Abstract:
A combustion system for burning solid fuels, comprising:a primary combustion chamber defined by a firebox floor, side walls and a ceiling;fuel retaining standards dividing the primary combustion chamber into separate sections;a canyon having a first end and a second end, the canyon being located within the primary combustion chamber and being defined by at least one fuel retaining standard, the first end of the canyon being proximate to the firebox floor;an air delivery system being positioned proximate to the first end of the canyon, anda lower air tube having a plurality of holes positioned proximate to the firebox floor, the holes of the lower air tube are low velocity holes and high velocity holes, the high velocity holes are directed towards the solid fuel in the first and second section of the primary chamber and the low velocity air tubes are directed substantially within the canyon,wherein the fuel-retaining standards and the firebox floor direct the burning solid fuel toward a bottom of a canyon while retaining non-burning solid fuel outside the chamber in order to prevent quenching and smothering of the combustible gases within the canyon,wherein the canyon permits flames to travel substantially unimpeded from the firebox floor of the primary combustion chamber to the ceiling of the primary combustion chamber.
