A Numerical Analysis of the Heat-release Rate due to Combustion of Pulverized Coal and Radiative Properties of the Media

Li Cun-shcng  
In this paper the input data required for the mathematical models of radiative heat transfer by means of Monte-Carlo and zone method of analysis are described. The mathematical model for combustion of pulverized coal presented by field et al. is adopted and is represented by a system of first-order non-linear ordinary differential equations, the numeral solution of which is also given here. The " projection theory " is used to evaluate the absorption coefficients of char and ash particles. Details of calculation are given together with a computer program in Fortran by means of which a three dimensional distribution of heat-release rate due to combustion of pulverized coal and radiative properties of the media is obtained. A quantitative analysis of the sensitivity of the various parameters is made. The present program has been used in conjunction with the Monte-Carlo program of radiative heat transfer to predict the heat flux and temperature distribution in the furnace of a 200 MW utility boiler.
