    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： The present invention provides a solid fuel burner, which, while rendering the capacity larger than that in the conventional art, can suppress an increase in an unignited region and thus can realize the prevention of an increase in NOx concentration in a combustion gas and the prevention of a lowering in combustion efficiency, and a combustion equipment and boiler including the burner. The burner includes a fuel-containing fluid supply nozzle (12) which supplies a fuel-containing fluid, from a connecting part in a fluid transfer flow passage (10) for transferring a fuel-containing fluid including a fuel and a medium for transfer of the fuel, toward an outlet part provided on the wall of a furnace (4). The fuel-containing fluid supply nozzle (12) in its cross section perpendicular to the direction of flow of the fluid is in a rectangular, elliptical, or substantially elliptical form having major and minor axis parts from a connecting part (10a) in the fluid transfer flow passage (10) toward the outlet part provided on the wall surface of the furnace (4). Further, the area of a cross section perpendicular to the direction of flow of the fluid is gradually increased from the connecting part in the fluid transfer flow passage (10) toward the outlet part. One or more air supply nozzles (15) for supplying combustion air are provided on the outer peripheral part of the nozzle (12).
