采用等效热降理论，对哈尔滨汽轮机厂制造的300 MW亚临界直接空冷机组电泵改为汽泵可行性进行了探讨。分析计算结果表明，电泵改汽泵后供电煤耗降低幅度较小，经济效益不明显，在短期内设备投资无法收回。

In this paper,equivalent enthalpy drop theory was adopted to analyse the feasibility of replacing electric pump with steam feed water pump for 300 MW subcritical direct air cooling unit manufactured by Harbin Steam Turbine Company. The analysis results show that the coal consumption after the reformation reduced not obviously so that the cost in the reformation can not be recovered in the short term.
