Abstract:

Abstract:Under the condition of the high temperature and high pressure,the water cooling membrane walls are apt to corrosion and leakage on the heating surface of them.it was the high temperature corrosion that made the pipe walls reduced,which caused the pipe wall couldn’t resist the pressure and the burst happened.The cause for the corrosion of the pipes was analyzed in this paper.Accordingly,the combustion modes,the coal qualities and boiler improvements were improved.After the improvements above, the leakage of the membrane walls were greatly reduced.

Key words: Keywords:side wind, high temperature corrosion, water cooling membrane wall, reducing atmosphere
