| Abstract: | A boiler has undergone comprehensive upgrading,including low-nitrogen burner rectification,energy-saving and emission reduction,causing the results that the boiler operating condition deviates greatly from the designed value and severe overtemperature of the heating surface wall of the low-temperature and rear-plate superheaters and so on.Based on a statistical analysis of overtemperature point and overtemperature time,rectification measures are put forward. |
