Illustrative Examples of Using the Corn vs. Wood Pellets EnergySelector
Consider the case of shelled corn having the value of $2.50 per
50 pounds and the price of wood pellets is $250 per ton. In this
case, the intersection point of these two values on the EnergySelector
is in the "Burn Shelled Corn" territory. Just on the
basis of heats of combustion, it is cheaper to burn corn than
wood pellets for this example.
Consider the case when the value of the shelled corn is $5.00
per 50 pounds and the price of wood pellets is $150 per ton. Now
the intersection of these two values is in the "Burn Wood
Pellets" territory.

Additional Expenses
There are additional expenses associated with burning corn in
place of wood pellets. Additional expenses include burner purchase
or modifications, proper handling and storage facilities for the
corn, emission controls of combustion gases, and disposal of ash
residue. These expenses are certainly not trivial and must be
considered before any plans are finalized to burn shelled corn
instead of wood pellets. Check with the manufacturer of any burner,
stove, boiler, or furnace before making any modifications.
