A COST ANALYSIS

All heat output is measured in terms of BTU’s. One BTU is the amount of heat needed to raise one pound of water one degree.

Available heat per unit in alternative sources of fuel:

Note: Shelled corn can be purchased at reduced prices (i.e. moldy corn, scorched corn, etc.).

The BTU content of shelled corn will vary between

8,000 to 10,000 BTU’s per pound.

Use corn at 14—15% moisture content for peak efficiency.
