Abstract: during the high load phase of unit 3 of Bengbu Power Plant of state power grid, the superheat of unit, the abnormal temperature of main reheat steam, the frequent deviation between the actual pressure of main steam and the target pressure occurred, which seriously affected the safe operation of unit. This paper analyzes the parameters, operation and the selection of superheat degree of the boiler in the start-up stage of the unit, and gives targeted optimization suggestions and preventive measures to improve the stability and safety of the unit operation.<br>
