A flammable tube has a plurality of air passages formed along the length of the flammable tube. A support member is positioned in an interior of the flammable tube. The support member is spaced apart from the lower end of the flammable tube. Solid fuel is positioned on the support member. A flame is introduced to the solid fuel which is within the interior of the tube which ignites the solid fuel, such as charcoal. The charcoal burns away the flammable tube and the support member. The flammable tube may be placed within a grill of the type used to cook food or other container that is nonflammable, and which provides a receptacle for the burning solid fuel without the need of a specialized grilling apparatus.

Grills configured with adjustable and moveable radiant barriers may include a body, a lid, a cooking grate, a combustion space within the body and two plates making up part of the adjustable and moveable radiant barriers. The first plate may include openings through which radiant heat may pass and the second plate may have similar openings. The lid and the body may form a cooking enclosure with the interior cooking grate being substantially parallel to both the first plate and the second plate. The two plates may be configured to move relative to one another such that the openings may alternatingly align and offset creating an adjustable rate of transmission of thermal radiation between the combustion space and the cooking grate. The plates of the radiant barriers may further be configured to move together relative to the body of the grill thereby varying the rate of transmission of thermal radiation between the combustion space and the cooking grate.

One or more implementations of the present disclosure relate to a reusable or disposable outdoor wood or charcoal-fired cooking device. In at least some implementations, embodiments of the present disclosure include one or more of a cooking vessel, a fuel cartridge of combustible fuel (e.g., wood, charcoal) that is positionable within the cooking device, and a control device that includes or controls the operation of a fan, which in turn precisely controls the combustion of the fuel and the conditions within the cooking vessel. The fan may be operative to push or pull air through the fuel cartridge. When the fan is turned off or at low speed, the combustion gases from the fuel cartridge may be vented directly to the ambient environment without passing through the cooking vessel. The cooking vessel and fuel cartridge may be made from materials that are disposable, and ideally recyclable and/or compostable.

The invention is directed to a disposable or reusable barbecue (202) comprising a tray (204) forming a cavity for containing a fuel unit (205) like charcoal, a cooking grate (208) and a stand (206) for operatively holding the tray (204) and the cooking grate (208; 308) relative to each other; wherein the tray (204) is rectangular and comprises two parallel lateral shoulder edges (216); and the stand (206) comprises lower support surfaces (206.3) for said lateral shoulder edges (216), the support surfaces being configured for allowing the tray to be slid along said surfaces, and upper support surfaces (206.6) for the cooking grate (208)

A portable grilling system comprising a grate formed of a non-flammable material; at least two support members formed of a non-flammable material and pivotally attached to the grate; at least one fuel insert support member formed of a non-flammable material and positioned below the grate; and a fuel insert comprising a base tray formed of a biodegradable material having a bottom surface and one or more sidewalls extending upwards from the bottom surface; a biodegradable and non-flammable liner positionable within the base tray; and a fuel source positionable within the liner.

Grills configured with adjustable and moveable radiant barriers may include a body, a lid, a cooking grate, a combustion space within the body and two plates making up part of the adjustable and moveable radiant barriers. The first plate may include openings through which radiant heat may pass and the second plate may have similar openings. The lid and the body may form a cooking enclosure with the interior cooking grate being substantially parallel to both the first plate and the second plate. The two plates may be configured to move relative to one another such that the openings may alternatingly align and offset creating an adjustable rate of transmission of thermal radiation between the combustion space and the cooking grate.

A multifunctional and portable cooking implement includes a deep fryer module, a cooktop module and an oven-grill-griddle module, which may be configured between the deep fryer module and the cooktop module. The multifunctional and portable cooking implement provides a plurality of means to cook and warm food items in a compact form and may have legs that pivot about respective leg hinges to elevate the modules, above a ground surface. The exemplary multifunctional and portable cooking implement may have a length from a first end to a second end that is configured to fit within a truck bed and on a tailgate of a truck. A cover-countertop may be pivotably coupled to one or each end of the portable cooking implement to pivot open to provide countertop space for food preparation.

A disposable grill including a base tray as an outer grill cover made in a flammable material, a fuel shaped in a combustible biomass material, and an insert structure made in a heat insulating material for holding the fuel and being partly or fully covered by the base tray, wherein at least one wall thickness of at least one location in the insert structure being defined by one or more characteristics of the fuel and the base tray.
