摘要:
The burner device for high-temperature air combustion according to the present invention is equipped with a thermal insulation portion (5) that is provided facing a furnace (1) and has a throat (6); a burner nozzle (9) that is provided at the axial center of this throat and that injects a pulverized coal mixed flow (38) into the furnace through the throat; a windbox (8) that is provided so as to house this burner nozzle; an air register (16) that is provided at the distal end of the burner nozzle and that injects low-temperature secondary air from the windbox to the throat; a high-temperature air nozzle (23), one end of which opens into the furnace through the heat insulation portion; and a combustion air switching means (16, 24) that switches between injecting low-temperature secondary air to the throat through the air register and injecting high-temperature secondary air to the furnace interior through the high-temperature air nozzle, in which in steady combustion, low-temperature secondary air is injected to the throat through the air register by the combustion air switching means and a pulverized coal mixed flow is injected from the burner nozzle, and in high-temperature air combustion, high-temperature secondary air is injected to the furnace interior through the high-temperature air nozzle by the combustion air switching means and a pulverized coal mixed flow is injected from the burner nozzle.
