摘　　要：为解决使用原位燃烧法(ISB法)处理漏油时,不同水质边界对燃烧效率、除油效果产生的问题,分别对6~20 cm圆形直径油池火的燃烧特性进行实验研究。通过对3种水质边界下柴油池火的燃烧速率、火焰温度、火焰高度的对比分析,结果表明:不同水质边界下柴油池火燃烧可分为3个阶段:引燃阶段、稳定燃烧阶段和熄灭阶段。针对稳定燃烧阶段,由于水质边界的成分与相态不同,燃烧速率各有差异,其中海水边界下池火的燃烧速率最快,而冰边界远小于前两者,针对该现象建立传热模型进行分析,建立了适用于3种水质边界条件下预测火焰高度的数学模型。In order to solve the problem of the combustion efficiency and degreasing effect of different water quality boundaries on the oil leakage treatment by in-situ combustion method(ISB method),the combustion characteristics of 6~20 cm circular diameter oil pool fire were experimentally studied.Through the comparative analysis of the combustion rate,flame temperature and flame height of diesel pool fire under three water quality boundaries,the results showed that the com-bustion of diesel pool fire under different water quality boundaries could be divided into three stages:ignition stage,stable combustion stage and extinguishing stage.In view of the stable combustion stage,due to the different components and pha-ses of the water quality boundary,the combustion rates were different.The combustion rate of the pool fire under the sea-water boundary was the fastest,while the ice boundary was much smaller than that of the first two.We built heat transfer model and analyzed it based on the phenomena,and it was established that a mathematical model for predicting flame height under three water quality boundary conditions.
