The configuration and layout analysis of large thermal power plant feedwater pump set

Abstract

Abstract:

The different choice of configuration, driving device, control method and the layout of large thermal power plant feedwater pump sets, would form the different influence to the auxiliary power, auxiliary power consumption. This article through the comparing technical and economic of feedwater pump set configuration scheme, both domestic and overseas as well as the actual work, analysis and put forward that a single 100% capacity turbinedriven feedwater pump for daily running configuration, coaxial ectopic layout of small steam turbine using double output shaft to drive feedwater pump and booster pump, is the more reasonable configuration and the layout of feedwater pump set.

Key words:

power plant, steam and water system, feedwater pump, turbinedriven feedwater pump, motordriven feedwater pump, booster pump, energysaving and costreducing, variable speed adjustment
