摘要
介绍了华能淮阴电厂330 MW机组电动给水泵改造为汽动给水泵的特点,根据改造后机组在日常调峰范围内不同运行方式下的参数,对改造后的经济性进行了计算,得到机组负荷投资收益表,继而根据该厂实际情况计算了机组投资回收年限,并从机组剩余寿命角度出发对改造的经济性进行了分析,给同类型机组汽动给水泵改造的可行性分析提供借鉴。
This paper introduces the characteristics of replacement of the motorized feedwater pump with the steam turbine-driven feedwater pump in a 330 MW unit. Calculation of the economical efficiency of the renovation is conducted according to the different operation parameters within the load range of operation to obtain the return sheet of the investment in the unit capacity, and then the number of years of investment return is calculated based upon the actual operation conditions of the power plant. The economical efficiency of the upgrading is also analyzed in the light of the remaining service years of the unit. The studies in this paper provide reference for the feasibility study of the feedwater pump renovation for similar units.
