摘　　要：针对纯凝汽式汽轮机原来设计、制造技术落后、实际运行效率低、煤耗高的现状,为实现节能减排的目的,采用先进的全三维技术对其通流部分进行改造和汽缸打孔抽汽,消除了设备隐患,且机组具有灵活的热电联产性能。The traditional straight condensing turbine possesses some defects such as backward in technique,low running efficiency and high coal consumption.In order to realize energy conservation and pollution emissions reduction,advanced full three-dimensional technology is used to transform its venting part and cylinder air-bleed hole.These transformations can not only avoid accidents but also possess flexible combined heat and power generation performance.
