中小型热电厂锅炉给水泵常见故障原因与对策

Generic Faults of Boiler Feed Water Pumps,Observed in Cogeneration Power Plants of Small and Medium Capacity——Cause and Countermeasures

近年来,各地新建了一批热电联产的发电机组,用来取代原有的供热锅炉,但部分机组锅炉给水泵存在一些问题,对安全、供电、供热都带来不利影响。对一些常见的设备缺陷进行了分析,并提出对策。

In the past few years, a number of new heat-power cogeneration sets have been constructed, to replace heating boilers＇ used originally, but some of them were troubled with feed water pump problems, which endangered safe delivery of both power and heat. Equipment deficiencies, often met with, are being analyzed and remedies recommended.
