A high efficiency bio-fuel pellet and corn burning furnace. The furnace has a series of augers to load the fuel into the burn pot, move the fuel through the burn pot and finally remove the ash from the system. The burn pot or combustion area as two parallel augers with counter rotating flights so as to move the combustible material towards the area between the burn pot augers and from one side of the burn pot to the other during combustion so as to prevent clumping and aid in complete combustion.
