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
