how do pellet stoves work?
Pellet stoves are a complex machinery that utilizes electrically controlled combustion systems, blowers, and heat exchangers. In real talk that means that the stoves are designed to burn slowly, release as much energy as possible from the fuel source, and pull the cool air into the stove and blow it back out as hot air. The pellets are poured into a holding area called a hopper. If the hopper is very large it can hold enough pellets to burn for a couple of days. The average pellet stove is designed to heat for one to two days on a load of pellets. Inside the stove is an auger. The job of the auger is to control the rate at which the pellets are delivered to the fire. If the rate is set at, say, one pound per hour, a slow fire is produced, warming the room for a long time. If the rate is four or five pounds of pellets an hour the fire will be roaring and very hot. The rate of delivery on some stoves is controlled by a thermostat, while on other stoves it is a manual setting.
Pellet appliances automate as many functions as possible. The most significant is fuel delivery. The heat setting made by the operator controls an auger or similar feed device that delivers regulated amounts of fuel from the hopper to the fire (Figure 2). Automatic fuel delivery from the hopper frees the operator from frequent attention and loading, while providing clean burns and the desired comfort level. The amount of air needed for optimum combustion efficiency is delivered automatically or with minor manual adjustments. In most designs, a fan delivers air to the fire and blows exhaust by-products out of a vent pipe that is smaller and typically less expensive than a chimney (Figure 3). In most designs, a fan delivers heat to the home by blowing air through heat exchangers in the stove and out into the home. Heating efficiency is greatly enhanced by removing the heat from the appliance before it can exit the system.

A. Pellet stoves burn pellets much like a forge burns coal. The stove automatically turns an auger which feeds pellets into the burn pot. The exhaust blower pulls air into the burn chamber with great speed, causing the pellets to burn very efficiently, then pushes the exhaust out of the exhaust pipe. A heat exchange blower moves room air through tubes traveling inside the burn chamber then out into your room. No smoke enters the room. When you require more heat, turning up the stove will increase the amount of pellets fed into the chamber.
