A combustion burner includes a mixture nozzle (,) defining a mixture fluid passage through which a mixture fluid (,) containing pulverized coal and conveyor gas flows toward a furnace, secondary and tertiary air passages surrounding the mixture nozzle (,), through which secondary air (,) and tertiary air (,) for combustion purposes flow, respectively; and air injection nozzles (,) provided in the vicinity of an outer periphery of a distal end of the mixture nozzle (,). The air (,) is injected from the air injection nozzles (,) toward the axis of the mixture nozzle, so that the high-temperature gas in the vicinity of the outer periphery of the distal end of the mixture nozzle (,) is drawn into the mixture fluid (,) in the vicinity of the outer periphery of this distal end.
