A Corncob-Fueled Drying System

ABSTRACT A system to collect, transport, process, dry and burn corncobs to dry shelled corn was evaluated. A mixture of shelled corn and cobs was harvested and transported to the drying facility where a continuous, automated system separated, dried and conveyed cobs to the combustor, a two-stage downdraft device with a 400 to 800 kW heat output. Exhaust products were put directly into the drying air without adversely affecting the corn's appearance or odor
