Robertson, R L

A solid fuel conversion furnace for breaking down solid fuel into its two basic combustible components, combustible gases and combustible solids, prior to ignition, is described. This is achieved by preheating the solid fuel when it is not in the presence of a combustion supporting atmosphere. This preheating of the solid fuel is achieved through the use of a heat exchange compartment where the hot exhaust gases transfer their heat through the heat exchange wall to preheat the solid fuel in the fuel compartment. The hot exhaust gases are obtained from the ignition of the combustible gases and the combustible solids in the presence of oxygen. This ignition occurs in the fire box area which is below the fuel compartment. The combustible solids are gravity fed to the fire box and the combustible gases are fed to the fire box by both their self-generated pressure and the furnace exhaust draft. 6 claims, 10 figures.
