摘　　要：简述了神东补连塔煤矿40t/h立式煤粉工业锅炉的概况,结合补连塔、中鸡和郭家湾该3种低阶煤煤粉样品的热重分析实验室数据及工业化运行数据的对比分析,指出郭家湾煤着火工艺特性较好,而中鸡煤、补连塔矿的煤质适应性稍差。可通过优化煤粉工业锅炉的工艺参数和及时调整运行参数,加大旋流强度及提高燃烧效率,从而扩展煤粉工业锅炉的煤质适应性。This paper introduced the general circumstances of 40 t/h vertical pulverized coal industry boiler in Shendong Bulianta coal mine, combining with the comparison between thermogravimetric analysis of laboratory data and industrialized operational data （ for 3 types of pulverized coal samples from Bulianta, Zhongji and Guojiawan）, it was indicated that the ignition process character of Guojiawan coal is good, but the coal quality adaptability of Zhongji coal and Bulianta coal is slightly worse. Through the optimization of process parameters of pulverized coal industrial boiler and adjusting the operation parameters, the swirl strength could be enhanced and the combustion efficiency could be improved, so that the coal quality adaptability of pulverized coal industrial boiler could be extended.
