Basics of Corn Stoves
Corn stoves are specifically designed to burn a granular fuel. Because this fuel is metered into the burning chamber, most stoves have a storage hopper to contain a supply of fuel. In some ways, corn burning stoves are very similar to pellet burning stoves. In both cases, corn and pellets are very dense. Consequently, neither of these fuels will burn readily in an open pile in a fire chamber.
To get these fuels to burn, some manufacturers use a small combustion chamber into which the corn is fed and combustion air is pumped through. The corn can be either dribbled into the combustion chamber from above, or it can be stoked into the chamber from below by means of an auger. The feed rate of this auger can be adjusted to regulate the amount of corn burned, which in turn controls the amount of heat produced. The second requirement for burning to occur is oxygen. In order to support combustion, oxygen is blown into the combustion chamber by means of a small fan.
Inside the stove, a heat exchanger is used to remove heat from the flue gasses and heat the room air. A fan is used to move the room air through the stove where it is warmed. This fan may also help in moving the heat further away from the stove.
The type of flue pipe required to vent the exhaust gases from the stove will depend on the design of the stove or corn burning appliance. Follow the manufacturerâ€™s recommendations regarding the type of flue pipe required. It is best to keep the flue pipe as short and straight as possible (keep the number of elbows to a minimum) to maximize the stoveâ€™s performance.
The corn fired central furnace and residential boiler are approved by Underwriters Laboratories. Using a dual auger drive system to meter the fuel allows for the precise and safe control of combustion. The UL listing assures you of a safe and quality product. The boiler is ASME certified.
