ABSTRACT:
A pellet stove has an arrangement for improving the flow of air therethrough. Air entering the stove is split into first and second portions. The first portion is diverted upwardly through a combustion chamber, wherein pellets are burned, thereby aiding in the burning of the pellets. The first portion of air then exits from the combustion chamber. It is directed to a rear of the stove through a heat exchanger where a flue exhaust is located. The second portion of air has three parts. The second portion of air is simultaneously diverted upwardly around the hopper and auger mechanisms, whereby the mechanisms and the pellets therein are cooled. One part of the second portion of air then is received in the flue exhaust so that this one part of the second portion of air exits the stove, creating a negative pressure in the combustion chamber. This negative pressure creates a push-pull system effect that improves the draft and pulls the flow of the first portion of air through the combustion chamber wherein the pellets are efficiently burned. Another second part of the second portion of air is heated over the combustions area's top wall and via heat exchange near the exhaust gas from the first portion. This remainder of heated fresh air is fed into the room. A final third part of the second portion is pushed into the combustion chamber via the auger feed mechanism, precluding heat build-up. The improved air flow permits the device to utilize only one circulation fan. Unique circuitry allows virtually any power source to be used.
