ABSTRACT:
A pellet burning heating device (20) designed to operate at a combustion efficiency of about 90-98% (based on the oxygen-derived combustion efficiency formula), and to emit exhaust gases having a carbon monoxide concentration, by volume, of about 0.04% or less, which device does not incorporate a fan system for introducing combustion air into, or extracting exhaust gases from, the stove. High combustion efficiency and clean burning are accomplished by providing a plurality of apertures (130, 132) in the burn pot (120) of the device having a predetermined size, number, and placement. The heating device (20) also includes an aperture (200) which provides a wash of relatively cool air to the inside surface of the window in order to reduce carbon deposits. A shaker (160) located in the burn pot (120) provides a heat sink which helps to increase the efficiency of the heating device. In addition, a drop chute (214) located in between the feed assembly (60) and the combustion flame (154) prevents the possibility of any back burn of the combustion flame into the pellet hopper ( 40).
