Fireside corrosion has not been a severe problem in Danish power plants. Furnace wall corrosion has only been seen in one unit caused by insufficient control of the burners. High temperature corrosion has only been seen in units, where the final stage of superheater/reheater was placed in gas temperatures above 1300°C or where the difference in tube length was too big. Since 1970 the final stages of superheater and reheater are made of X20 CrMo V 12.1, which has showed excellent behavior. For estimation of the remaining service life of superheater/reheater, they are examined after 100,000 h in service.
