Abstract: A portable stove for burning charcoal and other solid fuel has a continuous vertically oriented insulative side wall. This wall has a continuous bottom edge and its surrounds and defines a hollow fuel chamber. The fuel chamber has an open top. A grate is positioned adjacent the insulative wall proximal to the bottom edge of the insulative wall. As so positioned the grate forms the bottom of the fuel chamber. The insulative wall has a plurality of apertures located along its bottom edge with the apertures spaced around the insulative wall in an array immediately adjacent the grate. A reflector plate is positioned below the grate. An air chamber for channeling combustion air surrounds the reflector plate, the underside of the grate and the bottom most portion of the insulative side wall including the apertures therein. An air control damper is located in the air chamber for controlling the introduction of air into the air chamber.

Abstract: A biomass stove has an outer chamber formed by a continuous side wall which is connected to a bottom wall. An air inlet is formed in the bottom wall for allowing introduction of air into the interior of the outer chamber. A fuel basket, also formed as a continuous side wall attached to a bottom wall, is located within the outer chamber. In the fuel basket, near the bottom of the fuel basket, a grate is positioned. First and second reflecting members are positioned below the grate within the fuel basket. Air inlets are located along the bottom periphery of the fuel basket with primary air flowing up through the air inlets and over the reflecting members and through the grate into a fuel supply which can be located within the fuel basket on the grate. One or more of the primary stoves can be suspended in a support housing to form an appropriate multi-burner stove.

Abstract: A small compact stove capable of burning a variety of carbonaceous fuels has a base and located on the base is a vertically oriented cylindrical wall. The wall is formed of a heat conducting material and has open bottom and top ends. The interior surface of a portion of the wall forms a combustion chamber. A grate is located within the wall at the bottom end of the combustion chamber. The primary air chamber is located at the open bottom end of the wall and primary air is conducted through it and then up through the grate into the combustion chamber. A secondary air chamber surrounds at least a portion of the wall such that the wall forms one of the surfaces of the secondary air chamber. The wall includes a plurality of air passageways between the secondary air chamber and the combustion chamber such that air can flow within the secondary air chamber in contact with the exterior surface of the wall and be heated by heat conducted through the wall from the combustion chamber.

Abstract: A portable forced draft solid fuel burning cooker in which a duct defining base supports a centrally disposed electrically operated blower unit. Two heater units that use fuel such as briquets, acorn, small pieces of wood, twigs and the like are supported from the base on opposite sides of the blower unit. First and second manually operated dampers are provided in the base to selectively permit a desired volume of air from the blower to flow to either the first or second heater unit, or concurrently to both units. Individual cooking utensils may be heated to different temperatures on the first and second heater units if desired, by controlling the volume of air flowing to each of the heater units. A heat conducting grill may be extended across both heater units, and utilized to cook pancakes and the like.
