摘要:
为了分析不同通风条件对柴油池火燃烧特性及引燃特性的影响，进行205 mm带水垫层柴油池火的引燃实验，通过对池火燃料的质量损失速率、火焰高度、温度及热辐射等的监测，分析通风环境中柴油池火的热传递规律。结果表明：当风速为0.5 m/s时，火灾进入旺盛阶段的时间提前，火焰平均温度最高；当风速为1 m/s时，风速的增加导致油池火的质量损失速率增加，位于主火源下风向的待引燃火源获得的热辐射通量增大，火灾旺盛阶段火焰的平均温度降低，火焰高度降低，下风向相邻油盘引燃的时间提前；1 m/s情况下，205 mm带水垫层柴油池火的安全间距需增加到1D以上；通风环境对池火发展及蔓延的影响是显著的，应适当加大下风向可燃物的安全间距，合理选择通风排烟风速，优化火灾应急救援策略。
Abstract:
To analyze the influence of different ventilation conditions on the combustion and ignition characteristics of diesel pool fire, the ignition experiments on diesel pool fire of 205 mm diameter with water cushion layer were conducted. The heat transfer rules of diesel pool fire in the ventilation environment were analyzed through measuring the mass loss rate, flame height, temperature and thermal radiation of pool fire fuels. The results showed that when the wind speed rose to 0.5 m/s, the time to the developed stage of fire was shorten, and the average temperature of flame at the developed stage of fire increased to the maximum value. When the wind speed was 1 m/s, with the increasing of wind speed, the mass loss rate increased, the thermal radiation flux obtained by the fire source awaiting ignition on the downwind direction of main fire source increased, the average temperature of flame at the developed stage of fire decreased, and the flame height decreased, so the downwind oil pool was ignited earlier. Thus the safety distance for the diesel pool fire of 205 mm diameter with water cushion layer should be increased to above 1D. The ventilation environment has significant impact on the development and spread of pool fire, so the safety distance for the downwind combustibles should be enlarged, the wind speed of ventilation and smoke extraction should be reasonably selected, and the emergency rescue strategies should be optimized.
