Corn stoves are again gaining interest as a means to heat homes. More than 20 companies make a range of sizes and models of corn-fueled appliances such as stoves and furnaces, which can be tailored to specific needs. The decisions to consider corn as a fuel are which stove, furnace or boiler to buy and how to store the fuel corn.
Corn used as a fuel in stoves can be of a lower quality than Grade No. 2. Where possible, use non-food grade corn.
There are some quality requirements for this corn fuel: Shelled corn must be dry, preferably 15% moisture content or less. Corn higher in moisture will have a lower heat value per unit. Shelled corn must be free of fines. Dirty corn, which has a lot of fines and cob pieces, will cause problems with the fuel delivery system. Dirty corn may also cause bridging in fuel hoppers.
