摘要: 为探究食用油火灾的预防、探测及灭火技术,开展不同直径食用油池火燃烧试验,测量食用油油层温度、火焰及火羽流温度、质量损失速率、以及火焰高度等参数,分析食用油池火的燃烧特性,包括其被加热-自燃-燃烧的引燃过程和油层温度、火焰及火羽流温度、质量损失速率的变化规律;分析食用油池火燃烧速率随油池直径变化的规律,并结合理论公式计算不同油池直径对应的热释放速率。结果表明:食用油池火最大燃烧速率约为2.3 mm/min;油池直径分别为25、40、55、70和85 cm的食用油池火对应的热释放速率分别为20、60、190、375和551 kW。

Abstract: In order to explore the prevention, detection and extinguishing technology of edible oil fires, edible pool fires different in diameter were tested. The parameters of oil layer temperature, flame and plume temperature, mass loss rate and flame height were measured. The combustion characteristics of edible pool fires were analyzed, including the development process of edible oil pool from heating to spontaneous combustion to combustion, the change of the temperature of the oil layer, the temperature of the flame and the fire plume flow, the rate of the mass loss. The effect of diameter of oil pan on burning rate of the edible oil pool fire was analyzed. The heat release rates corresponding to different diameters of oil pan were calculated with theoretical formula. The results show that the maximum burning rate of edible oil pool fire is about 2.3 mm/min, and the heat release rates of edible oil pool fires with 25, 40, 55, 70 and 85 cm diameter are 20, 60, 190, 375 and 55 kW respectively.
