The invention relates to a method for adjusting deviation of two sides of the reheating
steam temperature of a four-corner
tangential firing boiler by SOFA air
doors. The method for adjusting the deviation of the two sides of the reheating
steam temperature of the four-corner
tangential firing boiler by the SOFA air
doors comprises the steps that horizontal
pendulum angles of the SOFA air
doors are adjusted; when the deviation of two sides of the reheating
steam temperature is removed, vertical
pendulum angles of the SOFA air doors are no longer adjusted; when the deviation of two sides of thereheating steam temperature is not removed, the vertical
pendulum angles of the SOFA air doors are adjusted; and when the vertical pendulum angles of the SOFA air doors are adjusted, firstly, the vertical pendulum angles of a second SOFA
air door and a third SOFA
air door are adjusted obliquely upwards, and then, the vertical pendulum angles of a first SOFA
air door and a fourth SOFA air door areadjusted to horizontal positions. The adjustment of the reheating steam temperature and temperature-decreased
water flow is realized through the cooperative cooperation of the horizontal pendulum angles and the vertical pendulum angles of the SOFA air door, through the nonsynchronous adjustment of the horizontal pendulum angles and the vertical pendulum angles, the deviation of two sides of smoketemperature of the four-corner
tangential firing boiler is rapidly reduced, the high-temperature point of the reheater
pipe wall is reduced, the problems of large deviation of a reheater outlet
stream temperature and the unbalanced temperature-decreased
water flow on two sides are solved, finally, the average
stream temperature of the reheater outlet is improved, and the temperature-decreased
water flow of the reheater is reduced.
