道装置。 In a boiler air duct system in which an air/gas mixer is provided in the middle of a main air duct that supplies combustion air to a boiler furnace, an overfire air branch is provided from the upstream portion of the air/gas mixer in the main air duct. Bypassing the air/gas mixer, the fresh air duct for the main air duct is guided into the downstream part of the air/gas mixer in the main air duct, and is inserted through this main air duct to communicate with the boiler furnace. A boiler air duct device characterized by:
