ABSTRACT:
A pellet fuel combustion assembly including a fuel container, an auger for transferring pellet fuel to a burnpot, a top-opening burnpot for receiving the fuel, and an igniter. The burnpot is preferably constructed of insulative ceramic and includes a base portion defining an ignition compartment below the floor of the burnpot. An opening in the floor of the burnpot leads down a ramp to conduct fuel pellets to a position spaced from but closely adjacent the igniter. An air intake port leading into the ignition compartment causes air flow by the hot igniter causing the fuel to ignite by heat conductance as well as radiation. The igniter, once ignition has taken place, is cooled by the air flow and is separated from the extreme temperatures of the combustion chamber by the insulative floor, thus giving a long service life. The combustion assembly may include an air blower for superior combustion and one or more thermocouples positioned over the combustion chamber for controlling activation of the igniter, auger, and blower. The auger features a novel spring type auger member having a diameter substantially less than the feed tube in which it rotates to pull fuel pellets from the container.
