Variable fuel cooker

A device for delivering and burning variable combustible material, comprising:

• a hopper for holding the combustible material;
• a burn box to receive and burn the combustible material;
• a programmable auger, pivotably connected within an auger tube to facilitate adjustment of an auger's orientation within the auger tube in response to irregularly sized or shaped combustible material, through which the combustible material is moved from the hopper to the burn box;
• a programmable agitator coupled to the hopper and configured to engage the combustible material as it leaves the auger;
• and
• a microprocessor configured to receive selection of a fuel type of combustible material, wherein after receipt of the fuel type selection the microprocessor is further configured to adjust one or more of the airflow into the burn box or the feed rate of the combustible material to facilitate burning of the combustible material.

A method for controlling a device configured to use at least two different combustible material fuel types, the method comprising:

• receiving selection of a fuel type of combustible material;
• loading a hopper with a combustible material;
• transporting the combustible material from the hopper to a burn box via an auger running between the hopper and the burn box;
• adjusting the auger's orientation within an auger tube in response to irregularly sized or shaped combustible material to facilitate transportation of the combustible material from a hopper to a burn box;
• and
• adjusting one or more of the airflow into the burn box or the feed rate of the combustible material to facilitate burning of the combustible material, wherein the feed rate is between 1.5 and 2.25 times higher speed for wood chips than wood pellets.
