A corn furnace comprises a hopper for storing corn to be burned, and a combustion chamber in which corn is burned in a pot of fire to produce heat. An endless screw, supplying corn from the dispensing bottom of the hopper to the combustion chamber, comprises a lower proximate end for receiving corn from the hopper, a higher distal end for discharging corn in the combustion chamber through an inclined conduit, an elongate tubular member extending from the proximate to the distal end, and a generally helicoid blade rotatively mounted in the tubular member for conveying corn through that tubular member. The rotative helicoid blade is formed with a sharpened distal outer helical edge section. An air blower system supplies air to the distal end of endless screw to produce in the tubular member a flow of air in a direction opposite to the movement of the corn to remove from this corn dust and other impurities. To better sustain combustion of corn in the perforated pot of fire of the combustion chamber, air is supplied in the pot of fire through the inclined conduit, air is supplied in the pot of fire through the perforations thereof, and air is deflected from underneath the pot of fire toward an area of the combustion chamber above that pot.
