行了估算,其量级与实际结果相一致。

A series of laboratory simulation for the accidental explosion of large oil storage vessels have been undertaten . Acetylene / Air and LNG / Air mixture gases were used , and compared with TNT explosion , and the TNT equivalents for the mixture gases were determined . Also the explosion loading on a fire - resistance wall were obtained . The experimental results show that the TNT equivalent of a 1 × 104m3 oil storage vessel is 558kg . The over - pressure on the fire - resistence wall is about 9-5 kPa . The explosion intensity of the oil storage vessels is evaluated .The order of explosion intensity as evaluated is consistent with those obtained form the experiments .
