Problems and Diagnosis of Condensate Polishing System in Ultra-Supercritical Power Plant

Abstract

Aiming at dealing with the problems of design, debug, and operation that occurred in the condensate polishing system, the paper put forward the problems of the high concentration of oxygen at the outlet of the condensate pump, pollution of the prefilter, the presence of remaining resin in the upper water cap of the high speed mixed bed, condenser leakage and abnormal shutdown of the turbine through the data analysis of condensate polishing system in Taishan Power Plant, diagnostic analysis of all these problems was performed and appropriate solutions were put forward.
