Pellet Stove Auger Motor Requirements For Wood Pellet Fuel Flexibility

There are many core components in a pellet stove, including the burn pot, heat exchanger and the feed auger and auger motor. When consumers are choosing a pellet stove, the auger and auger motor are a very over looked components. However the power of the auger motor and drive system impact directly on how well the pellet stove can deal with different types and batches of pellet fuel. The main issue that related to pellet stove auger motor requirements is the length and density of pellet fuel. Pellet fuel is produced at various different lengths depending on the knife setting in the manufactures pellet mill. Therefore some pellets are longer than others. Depending on the design of the pellet feed system and power of the auger motor, a pellet maybe required to be broken to fit through the auger feed tube. However in some pellet stoves this can cause serious issues, and potentially damage the auger, auger drive or auger motor.

These issues also relate to the design of the pellet hopper and pellet feed chamber. Many pellet stoves operate with a drop down burn pot design, which is very limited in the type of pellet fuel it can deal with. With a drop down burn pot design, the pellets are taken from the hopper and are carried to the burn pot in a vertical incline, before dropping down into the burn pot. A vertical incline in the auger feed system is especially prone to blockages from oversized pellets. This design of hopper and pellet feed system is also prone to blockages due to pellet fines. Pellet fines are dust particle from the pellets, these collect in the base of the pellet hopper. As the amount of pellet fines increase, the fines cannot be taken up the vertical pellet feed, and therefore stop pellets going up the feed incline to the pellet stove burn pot. Once the pellets actually reach the burn pot, there are also pellet fuel limitations. Drop down burn pots only remove ash through the movement of air generated by the combustion fan, this relies on the pellet fuel creating very little ash. If the wood pellets generate more ash than say premium wood pellets, the burn pot will block and the pellet stove will fail.

Looking For More Adaptable And Tolerable Wood Pellet Fuel Stoves

Purchasing a pellet stove is a not a decision you will make very often, therefore the decision on which stove you do purchase is even more important. You obviously want to buy a pellet stove which will provide the best long term investment, and operate with as little issue as possible. Well to do this you will avoid such features as a vertical auger pellet feed and also a drop down burn pot. Other designs of burn pot are far more capable of burning a wider range of pellet fuels without complications. However many manufactures still majority produce drop down burn pot designs as they are cheaper to produce. Therefore you need the knowledge of what questions to ask your pellet stove dealer.
