Analysis on reformation of backwater recovery device of sealing water for feed pump of 135MW turbine

Abstract

Abstract: Abstract:Taking the 135MW unit of Huadian Xinzhou Guangyu Coal and Power Company Limited as example, the problems existing in the spiral sealing structure adopted in shaft end seal of the feed pump set were introduced. A targeted reformation scheme was proposed, and the application scope of the scheme was given. The economical benefit and the social effects of the reformation were analyzed, and the result in this paper shows that the scheme has good promotion prospects.

Key words: Keywords:thermal power plant, feed pump, sealing water, backwater recovery, benefit analysis, water conservation
