ABSTRACT:
A compact, high efficiency condensing furnace includes a combustion chamber and a pair of radiators. The temperature of the combustion gases is reduced in one of the radiators to the point at which combustion products condense, thereby extracting the latent heat of vaporization from these combustion products. Each of the radiators has an inlet and an outlet and a baffle between the inlet and outlet to prevent combustion gases from passing directly from the inlet to the outlet. Additional turbulence-providing baffles can be provided within the radiators if desired. A combustion air inlet pipe extends through a recess in the bottom of each radiator to the combustion chamber, and a gas burner tube extends generally concentrically within the combustion air inlet pipe to provide a gas flame within the combustion chamber. A flame spreader plate directs the flame toward the bottom of the combustion chamber.
