Abstract
A gas furnace includes a mixing pipe through which a mixture formed by mixing fuel gas and air flows; a burner assembly that generates combustion gas by burning the mixture that passed through the mixing pipe; and a heat exchanger through which the combustion gas flows. In this case, the burner assembly includes a burner in which flame generated when the mixture is burned is seated; and a mixing chamber that mediates delivery of the mixture from the mixing pipe to the burner, thereby significantly reducing NOx emission.
