ABSTRACT:
A solid fuel combustion assembly for use with pellet fuel and having a hopper; an auger within an auger tube for receiving fuel from the hopper and conveying it to a burnpot; a burnpot having a tubular fuel conduit fed by the auger at one end and terminating in a top opening to define a primary combustion chamber at the other; and a dome, with or without a top opening, mounted over and about the fuel conduit to define a secondary combustion chamber. A jacket surrounding the auger tube and the fuel conduit defines an air chamber having an opening to atmosphere, adjacent the auger. A plurality of peripherally spaced apertures opening into the fuel conduit from the air chamber, adjacent the top opening of the fuel conduit, provides a primary air source for the primary combustion chamber and a plurality of like apertures, opening through the jacket and under the dome provide a secondary air source of the secondary combustion chamber. A reactor plate mounted over the dome, when the dome is provided with a top opening, assists in secondary combustion.
