To improve combustion and prevent hazardous materials from being discharged by supplying additional air uniformly to the whole surface of a furnace of inverted boiler equipment, and accelerate air diffusion in the furnace.
In the inverted boiler equipment, an air box provided with fuel nozzles and main air nozzles are placed on the top of a boiler main body, additional air nozzles are provided below the air box, and an outlet of burnout gas is provided in the lowest part of the boiler min body. The additional air nozzles of different air-jetting modes are arranged in a plurality of stages in the direction of the height of the boiler main body. Among the additional air nozzles, nozzles in the upstream stage are arranged so as to jet additional air to the part close to the furnace wall in the furnace, and the nozzles in the downstream stages are arranged so as to jet additional air to the part closer to the center than the nozzles in the upstream stage.
