摘要
采用非等温热重分析法研究金属化合物对煤矸石燃烧动力学过程的影响,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,并测算了反映煤矸石燃烧放热特性的差热峰面积指标.结果表明,掺加金属化合物可以降低煤矸石挥发分的初析温度,提高煤矸石的燃烧放热量和燃烬水平.
Gangues are the coal mining wastes with low calorific value and high ash content,and are difficulty to be combusted directly in civil stoves or industrial boilers.This paper reports the experimental results on the thermogravimetric characteristic of Gangue combustion and the influence of various metal compounds upon the combustion characteristic of Gangues.When the content of metal compounds is 1%,the effects of sodium chloride or sodium nitrate and iron oxide are obviously higher than that of calcium oxide additives.
