摘　　要：利用德国STA449C型同步热重分析仪分别对5个煤样进行单煤种的燃烧特性热重分析并进行分类,以研究并确定所选煤种。在450 MW和600MW2个负荷点和不同上煤方式下进行热态试验,找出最佳运行工况,提高了机组的经济性和安全性。The paper makes the thermogravimetric analysis and classification of pure coal combustion characteristics of 5-coal sample by synchronized thermogravimetric analyzer, and determines coal type. Based on which the paper conducts the hot-state test at two load points of 450 MW and 600 MW with different ways of coal supply, finds out the optimal operating condition, and improves the economy and safety of the unit.
