地下油料储库火灾分区现象模拟试验与分析

概述了地下油料储库火灾燃烧控制方式、火焰行为及主要影响因素,进行了分区现象模拟试验和分析,结果表明,地下油料储库火灾通常呈现出燃烧区、新鲜空气补充区、烟气流区、过渡区和火焰后面的"惰化区"5区;有上下两层坑道的地下油料储库可呈现出燃烧区、烟气流区、新鲜空气补充区和"惰化区"4区.对引发该现象的机理和影响因素作了简要分析.

Simulating Experiment of Control Mode,Flame Behavior and Zoned Phenomena for Fire in Underground Oil Depot

The zoned phenomenon of the fire in an underground oil depot is introduced and the control mode,the flame behavior and main influence factors of the fire combustion in an underground oil depot are introduced in this paper also. The special zoned phenomena are indicated throw the simulating experiment. The fire zones are generally divided into five zones:flame zone,high temperature thermal plumes zone,fresh air supplement zone,transitional zone and"inert zone". The fire zones in the underground oil depot with the upside and lower ones are divided into four zones:flame zone,high temperature thermal plumes zone,fresh air sup-plement zone and"inert zone". And the mechanism to cause the phenomenon and the factors to influence the phenomena are analyzed briefly in the paper.
