Abstract

Abstract:

In recent years,600MW supercritical coalfired units used steam pumps to replace the electric pump in the water supply so as to excavate the potential of the unit. Taking Guangdong Zhuhai Jinwan Power Generation Company Limited as an example, this paper analyzed and summed up the problems encountered during the startup of this mode, and put forward the countermeasures to provide a reference for the successful implementation of steam pump replacing the electric pump in the same type of units.

Key words:

supercritical unit, coalfired unit, steam pump, electric pump, unit potential tapping, startup problem, countermeasure
