Abstract
A heat exchanger that is universally usable in the flue stack of a heating appliance and yet is efficient and capable of properly matching the rate of heat exchange to the heat rating of the heating appliance. The basic elements of the heat exchanger which affect heat transfer, include the length and diameter of the flue gas tubes, the tube support structure defining the tube spacing, air flow baffles, air openings and the size of the blower are held constant. To match the amount of heat recovery from the flue gas to the heat rating of heating appliance, only the amount of heat exchange surface area (finning) is varied from heat exchanger to heat exchanger. Further, the heat exchanger includes a heat transfer section which is readily separable from the flue gas inlet and outlet assemblies for cleaning or repair without the need for complete removal of the entire heat exchanger from the flue stack.
