ANALYSIS OF AND STUDY ON RETROFIT AND APPLICATION RESULT OF ECONOMIZER IN THERMAL POWER PLANT

Jingrong Zhang

Abstract

Directing against problems of wornout and leakage on economizer of boiler no3 in Tongliao Power Plant, the causes leading to wornout have been analysed, and retrofit of said economizer being carried out. In retrofit, measures of not varying the main body and changing over to use membrane economizer for enhancing wearresistant capability of the heating surface have been taken. Analysis of test results after retrofitting shows that the said retrofitting is successful, having solved the existing problems of leakage, enhancing the stability and economic behavior of the said boiler.
