摘要： 为了充分了解沸溢火灾特性，建立了小尺度油罐沸溢火灾特性实验平台，采用混合原油作为实验介质，研究了在水垫层存在的情况下沸溢火灾发生时间及不同参数下沸溢特性.结果表明，沸溢发生时间与参数Ho·D-05具有较好的线性关系，并给出了线性拟合公式.沸溢过程分为三个阶段:稳态燃烧阶段、沸溢前兆阶段以及沸溢阶段.详细探讨了三个阶段水层、油水界面、油层以及火焰的温度变化特性.所得结果为深入理解沸溢火灾机理，探索沸溢火灾防控技术提供指导.

关键词: 油罐, 火灾, 沸溢发生时间, 沸溢特性

Abstract: Experimental device for studying smallscale oil tank boilover characteristics was established in order to fully understand the boilover phenomenon. The mixed crude oil was adopted as medium. The boilover start time and boilover characteristics with different experimental parameters were studied when water layer was present. The results indicated that the boilover start time is linearly proportional to the parameter Ho·D-05， and the fitting equation is given. The boilover process is divided into three stage: the steady combustion stage， the boilover premonitory stage and the boilover stage. Temperatures of water layer， oilwater interface， oil layer and flame of each stage are discussed in detail. The results can be used to better understand the boilover theory and guide the prevention and protection measures from boilover.

Key words: oil tank, fire, boilover start time, boilover characteristics
