ABSTRACT:
A furnace which includes a furnace chamber and a fire pot within the chamber for burning solid fuel fed into the fire pot. The fuel is introduced to the fire pot by traveling through a feed tube which extends into the furnace chamber. An air flow is produced for supporting combustion which flows from a chamber defined about the fire pot into the fire pot and also flows through the feed tube effectively to prevent smoke back flow. A metering wheel supplies the solid fuel which is burned from a hopper and this metering wheel, together with an auger which moves fuel through the feed tube, are organized and arranged in such a manner as to eliminate hazardous back burning of fuel.
