Lemon, W T

A wood burning heating unit capable of being stoked for continuous or extended burning, and of achieving effective combustion of volatiles contained in the smoke is provided. The stove body, a generally cylindrical casing, is supported so that its axis is substantially horizontal. A baffle divides the casing into a fire box or combustion chamber and an exhaust chamber which functions as a heat exchanger. The exhaust chamber is vented to the outside atmosphere by an exhaust conduit or flue pipe. A pair of elongate, fuel feed conduits extend downwardly and inwardly into the fire box or combustion chamber, so that respective, generally upstanding columns of logs can be formed in the fuel feeding conduits with the lower ends of the wood log columns contacting each other to define and limit the area of combustion in the fire box. Manifold means is provided for drawing combustion air from outside the stove body, passing the air through a heat exchange area in the manifold adjacent to the combustion zone for preheating the combustion air, and then supplying the heated air into proximity of the contact between the two columns of logs.
