| Abstract: | In this paper the formation mechanism and conditions of high temperature corrosion of wa ter-cooled wall tube in large boilers are discussed.The re search results show that the corrosion is mianly caused by high tem pera ture sulfur cor rosion in lean coal burned boiler,and the corrosion situation in three kinds of combustion furnace is dif fer-ent.As well as the corrosion can be protected by improving com bustion technology. |
