Abstract: An improved burner apparatus for a furnace that uses corn or other pelletized material for fuel. The apparatus includes a self cleaning rotating floor made of a generally cylindrical slowly rotating drum having a first paddle section and a second paddle section separated by an intermediate section. A plurality of paddles in each of the sections slowly rotate to control the flow of material and waste. Using this rotating floor and arrangement to aid airflow in the process of burning corn or pelletized fuel allows for effective combustion.
