    摘要： The invention provides a combustion apparatus which can inhibit an NOx generation even in the case of promoting a mixing between a high-temperature combustion gas and an air so as to intend to reduce an unburned combustible. In a combustion apparatus provided with a burner burning a fuel within a furnace in a theoretical air ratio or less, and an air port supplying a combustion air for a shortfall in the burner, a supply apparatus for supplying a nitrogen oxide generation inhibiting gas is provided in a mixing region between the both or near the mixing region. Further, the invention provides a wind box which can inhibit an NOx generation even in the case of promoting a mixing between a high-temperature combustion gas and an air so as to intend to reduce an unburned combustible. In a wind box having an air port arranged in a back flow side of the burner and supplying a combustion air for a shortfall in the burner, a supply apparatus for supplying a nitrogen oxide generation inhibiting gas is provided in a mixing region between the both or near the mixing region.

    摘要： Provided is a solid fuel burner (60) suitable for controlling a flame to be formed by combustion of fuel ejected from the burner (60) and a temperature distribution in a furnace, a combustion apparatus using the solid fuel burner (60), and a method of operating the combustion apparatus. Providing in the fuel nozzle (10) a plurality of gas ejection nozzles (81), (82) and a restriction (obstacle) (19) downstream thereof, and ejecting a relatively large amount of gas from a portion of the gas ejection nozzles (81) provides a circumferential distribution in fuel concentration. Further, having the restriction (obstacle) (19) on a downstream side increases a deviation in fuel concentration. Providing a fuel concentration deviation in the circumferential direction makes it possible to change the forming position of a flame. Therefore, regulating the flow rate of gas flowing through the gas ejection nozzles (81), (82) makes it possible to control constant the temperature of combustion gas at a furnace exit, the temperature of a heat transfer tube provided on a furnace wall surface, the temperature of a fluid flowing through the heat transfer tube, or the temperature of a heat transfer tube provided in a furnace or at a downstream-side flue portion thereof and the temperature of a fluid flowing through the heat transfer tube.
