摘　　要：随着经济发展,对环境保护的要求越来越高。针对大型国产火力发电机组,国家制定了完整的污染物排放控制标准,对某国产600 MW亚临界机组进行综合升级改造。改造的主要内容包括在尾部烟道加装SCR脱硝系统、对空预器密封结构及换热元件进行改造及风机"增引合一"改造。同时还完成了汽轮机汽封改造、在空预器出口烟道加装低温省煤器等,此次升级改造能为同类机组提供借鉴。With the development of economy,the society requirements for environmental protection is more and more fervent. In view to the large domestic thermal power plant,our nation has build a complete criteria for pollutants emission control. Sponsored by the National Energy administration,a 600 MW subcritical power plant conducted a comprehensive upgrade. This paper mainly focuses on the improvement of boiler thermal performance after comprehensive upgrade.
