Abstract

Abstract: Combining with the practical operation of the 300MW unit of a coalfired power plant, the reasons of lower efficiency of highpressure cylinder in domestic importedtype 300MW steam turbine and typical problems influencing on the unit efficiency were analyzed. A targeted technical improvement scheme was proposed. After the implementation of the improvement scheme, the favorable economic benefit and social effect were obtained.
