するボイラ装置。A combustion air system that supplies combustion air to the boiler burner, an exhaust gas recirculation system from the boiler outlet to the bottom of the furnace, and an exhaust gas mixing system between the exhaust gas recirculation system and the combustion air system are installed to prevent exhaust gas mixing. The amount of exhaust gas in the system is maintained at a constant level by a damper, and the amount of exhaust gas in the exhaust gas recirculation system is increased or decreased by a variable damper. A boiler device characterized in that the amount of exhaust gas is always greater than the amount of exhaust gas input from the exhaust gas recirculation system to the bottom of the furnace.
