Abstract
A combustion gas furnace includes a plurality of primary heat exchangers for passage of combustion gases therethrough. A plurality of secondary heat exchangers receive the combustion gases from the primary heat exchanger. Each of the secondary heat exchangers includes a heat conductive element defining a plurality of elongate passageways for the flow of combustion gas therethrough. The passageways include aligned ports at either end thereof. The passageways are generally aligned and separated by longitudinal walls extending between the ends. The walls are positioned for heat conductive contact with the combustion gases flowing through passageways.
