中小热电厂改用汽动给水泵的经济效益分析

Economic benefit analysis on small and middle thermal power plants using steam-driven feedwater pumps

中小热电厂给水泵拖动方式多数采用电动方式,个别采用汽轮机拖动。论述了利用锅炉富余蒸汽或工业抽汽驱动小汽轮机拖动给水泵,排汽进入除氧器作加热蒸汽,可以提高经济效益或节能效益。

The feed water pump in the medium or small hot power station drags mainly adopting the dynamoelectric way,individually adopting turbine to drag.It raises the economic performance or economizes on energy to make use of the boiler waste steam or industrial extraction steam to drive a small turbine to drag feed water pump and the exhaust steam enter deaerator as heating steam.This article discusses the problem hereinbefore,which is only to be consulted.
