摘　　要：对超临界600 MW抽汽供热汽轮机组应用于工业供热的安全性和经济性进行了分析。以某同容量等级超临界纯凝汽轮机为原型机,通过对中压内外缸、中压末二级叶片、联通管、低压末级叶片等处结构进行改进,可实现抽汽供热的功能,满足近、远期用热需求。The safety and economic efficiency of using supercritical 600MW extraction steam turbine for heating in industry have been analysed. Taking identical capacity - level supercrtical pure condensing steam turbine as prototype turbine, through retrofit of the medium - pressure final two - stage blades, the crossover pipe, and the low - pressure final - stage blades etc. , the function for extracting steam and for heating has been realized. After retrofit and application,it can satisfy the heat demand in short and long terms.
