| Abstract: | Aiming at the accident of water wall tube explosion causing by high- temperaturecorrosion happening in a boiler of power plant, By the methods of macroscopic inspection,metallographic analysis and sediment energy spectrum analysis, finds out the influence factors of hightemperature corrosion of water wall tubes corrosion, brings forward prevention measure. Theapplication result shows that burner improvement and boiler combustion adjustment can controlavailably the the accident of water wall tube explosion and ensure the safe and steady operation of theboiler. |
