Research on Dynamic Characteristics of Furnace in 670 t/h Ultra-high Pressure Pulverized Coal Furnace after Burner Transformation

Abstract

The power field characteristics of a 670t/h boiler in a power plant were studied after the burner transformation. The results show that the size of the aerodynamic fluid in the hearth of the burner is appropriate, the furnace is full, and the center of the strong wind ring is basically in the center of the hearth. The wind speed of the wall around the water-cooled wall is within a reasonable range; there is a certain wind speed deviation on the side, and the angle of the SOFA reverse wind can be adjusted appropriately to eliminate the residual rotation existing at the furnace outlet. The research results can provide a reference for the transformation of burners of the same type.
