摘　　要：选取三种低阶煤BL、MD、FJC,应用热重分析仪研究三种煤的燃烧特性,采用作图法确定了三种煤燃烧化学反应的特征参数。结果表明,随着煤化程度的提高,煤的失重速率明显加快,燃烧温度也相应增高。煤样燃烧性能优劣与煤的变质程度有关,煤样的变质程度越高,燃烧反应所经历的时间越长。Three kinds of low-order coal BL, MD and FJC were selected to study the combustion characteristics of three kinds of coal by thermogravimetric analyzer, and the characteristic parameters of three kinds of coal combustion chemical reactions were determined by drawing. The results show that the weight loss rate of coal is accelerated and the combustion temperature increases with the increase of the degree of coalification. The combustion performance of coal sample is related to the degree of coal metamorphism.
