Abstract

A fuel-fired, condensing type forced air heating fur-nace is provided with an improved hot combustion gas-to-air heat exchange system which includes a generally drum-shaped primary heat exchanger having an outlet end connected to a first end of a transfer manifold whose second end is connected the inlet end of a fin-and-tube type secondary heat exchanger which is spaced laterally apart from, faces, and extends generally parallel to the primary heat exchanger. A radial discharge fuel burner end portion is coaxially positioned within an inlet end of the pri-mary heat exchanger and, during furnace operation, a draft inducer fan draws burner combustion gases sequentially through the primary heat exchanger, the transfer manifold and the secon-dary heat exchanger while air to be heated is flowed externally over these heat transfer elements. The overall heating effi-ciency of the furnace is improved, and the fabrication cost of the furnace is reduced, by the use of the radial discharge burner, a perforated baffle wall which improves the air heating capacity of the manifold, and a weldless mechanical crimp roll joint construction used to fabricate and interconnect the primary heat exchanger and transfer manifold.
