Abstract:There appeared pipeline leakage and crack in the tower boiler water wall of 1000 MW ultra-supercritical coal-fired power generating units after the units had been put into operation for a period of time. The problems are analyzed and the countermeasures put forward could eliminate the water wall leakage hidden troubles in a timely manner on the basis of fully considering the peculiarity of T23 steel tubes performance. Some solutions to similar problems are offered for references.
