Portable Stove

A portable stove comprising:

• a rectangular outer body having walls coupled together with offset hinges that permit the stove to fold leaving a cavity between the walls and an opening in at least one wall for loading fuel into the stove;
• a rectangular combustion chamber located inside the outer body such that there is space between the outer body and the combustion chamber, the combustion chamber having walls coupled together with hinges that allow the combustion chamber to fold, an opening in at least one wall for loading fuel into the inner body, a floor configured to rest inside the combustion chamber, a plurality of secondary air openings along an upper portion of at least one wall of the combustion chamber, and a plurality of upright posts located along the walls of the combustion chamber;
• an air dam configured to rest upon the upper edge of the walls of the combustion chamber to direct air flow from the space between the outer body and the combustion chamber through the secondary air openings in the wall of the combustion chamber, the air dam further having an opening to permit flame and exhaust gases to exit the combustion chamber;
• and
• whereas the combustion chamber and air dam fit within the outer body when the stove is folded.

A method of heating a portable stove comprising:

• unfolding an outer body until it forms a rectangular shape, the outer body having walls coupled together with hinges and an opening in at least one wall for loading fuel into the stove;
• locating a rectangular combustion chamber inside the outer body such that there is space between the outer body and the combustion chamber, the combustion chamber having walls coupled together with hinges that permit the stove to fold, an opening in one wall for loading fuel into the combustion chamber that aligns with the opening in the outer body, a floor, a plurality of secondary air openings along an upper portion of at least one wall of the combustion chamber, and a plurality of upright posts located along the walls of the combustion chamber;
• placing an air dam configured to rest upon the upper edge of the walls of the combustion chamber to direct air flow from the space between the outer body and the combustion chamber through the secondary air openings in the wall of the combustion chamber, the air dam further having an opening to permit flame and exhaust gases to exit the combustion chamber;
• and
• loading fuel into the combustion chamber and lighting the fuel with a source such that the heat from the lit fuel draws air through the stove to continue to burn fuel.
