摘要
以傅维镳教授提出的煤焦非均相反应动力学新思想为基础,将Fb数和Fz数引入计算,建立了炉膛的一维模型,推导出一种计算煤焦颗粒燃烧速率的简易表达式,采用划分网格的方式可将这种表达式应用在燃烧速率的求解过程中。
This paper is based on the new idea proposed by Fu W. B. on file kinetics in non homogeneous reaction of char in the boiler. Two dimensionless variables, including Fb and Fz number, are used firstly in the reaction equation in the furnace. An one - dimension model of the furnace is built and a simple expression to calculate the burning rate of char particles is obtained. Dividing the furnace into finite grids, the new expression can be applied to determine the burning rate of char particles.
