| 摘 要： | 本文运用分形理论对煤的多相燃烧过程进行了探索性研究。根据分形动力学的概念认为；煤的多相燃烧中，反应面积的分形增长有DLC模式和KLC模式，一般情况是这两种模式的迭加。模型还引入了孔洞的合并及煤种的影响因素，初步提出了较有通用意义的燃烧模型。该模型把对碳焦的表面分形与燃烧速率的计算结合起来初步揭示了碳焦结构对燃烧过程的影响。

| Abstract: | It is explorativly investigated that the fractal theory is applied to the research of multiphase coal combustion. According to the conception of fractal dynamics, there exist two fractal growth patterns. The growth of combustion surface is also considered to exist the diffusion limited combustion (DLC) and kinetic limited combustion (KLC) patterns. The amalgamation of pores is also to be considered. Then a general combustion model is proposed, which initially reveals the influence of coal char structure on combustion processes. |
