摘　　要：针对北方采暖地区中小规模城市集中供热普及率相对较低,分散供热锅炉数量大,采暖运行能耗较高、污染物排放大的情况,为推动地区建设背压机供热替代分散锅炉,研究通过建立背压机煤耗特性变工况计算模型,并结合实际调研,找出了现阶段实施背压机供热存在的问题,并提出了建设背压机供热替代分散锅炉的建议。In view of the low popular rate of district heating in 15 Northern provinces and the situation of high energy consumption and high emission of distributive boiler, it＇s a good solution measure to apply the back pressure turbine replacement for distributive boiler. In order to find out problems and promote the back pressure turbine construction, this article puts forward the suggestions for developing the back pressure turbine by means of the analysis of thermal economic for the back pressure turbine under different loading rate combined with the practical investigation of operation benefit of an northern power plant.

关 键 词：采暖能耗 分散锅炉 集中供热 背压机 经济效益
