摘　　要：采用非等温热重分析法研究煤矸石燃烧动力学过程，通过热重（ＴＧ）、差热（ＤＴＡ）、微商热重（ＤＴＧ）实验，提出煤矸石挥发分析出过程的特性参数和反应动力学方程，测算了反映煤矸石燃烧放热特性的差热峰面积指标，并分析探讨了氯化钠等碱金属化合物对煤矸石燃烧动力学过程的影响规律。The gangues are coal mining wastes with low calorific value, high ash, and full of difficulties to be combusted in civil stoves or industrial boilers directly. This paper reports the experimental results on the thermogravimetric characteristic of gangue combustion and the influence of various alkali metal compounds upon the combustion characteristic of gangues. When the content of alkali metal compounds is 1%,the effect of sodium chloride or sodium nitrate and iron oxide are higher than that of calcium oxide additives obviously.
