| 摘 要： | 在一些柴油油池火实验数据基础上,分析了油池火的初期增长过程以及影响油池火燃烧的因素．油池火由引燃至开始稳定燃烧的增长过程分为两个阶段:第一阶段约占增长过程的1／3,可通过时间平方增长来近似,其增长系数介于0．12-0．28之间;第二阶段约占增长过程的2／3,也可用时间的二次曲线来模拟其增长过程．油池火的稳定燃烧速率和热释放速率随着油面面积的增大、通风条件的改善而增大,其燃烧效率介于0．68-0．85之间．

| Abstract: | The increase process of pool fire burning diesel oil and some factors affecting the burning of the fuel are discussed based on some experiments. The increase process of the pool fire after ignition can be divided into two stages: the first stage takes up about 1/3 of the whole increase process and can be modeled as t-squared increase with an increase factor lying from 0. 12 to 0. 28; the second stage takes up about 2/3 of the whole increase process and can be modeled as a quadratic curve of time. The burning rate and heat release rate per unit area increase along with the increase of burning area and improvement of ventilation conditions. In the tests, the combustion efficiency of diesel oil lies between 0. 68 and 0. 85. |
