| 摘 要： | 利用等效热降法定量分析了汽动给水泵运行特性对机组热经济性所产生的影响。分析结果表明，给水泵汽轮机的运行特性对机组热经济性的影响比给水泵的影响大，且主机负荷越低时，汽动给水泵和给水泵汽轮机效率对机组热经济性的影响越大。

| Abstract: | The influence of the operation characteristics of a steam feed pump set on its thermal economic efficiency was quantitatively analyzed using equivalent enthalpy drop method.The result shows that the influence of the operation characteristics of the steam turbine of the feed pump set on the thermal economic efficiency of the pump set is stronger than that of the feed pump,and the lower the load of the major machine,the higher the influence of the efficiencies of the steam feed pumps and their steam turbines on the thermal economic efficiency of the pump set will become. |
