摘    要：为解决传质作用不能忽略时炭粒燃烧反应动力学参数不易精确测定的问题,修改了扩散反应速率计算式和燃烧速率表达式,在此基础上,提出了处理燃烧失重数据的方法。采用此方法,能同时整理出燃烧反应动力学参数和扩散反应速率系数,本方法主要适用于气体温度低于1300K的燃烧情况。

Abstract: he modifications of both the formula for the combustion rate of char and the formula for the mass transfer coefficient are presented in this paper, Then the method of managing the experimental data on weight losses of char during combustion is described using the method, which is suitable to the combustion of char with gas temperature lower than 1300K,The kinetic parameters of combustion and the mass transfer coefficient can be obtained at the same time.
