    Abstract: Disclosed is a gas furnace including a mixer configured to mix air and fuel gas introduced from an intake pipe and a manifold respectively so as to produce an air-fuel mixture, a mixing pipe configured to allow the air-fuel mixture having passed through the mixer to flow therein, a burner assembly configured to combust the air-fuel mixture having passed through the mixing pipe so as to generate combustion gas, heat exchangers configured to allow the combustion gas to flow therein, an exhaust pipe configured to discharge exhaust gas, which is the combustion gas having passed through the heat exchangers, to the outside. The gas furnace further includes a recirculator installed around the exhaust pipe and configured to guide a portion of the exhaust gas flowing in the exhaust pipe to the mixer, and may thus greatly reduce or fundamentally block NOx emissions.

    Abstract: Provided is a condensate water trap for a gas furnace that collects and discharges condensate water produced in a heat exchanger and an exhaust pipe. The condensate water trap includes: a first inlet through which the condensate water produced in the heat exchanger is introduced; a second inlet through which the condensate water produced in the exhaust pipe is introduced; a first flow path through which the condensate water coming from the first inlet passes; a second flow path through which the condensate water coming from the second inlet passes; an outlet through which the condensate water introduced through the first and second inlets is discharged; a third flow path into which the residual condensate water passed through at least one of the first and second flow paths but not discharged through the outlet is introduced; and a sensing mechanism that senses if the amount of residual condensate water introduced into the third flow path is greater than or equal to a given amount.
