ABSTRACT:
A high efficiency induced draft clamshell type heat exchanger for use in a hot air furnace. The geometry of the heat exchanger is such that the various segments are compactly arranged to transfer heat from the fuel to the air passing over the heat exchanger surface while maintaining the discharged products of combustion at a temperature sufficiently high to prevent condensation from forming or collecting within the heat exchanger during steady state operation.
