摘要
利用热重分析法对三种褐煤及其混煤的热解、着火和燃尽等燃烧特性及其活化能进行了研究。试验结果表明 ,混煤中的单一煤种在混煤燃烧过程中基本保持各自的着火和燃尽特性 ;而其热解特性和活化能与掺混比例有关。提出了能够表征单煤及混煤燃烧性能的综合燃烧特性指数 SN。
The pyrolysis,ignition and burnout characteristics and activation energy of three kinds of brown coal and their blends were studied by thermogravimetric analysis.The experimental results show that the parent coals keep their own individual ignition and carbon burnout characteristics in blend combustion.The pyrolysis characteristics and activation energy of coal blends are decided by the blending rate.Meanwhile,a general combustion parameter S N,which can well indicate the combustion characteristics is proposed in this paper.
