Abstract: 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.

Abstract: A composite heat source for use in a smoking article is provided, including a non-combustible porous ceramic matrix; and a particulate combustible fuel embedded within the non-combustible porous ceramic matrix. The non-combustible porous ceramic matrix is formed from one or more particulate materials having a median D50 particle size at least five times less than the median D50 particle size of the particulate combustible fuel. Preferably, the non-combustible porous ceramic matrix includes one or more transition metal oxides.

Abstract: A method and apparatus is disclosed for a rechargeable fire starter and a long burning fuel. The disclosure relates to a rechargeable fire starter and long burning fuel. The rechargeable fire starter and long burning fuel may comprise an absorbent having a porous mineral, or a combination of one or more porous minerals along with wood pellets. The absorbent may then be saturated with a flammable liquid. This combination provides a rechargeable fire starter and long burning fuel that is relatively impervious to moisture.

Abstract: A sustained release composite is made from a three-dimensional piece of calcium silicate having a xontolite structure and in which are fibers of textile glass and borosilicate glass, and an active agent. The active agent can be a fire starting material, a fragrance, or a masking fragrance.

Abstract: A firelog and grate system wherein the firelog is supported by the grate in a generally upright orientation includes a bed and at least a first support member. The firelog contains at least a first support surface. The first support surface of the firelog rests against the first support member of the grate, thereby retaining the firelog from movement in the downward direction, the frontward and rearward directions, and the left and right directions. The grate may contain multiple support members to support multiple firelogs for simultaneous burning. The support members can constitute plates, pins, or support lugs. In the plate configuration, the support member inhibits the burning of the firelog in the rearward direction, i.e., the direction which cannot be observed, thereby producing less unnecessary heat.

Abstract: A fuel ignition arrester system that has a feedback control to maintain the fuel/air mixture in the ullage of a fuel tank above the flammability range. The system uses a photoelectric detector to signal when the fuel/air mixture concentration falls or rises to a predetermined concentration value. The predetermined value is selected to be higher than the upper limit of the flammability range so that the fuel/air mixture is maintained above the range and, thus, incombustible. A fuel pump and piping system with nozzles is arranged to inject fuel into the ullage when the concentration falls to the predetermined value and to stop injecting fuel when the concentration rises to the predetermined value. A flammability detection system includes the detector and a controller that produces an annunciating signal when the fuel/air mixture concentration is equal to or between the upper and lower limits of the flammability range.

Abstract: A fuel composition comprising a non-combustible, substantially heat resistant pervious substrate and an amount of propylene glycol disposed on the substrate sufficient to fill the majority of the surface interstices present in the substrate and an apparatus for providing a heat source suitable for cooking comprising a container having a liquid impervious bottom wall and a peripheral side wall extending generally upward from the bottom wall to define a container mouth, a non-combustible, substantially heat resistant pervious substrate disposed in the container and propylene glycol disposed on the substrate.

Abstract: Prepackaged fuel holder and fine pan for picnic cooking comprises a body portion having at least one recess therein for receiving a fuel, as for example, charcoal briquettes. A plurality of spaced wires extend across the recess to facilitate moving the fuel holder and fire pan when it becomes too hot from use to be handled. Also, a removable, flat cover is disposed over the recess to retain the fuel in the recess and permit stacking of a plurality of fuel holder and fire pans for marketing purposes. In another embodiment the fuel holder and fire pan has a perforated floor to form a false bottom and a chamber in the recess. The chamber functions to receive ash and provide combustion air upwardly around the fuel.

Abstract: A permanent briquette for imparting flavor to food being cooked on gas and electric grills consisting of a permanent briquette saturated with a liquid smoke composition.
