Hill, R C

A stove or furnace for efficient combustion of wood fuel includes a vertical feed combustion chamber for receiving and supporting wood fuel in a vertical attitude or stack. A major upper portion of the combustion chamber column comprises a water jacket for coupling to a source of water or heat transfer fluid for convection circulation of the fluid. The locus of wood fuel combustion is thereby confined to the refractory base of the combustion chamber. A flue gas propagation delay channel extending laterally from the base of the chamber affords delayed travel time in a high temperature refractory 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. Induced draft draws the fuel gas and air mixture laterally through the combustion chamber and refractory high temperature zone to the heat exchanger and flue. Also included are active sources of forced air and induced draft, multiple circuit couplings for the recovered heat, and construction features in the refractory material substructure and metal component superstructure.
