According to the characteristics of throttle orifice of vertical tube ultra super critical boiler

combined with the actual operation status of Jingdezhen power plant

the causes of boiler water wall and reheater tube wall temperature deviation were comprehensive analyzed. The influencing factors of grinding group mode of operation

the air distribution on the temperature of the heating surface were analyzd. By adjusting the flue gas side temperature

reduce the exit flue gas temperature deviation in the furnace and furnace

the heat evenly

effectively reducing the temperature of the heating surface deviation

creating favorable conditions for the long term stable operation.
