摘要
基于能量价值分析计算方法,阐述了给水泵两种不同驱动方式下输出净功率、供电煤耗率、综合煤耗率的3种计算方法,并根据华能东方电厂350 MW机组在日常调峰范围内不同运行方式下的参数,应用3种方法进行了定量分析计算,得出对于调峰负荷在50%～100%情况下的350 MW新建火电机组,采用汽动给水泵方式具有更好的经济效益,给同类型机组给水泵驱动方式的选取提供了借鉴依据。
Based on energy value analysis method, by using two different driving modes for feed water pumps, three methods are presented to calculate net output power, coal consumption rate of power supply and integrated coal consumption rate. According to the different operation parameters within the load range of Huaneng Dongfang 350 MW unit, the three methods are applied to conduct quantitative analysis and calculation. It is concluded that the steam turbine-driven feed water pump is better than the electric feed water pump within the peak load range of 50% - 100% for a new 350 MW unit. The studies provide reference in selecting driving modes of feed water pumps for similar units.
