125MW抽汽凝汽式机组改造为背压机组的可行性分析

Feasibility Analysis on Changing 125MW Extraction Condensing Turbine into Back Pressure Steam Turbine

介绍某电厂125MW抽汽凝汽式汽轮机组概况,提出在基础系统及辅机等不变的前提下将该机组改造为背压机组的思路及要求,阐述汽轮机可采取的改造方案,通过分析改造后机组性能会发生的变化及改造效益,认为将125MW抽汽凝汽式机组改造为背压机组具有可行性。

This paper introduces the 125 MW extraction conden- sing steam turbine,presents the reform thought and principle of changing 125 MW extraction condensing turbine into back-pres- sure steam turbine on the basis of basic system and auxiliary e-- quipment,expounds that reform project, considers that it is the feasibility that 125 MW extraction condensing steam turbine is changed to back-pressure steam turbine through analysis on the characteristic changes and the reformation benefits.
