摘　　要：搭建小尺寸油罐沸溢火灾试验模型,采用1∶1、2∶1、3∶1三种油水混合比例研究沸溢火的特性和变化过程,得出沸溢发生时间计算公式。原油沸溢火灾主要分为稳定燃烧阶段、沸溢初期阶段、沸溢阶段。储罐的直径增大,沸溢发生的时间越短。原油发生沸溢时,温度会突然上升至最高值,且油水高度混合比越高,其温度最高值与平均温度值差距越小。A fire test model of small scale oil tank was built to study the characteristics and the process of boil over of oil tank fire and to get the calculation equation of boil over start time. The ratio of oil to water were 1：1 and 2：1 and 3： 1.The boil over of crude oil has three stages of stable combustion, initial boil over and boil over. The bigger the diameter of oil tank, the faster the boil over happens. The temperature will rise to highest value fast when the boil over happens, and the higher ratio of oil to water leads to the smaller different between the highest temperature and average temperature.

关 键 词：油罐火灾 沸溢 油水混合比 最高温度 沸溢时间
