| Abstract: | NG-901FA-R exhaust heat boilers,produced by Hangzhou Boiler Plant,are used as part of No.1、No.2、No.3 gas-fired generating units in Hangzhou Banshan Power Generation Co.Ltd.If the high pressure of superheat is more than 2,cracks may occur in welding joints of tubes,which lead to leakage and cause unplanned tube replacements.Based on the analysis of reasons due to cracks in heat exposure module,several solutions are proposed and the practical feasibilities are described. |
