省煤器改型应用的效果分析

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

针对通辽发电厂3号炉省煤器磨损泄漏问题,分析了磨损原因,并进行了省煤器的改造。改造采取主体不变,改用膜式省煤器的措施来提高受热面的耐磨性。改造后较好地解决了省煤器泄漏问题,提高了锅炉运行的稳定性和经济性。

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.
