In order to analyze the reason of the boiler\'s water wall tube bursting,macrostructure,chemical composition check,metallographic check,tensile testing at ambient temperature and other tests are made,and the results are indicated that the high temperature steam corrosion and hydrogen damage of the rough tube wall which was caused by overheating welding is the main cause of the tube bursting.

Investigations on outer thermal spraying and inner shot blasting on boiler tube to promote high-temperature corrosion resistance;

The large amount of vanadium in Orimulsion may cause unexpected problems in the prevention of high-temperature corrosion of furnace.

The mechanism of high-temperature corrosion on water-wall of coal-fired boilers in thermal power plants has been briefly presented, and preventive countermeasures being put forward directing against different causes of high-temperature corrosion, the prevention technology of spraying corrosion-resistant metallic coatings onto surface of the water-wall being emphatically narrated.
