Pulverized coal sorting device in thermal power generation pulverized coal burner and using method

Abstract

The invention discloses a pulverized coal sorting device in a pulverized coal burner for thermal power generation and a using method, and belongs to the technical field of burners, the pulverized coal sorting device comprises a burner body and a main box body, the main box body is connected with a pulverized coal conveying pipe of the burner body, and a screening assembly, a baffle moving assembly and a transmission assembly are arranged in the main box body; pulverized coal enters from the conveying port of the main box body and then is separated into large-particle pulverized coal and small-particle pulverized coal through screening, the small-particle pulverized coal is conveyed into the pulverized coal conveying pipe of the burner body, and the large-particle pulverized coal is collected. The large-particle pulverized coal and the small-particle pulverized coal can be thoroughly separated out, the probability that the small-particle pulverized coal is taken out by the large-particle pulverized coal is reduced, and therefore screening thoroughness and working efficiency are improved.
