A study was conducted to determine the feasibility of using Iowa coal as a fuel source for on-farm corn drying. Two furnaces tested operate at 50 to 55% efficiency. Two existing on-farm systems were described. A cost analysis showed energy costs for coal were less than for propane, but heating system costs are about equal and do not favor a shift to coal.
