Abstract

Provided is a combustion burner including: a fuel nozzle (51) that is able to blow a fuel gas obtained by mixing pulverized coal with primary air; a secondary air nozzle (52) that is able to blow secondary air from the outside of the fuel nozzle (51); a flame stabilizer (54) that is provided at a front end portion of the fuel nozzle (51) so as to be near the axis center; and a rectification member (55) that is provided between the inner wall surface of the fuel nozzle (51) and the flame stabilizer (54), wherein an appropriate flow of a fuel gas obtained by mixing solid fuel with air may be realized.
