A new and improved stove or furnace for efficient combustion of wood or other solid fuel including a vertical feed combustion chamber (15) for receiving and supporting fuel in a vertical attitude or stack, a major upper portion of the combustion chamber column comprising a water jacket (14) for coupling to a source of water or heat transfer fluid and for convection circulation of the fluid. The locus (31) of wood fuel combustion is confined to the base (30) of the vertical gravity feed combustion chamber. A flue gas propagation delay channel (34) extending laterally from the base of the chamber affords delayed travel time in a high temperature environment sufficient to assure substantially complete combustion of the gaseous products of wood burning with forced air prior to extraction of heat in heat exchanger (16). Induced draft draws the fuel gas an d air mixture laterally through the combustion and high temperature zone. Active sources of forced air (36) and induced draft (38) are included, multiple use circuit couplings for the recovered heat, and construction features in the refractory material substructure (12) and metal component superstructure. |
