摘要
为解决使用就地燃烧法(ISB)处理海面溢油时,燃烧效率低,除油效果不理想的问题,使用轻质原油在宽阔水面油池火试验装置中开展小尺度模拟试验。首先,设计宽阔水面油池火试验装置模拟就地燃烧处理过程;然后,测量火焰高度、系统温度和燃烧残渣质量;最后,研究不同油池直径和初始油层厚度下平均火焰高度的变化。结果表明:宽阔水面油池火的燃烧可以分为4个阶段;热波传递是沸溢产生的主要原因;燃烧效率与油层厚度呈正相关。
In order to improve combustion efficiency and oil removal effect when using ISB combustion method to deal with oil spill on the sea surface,a series of small scale simulation experiments using light crude oil were carried out. Firstly,test device for pool fire on water surface was designed to simulate the in-site combustion process. Then the combustion process was studied by measuring the flame height,temperature and burning efficiency. Finally,the influence of pool diameter and initial fuel-layer thickness on flame height were discussed. The results show that the combustion of oil pool fire on water surface can be divided into four stages,that the heat wave propagation is the main cause of boiling over,and that combustion efficiency is positively correlated with oil layer thickness.
