摘　　要：针对目前运行的机组过热器减温水系统原设计布置不合理的问题,以某电厂600 MW机组为例,对机组经济安全进行了可行性分析,最后提出了将过热器减温水取水点由给水泵出口改至高压加热器出口的改造方案。实践表明该改造方案可有效提高机组运行的经济性,可为今后类似机组的改造提供参考。In view of the unreasonable original design layout of the superheater desuperheater water system of the currently operating unit,a feasibility analysis was carried out on the economic safety of the unit with a 600 MW unit in a power plant.The modification plan to change to the outlet of the high-pressure heater shows that this modification plan can effectively improve the economic efficiency of the unit operation,and can provide a reference for the modification of similar units in the future.
