半焦粒子团燃烧模型与计算分析

Group Combustion Model and Calculating Analysis of Semicoal Particles

本文针对半焦粒子团燃烧现象，建立了球对称粒子团燃烧的准稳态模型，对粒子团的燃烧速率和粒子温度进行半分析、半数值求解，并具体针对由大径粒子（ａ＝１ｍｍ～６ｍｍ）和小径粒子（ａ＝３８μｍ～５０μｍ）所组成的粒子团的燃烧参数进行了计算，对计算结果进行了分析比较。

This paper introduces the combustion state of cloud of semicoal particles, develops a QS model for group combustion of a spherical cloud of semicoal particles, obtains results on the burning rate and particle temperature of a cloud of semicoal particles, and uses the results from group combustion theory to give the comparision between cloud of big radius particles ( a =1 mm～6 mm) and cloud of small radius particles ( a =38 μm～50 μm).
