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.
Claims8
In a furnace,
- a pot with an open top for holding fuel during the burning process,
- an elongate tube connecting at the outfeed end thereof with the interior of the pot and extending laterally therefrom, and an elongate rotatable auger extending within the tube for moving fuel along the length of the tube and thence into the pot,
- perforate means formed in the side of the pot, and
- air-flow-producing means including power-driven blower means, structure connecting with said blower means producing air flow by the blower means from outside the perforate means and through the perforate means to the pot interior for supporting combustion, and structure connecting with said blower means producing air flow by the blower means through said tube and out the outfeed end thereof to further support combustion and to inhibit reverse air flow through the tube.
A furnace comprising
- a pot with an open top for holding fuel during the burning process, an elongate tube connecting at the outfeed end thereof with the interior of the pot and extending laterally therefrom and an elongate rotatable auger within the tube for moving fuel along the length of the tube into the pot,
- said tube having an infeed end and an entrance facing upwardly at its infeed end which provides for gravity flow of fuel from the entrance onto the auger extending below the entrance,
- a rotatable metering wheel for feeding metered amounts of particulate solid fuel spaced above said entrance in a relationship whereby fuel free-falls from the metering wheel into said entrance, and
- powered means for rotating the auger and metering wheel at relative speeds whereby the carrying capacity of the auger exceeds the carrying capacity of the metering wheel.
