| Abstract: | According to the characteristics of throttle orifice of vertical tube ultra super critical boiler, combined with the actual operation status of 3ingdezhen 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. |
