A heating device having a burn chamber that includes at least one opening, a conduction chamber adjacent to the burn chamber and including at least one aperture, a heat manifold including a first port and a second port, and at least one source vent extending between and coupling the first port of the heat manifold to the at least one opening of the burn chamber, and at least one exhaust vent, protruding from a surface of the heat manifold and extending between and coupling the second port of the heat manifold to the at least one aperture of the conduction chamber.

A self-contained portable cooking system that prevents mess and facilitates storage and transportation. In one embodiment, a portable cooking system includes an outer container defining a chamber; and a cooking unit being configured to be entirely contained within the chamber of the outer container, the cooking unit being removable from the outer container. In one embodiment, a method of using a portable cooking system includes removing the cooking unit from the outer container, placing an open second end of a cooking column of the cooking unit on a support surface, and placing a cooking platform of the cooking unit on an open first end of the cooking column.

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 fuel—typically 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 cooking stove (2) comprising a fan (14) configured to force air into a combustion chamber (8) through air inlets (10) in the walls (4) of the combustion chamber (8). The air inlets (10) are positioned at least 30 mm from the base (6) of the combustion chamber (8) and direct the forced air to the headspace above the fuel (20). Clean combustion of high energy fuels can be achieved by the cooking stove (2).

The present invention generally provides an improvement upon existing wood-gas stoves, in which the invention makes it possible for a user to start the fire in a well-ventilated single-walled stove configuration, and then easily and instantly convert the stove into a double-walled wood-gas stove configuration for improved start-up and boil times as well as increased fuel efficiency of the stove and reduced smoke particulates emanating therefrom. The invention also improves air flow and pyrolysis efficiency by elevating the canisters above the surface below, allowing less restricted air flow from underneath and a greater distance and time for gas to heat up between the canister walls.

The present utility model discloses an oil-smoke removal device, including an oil-smoke removal device body, which is provided with an air inlet at one end, and an air outlet at the other end, and an absorption and decomposition device for decomposing and absorbing the oil-smoke is provided in the middle of the oil-smoke removal device body. The oil-smoke removal device provided by the present utility model is a structure mainly applied for absorbing oil-smoke during barbecue, and it uses the absorption and decomposition device in the structure to achieve the objective of effective adsorption and decomposition of the oil-smoke contained in the oil-smoke gas, which greatly reduces the environmental pollution caused by oil-smoke emissions, resulting in a very good effect in the practical application.

The invention is a novel Top-Lit-Updraft cook stove with internal forced primary and secondary air, designed to burn biomass. The cook stove is specifically designed to cleanly burn biomass. The stoves design innovations include a cylinder-within-cylinder design to provide heated, forced secondary to the burner area right below the burner. The burner design addresses limitations in previous cookstove burner design by implementing a bluff body design to direct syngas to the secondary air jets, improving mixing and combustion of volatile gases.

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.

There is described a portable oven, such as a wood-fired oven. The oven comprises a housing and a cooking surface arranged within the housing. The housing comprises a skirt extending below the cooking surface such as to raise the cooking surface from the bottom edge of the oven. There is also provided a method for making a portable oven.
