Pellet burning system

An apparatus for burning pelletized fuel, comprising:

• a furnace housing means having a heat exchanger means, an exhaust gas flue means and an ash collecting bin therein;
• a burn chamber in said housing above said ash collecting bin, said heat exchanger means being oriented in heat exchanging relation to said burn chamber and intermediate said burn chamber and said flue means;
• a conduit extending through a wall of said housing means and terminating at an end in said burn chamber, said conduit being inclined to the horizontal;
• shaft means and means for supporting said shaft means for rotation;
• a burn basket in said burn chamber and having a bottom wall, a perforate side wall and an open top, said end of said conduit in said burn chamber terminating adjacent said open top and spaced from said bottom wall;
• means for securing said shaft means to said burn basket and for rotation with said shaft means;
• drive means for driving said shaft means for rotation;
• a closed housing means connected to an end of said conduit remote from said end in said burn chamber;
• a fan means for delivering air to said closed housing means and thence to said conduit;
• a storage means for storing pelletized fuel;
• a pelletized fuel feeding means for delivering said pelletized fuel from said storage means to said closed housing means, said inclined relation of said conduit causing said pelletized fuel to move from said closed housing means down said conduit under the influence of gravity and drop into said burn basket;
• and
• control means for regulating the volume of air delivered to said conduit and thence said burn chamber and for regulating the volume of pelletized fuel per unit of time also to said conduit, said air serving to provide the requisite support for sustained ignition and burning of said pelletized fuel in said burn basket as well as preventing a backfiring or burning of said pelletized fuel in said conduit.
