用汽泵替代电泵启动300MW火电机组的节能效果

Energy conservation effect of using steam pump replacing of electric pump to start thermal power generation unit

通过对深圳妈湾电厂机组启动初期上水方式的研究,提出了以汽泵代替电泵完成机组的启动过程的方案,经过实际应用,证实具有显著的经济性。并应用等效焓降法进行了经济性分析,相对于常规的定性分析,使我们不仅看到了节能的方向,更看到了节能方法直接经济效益的大小,从而达到了把等效焓降法在节能方面的应用加以推广的目的。

Through the researches starting initial stage feeding water of ways to Shenzhen mawan power plant unit,Proposed and was substituted by turbine drive feeding water pump the scheme of the start-up course of finishing the unit of motor driver feeding water pump, Through the practical application, verify its remarkable.Use equivalent lower law go on person who help analyses between looks and routine qualitative analysis by enthalpy, Make us not merely seen energy-conserving direction,has seen the size of the energy-conserving method direct even more,Thus achieved and lowered the application in the energy-conserving respect of the law of the equivalent enthalpy and popularized the purpose.
