ABSTRACT:
The specification discloses a novel energy saving forced-air furnace. In contrast to previous forced-air furnaces, which ran only on gas or oil and in which approximately half of the energy derived from the burning fuel was lost through the chimney, the furnace of the present invention can run on coal, wood, gas or oil and retains a substantial portion of the heat which normally would be lost by the utilization of special tubing units and refractory plates. My furnace saves the greatest amount of energy possible by providing a heat chamber having a special tubing unit therein from the surface area of which heat generated in a stove chamber is transferred to a heat chamber and simultaneously through which exhaust gases air conducted from the stove chamber mounted below the heat chamber to the exterior of the furnace. Refractory plates are placed in a serial arrangement within the furnace heat chamber with spaces provided between them. The purpose of the spacing between each refractory plate is to allow for efficient air circulation within the furnace heat chamber so that the energy transmitted by the hot gases as they enter the heat chamber via the specially designed tubing unit may be transferred to and stored by the refractory plates during intervals when the blower is not operating and heat drawn from them when the blower is activated. Thus, my novel energy saving forced-air furnace can operate on a steady slow burning fire such as a coal or wood fire, without loss of energy, or use the more conventional gas or oil firing means by drawing heat from the refractory plates after the burner is shut off by the thermostat, until the plates cool, and substantially reduce the amount of energy currently being wasted by conventional modern furnaces.
