| Abstract: | Tne overall checking and testing of the lose effectiveness heat exchanger are carried out by the authors. The crack and break of the shell, tubes and the tightened bolt are caused by brittleness break along grain boundary which are deduced by stress corrosion, when high temperature cycle warer contained carbonate is used in the heat exchanger. Some improved methods are present in this paper. |
