摘要

采用给水泵汽轮机驱动给水泵

可以减少节流阀的压力损失

且给水泵汽轮机排汽还可用于除氧器加热

从而可提高火力发电厂的经济性。给水泵汽轮机采用变转速调节

其与给水泵之间的能量转换效率更高。同时

给水泵变速运行使锅炉给水系统运行更加安全可靠。

Abstract

Using small turbine to drive a feed-water pump

the pressure loss of throttle valve can be decreased

the exhaust steam from said samll turbine can also be used for heating in the deaerator

thereby enhancing the economic efficiency of thermal power plant.The variable speed adjusting function of said small turbine makes the energy conversion efficiency between said small turbine and the feed-water pump to be more higher

at the same time

the variable speed operation of feed-water pump makes the operation of boiler's feed-water system to be more safe and reliable.
