摘　　要：以国内某电厂三期扩建2×350MW等级汽轮机发电机组的方案为例,拟在热电联产工程背凝式机组进行3S离合器的应用,分析了拟采用方案的经济性,说明了3S离合器连接高中压缸和低压缸的技术方案。通过计算说明,用该方案,将可提高主机的热效率,并降低机组的煤耗。Taking the extension of 2x350MW stage steam turbine generator set in the third phase of a domestic power plant as an example, the application of the 3S clutch to the back condensing unit of the cogeneration project is proposed, and the economy of the proposed scheme is analyzed. The technical scheme of connecting high and low pressure cylinder with 3S clutch is introduced. The calculation shows that the thermal efficiency of the main engine can be improved and the coal consumption of the unit can be reduced by using this scheme.
