The boiler's top output is 100,000 Btus. The company also expects to have a corn-fired corn dryer available in the next couple of years. Both companies agree that burning corn is cleaner than firewood. There are no moths, beetles, ants or bark that come in with corn, and corn is 2 percent ash while wood is around 15 percent. We add a little bit of oyster shell so clinkers don't form.
Clinkers are hard masses of fused matter resulting from the burning of corn.
SnowFlame, a North Carolina company, manufactures a line of stoves that are more directly competitive with the AES stove. SnowFlame's three corn-burning stove models, all of which are UL rated, have Btu outputs ranging from 10,000 to 40,000. SnowFlame also makes a line of corn-burning cooking grills. Envirotec also makes a line of UL rated corn-burning stoves ranging from 32,000 to 60,000 Btus. They build up no creosote in the pipes like wood does.
