The adjustment measures of superheated steam temperature in supercritical boiler are briefly described.

Answer: (1) Adjust the coal-water ratio m. With the increase of coal-water ratio, the superheated steam temperature increases; If the coal-water ratio is reduced, the superheated steam temperature will decrease.

(2) spray water to cool down. The temperature of superheated steam decreases with the increase of water spray; Reduce the amount of water spray and the temperature of superheated steam will increase.

(3) Swing the burner nozzle. The burner nozzle swings upwards, and the temperature of superheated steam rises; The burner nozzle swings downward, and the temperature of superheated steam decreases.

(4) Adjust the combustion zone. Adding burner area in burner area can stabilize combustion, reduce the heat absorption rate of water wall and improve the heat absorption rate of superheater. Reducing the heat absorption rate of water wall will reduce the steam flow of boiler; Increasing the heat absorption rate of superheater will increase the temperature of superheated steam. Removing part of the burner area can improve the heat absorption rate of the water wall and reduce the heat absorption rate of the superheater. Increasing the heat absorption rate of water wall will increase the steam flow of boiler; Reducing the heat absorption ratio of superheater will reduce the temperature of superheated steam.
