【Abstract】 Problems, such as somewhat high main steam temperature, desuperheating water can’t be automatically put into operation, and high exhaust fulegas temperature etc., existing on boiler NO.3 in Dawukow Power Plant , Ningxia Autonomous Regien, influence seriously the economic benavior and safety of the said boler. In this conneation, the heating surface has been adjusted and retrofitted by taking the opportunity of major repair for boiler NO.3 in this power plant.
