Research on Efficient and Economic Operation of Steam-Driven Feed Pump for 1 Million kW Secondary Reheating Unit
The configuration of 1×100%BMCR capacity for the feed water pump of a million-kilowatt secondary reheating unit has become the mainstream configuration.This article introduces the current configuration status of the feed water pump of a million-kilowatt secondary reheating unit and the ab-normal fluctuations in feed water flow at low and medium load sections.This paper analyzes and stud-ies the causes of the fluctuations,and proposes renovation measures to provide ideas and references for solving such problems.
