An oven for cooking foods includes a housing having a fire chamber and a cooking chamber disposed generally above the fire chamber. A vessel is receivable in the fire chamber and is adapted to hold combustible material therein to generate heat and smoke for cooking food in the cooking chamber. A blower is mounted on the housing. The blower is selectively operable to move air. A tube is attached to an outlet of the blower and extends into the fire chamber such that when the vessel is received in the fire chamber the tube extends to a position adjacent the vessel so that air from the blower is blown directly into the vessel without first passing a heating element. The oven does not require supplemental heat from a burner or similar heating element.

A heating or cooking method and apparatus is provided. The heating or cooking method or apparatus includes an insulated combustion chamber having an opening at one end and an extension ring extending from the open end. The extension ring may have at least one tab extending from the extension ring, configured to provide an air exhaust space when a piece of cookware is used with the heating apparatus. A fuel receptacle configured to fit inside the combustion chamber has a raised center section with at least one heat channel and a peripheral section with at least one hooded slot. The fuel receptacle may also have a lateral wall separated from the inner enclosure wall of the combustion chamber by a space when the fuel receptacle is situated within the combustion chamber. A grill having essentially the same perimeter shape as the fuel receptacle and a handle is also provided.

A gasification stove includes an upper housing including an upper hollow body and a dome section, and a lower housing including a lower hollow body that form a stove chamber when connected to each other. A separator for collecting a gas and flame generated from burning of the biomass is arranged in the stove chamber and includes a bowl section and a chimney section. The bowl section has a first set of holes, and an upper part of the chimney section has a second set of holes. The upper part of the chimney section is air-tightly attached to an edge of a chimney opening of the upper housing. At least some of the gas flows through the first set of holes and the second set of holes to enter into the chimney section so as to react with the flame or hot air in the chimney section to generate additional flame power.

An apparatus including a frame component into engagement with a front panel segment, a side panel segment, a rear panel segment, and a roof panel segment to form an enclosure. A rear opening is formed with an overhand portion and an exhaust member, wherein a vertical offset of the rear opening with respect to a front opening is configured to create a draw from a proximate front section to a proximate rear section of said frame component, wherein said draw is operable for pulling smoke or flame towards the rear opening.

This invention provides a portable combustion device that provides a cleaner combustion, provides a more efficient overall combustion through the use of a fan that directs a predetermined volume of airflow over the combustible fueltypically wood or similar cellulose-based biological solids and provides a cooking surface that is a grill top. The combustion device has a combustion chamber into which the fuel source is placed for combustion. Mounted to the side of the combustion chamber is a housing that encloses the TEG, which generates an electrical output, based on a difference in temperature on opposing sides. Mounted onto the TEG housing and protruding into the combustion chamber through a small passageway is a heat-conducting probe and heat-conducting probe base unit.

A portable camping and survival stove includes a stand comprising a pair of flat stock lower cross-members adjoined via a complementary slot in each member, each lower cross-member having a lower edge and a pair of double tabs spaced apart on an upper edge configured to secure on a shelf there between a lower edge of a rigid container. The disclosed stove also includes a cook top comprising a pair of flat stock upper cross-members adjoined via a complementary slot in each member, each upper cross-member having an upper cooking edge and a pair of double tabs spaced apart on a lower edge configured to secure on a shelf there between an upper edge of the rigid container. Furthermore, the rigid container may be a discarded can or a collapsible four-sided container for flammable material and include holes for air flow in a bottom and at least one side thereof.

A combustion furnace includes an inner shell, an outer shell, a gas inlet piping and a flame inhibiting cover. The inner shell defines a receiving cavity therein. The inner shell defines a plurality of first gas holes around the periphery of a top portion thereof. The inner shell defines a gas inlet hole at a bottom thereof. The outer shell encloses the inner shell such that a gas flowing space is defined between the inner shell and the outer shell. The gas inlet piping has an opening formed at one end thereof, and the gas inlet piping communicates with the gas flowing space. The flame inhibiting cover is atop the outer shell and the inner shell, and a lower flange of the flame inhibiting cover is below the first gas holes.

A method for making wood-fired pizzas at a customer designated location for an event comprises assembling a portable wood stove at the location, setting up a customized pizza assembly station adjacent the assembled stove and then individually making TO ORDER pizza pies for rapidly baking in that wood fired stove. After everyone's had their fill, the stove can be cooled, disassembled and carted off to its next event location for customized wood-fired pizza making for that event's attendees.

A wood stove that includes a hollow cylindrical outer skin with an coaxially aligned, insulated inner fire box. Located below the fire box is a fresh air inlet and an air control valve that controls the flow of fresh air into the stove's primary and secondary chambers. Surrounding the fire box are three longitudinally aligned air conduits that extend from the air inlet to an upper ledge located below a secondary combustion chamber. During use, the fresh air inside the air conduits is heated. Disposed transversely inside the outer jacket and above the primary chamber is a combustor assembly that includes a lower fin plate, a perforated intermediate plate and a perforated upper plate. During use, fuel is added to the fire box which undergoes initial combustion and produces hot gases and fumes that travel upward towards the chamber assembly. The air control valve controls flow of fresh air into the primary chamber only, both chambers, or into only the secondary chamber.
