ABSTRACT:
A fireplace furnace for the hot air heating of a room is disclosed. The fireplace furnace in a particular embodiment has an enclosed primary combustion chamber and a primary air supply for the initial burning of the fuel. A separate enclosed secondary combustion chamber and a secondary air supply for burning the volatiles remaining in the flue gas generated by the primary combustion chamber is also provided. The secondary combustion chamber is located between the primary combustion chamber and an enclosed room air heating chamber. The flow of the air in the room air heating chamber is counter to the flow of the flue gas in the secondary combustion chamber. With this construction, the heat transferred to the room air is from the flue gas of the secondary combustion chamber and none of the heat transferred to the room air is transferred directly from the primary combustion chamber.
