Analysis of Reducing High Temperature Corrosion by Air Distribution Optimization after Transformation of Secondary Bellows
In order to meet the ultra-low emission,a W-flame boiler unit in Guizhou has carried out low-nitrogen combustion transformation.The boiler burner to the over fire air area is often in a local anoxic combustion state,and the high-temperature corrosion of the water-wall is serious.In order to solve the problem of local anoxic combustion and high temperature corrosion of water wall,the plant has carried out the transformation of secondary bellows separation,and carried out the optimization test of air distribution.After the transformation of the secondary bellows,the air distribution optimization test ensured that the air pressure of each bellows was basically the same,solved the problem of local anoxic combustion of the water wall in the area from the burner to the over fire air,improved the reducing atmosphere in the area of the water wall,and slowed down the high temperature corrosion of the water wall.
