A method of infusing wood grilling products with flavor and aroma-enhancing supplements is utilized to impart flavor and aroma to a wood grilling product that is to be used for cooking. The wood grilling product is placed into a vacuum infusion chamber and submerged within a first quantity of FAE liquid. The first quantity of FAE liquid and the wood grilling product are then hermetically sealed within the vacuum infusion chamber. A first quantity of air is evacuated out of the vacuum infusion chamber in order to apply a vacuum to the wood grilling product. The vacuum is maintained on the wood grilling product for an optimal time duration. A second quantity of air is then introduced into the vacuum infusion chamber in order to return the vacuum infusion chamber to atmospheric pressure and infuse the first quantity of FAE liquid into the wood grilling product.

Gas hydrate slurry formation systems are provided. The gas hydrate slurry formation system includes a cavitation chamber configured to receive a fluid and a cavitation device placed within the cavitation chamber. The cavitation device is configured to form a plurality of bubbles within the fluid in the cavitation chamber. The gas hydrate slurry formation system also includes a gas inlet configured to introduce a gas within the cavitation chamber such that the gas is entrained in the plurality of bubbles to form a plurality of gas-entrained bubbles. The plurality of gas-entrained bubbles implode within the cavitation chamber to form a gas hydrate slurry.

This invention relates to solid firelighters of the type which may be used to initiate combustion of i) barbecues (BBQs), irrespective of whether the barbecue fuel is in the form of charcoal lump wood or briquettes, ii) natural wood in outdoor wood fires or iii) any domestic or commercial fires. Firelighters of the present invention comprise: 25 to 75% by weight fibreboard having a density of from 0.1 to 0.5 g/cm.sup.3; and 25 to 75% by weight palm fatty acid distillate; wherein the fibreboard is impregnated with the palm fatty acid distillate.

A production apparatus of an ashless coal includes a preheater, an extraction tank, a feed pipe, a solid-liquid separator and a solvent separator. The preheater heats a solvent. The extraction tank extracts a coal component soluble in the solvent from a slurry including a mixture of a coal and the solvent heated by the preheater. The coal feeding unit feeds the coal to the feed pipe by pressuring a feed part to the feed pipe such that the solvent does not flow back. The solid-liquid separator separates a solution part containing the coal component from the slurry. The solvent separator evaporates and separates the solvent from the solution part to obtain an ashless coal.

A fire starter device and method for producing the same capable of igniting a fire sustaining fuel source in adverse conditions typically associated with wilderness survival or emergency situations. A wick element facilitates ignition of the fire starter and extends through a generally cubical outer shell into a solid fuel inner core. The wick element can include one or more wicks associated with a wax, each wick including multiple strands of one or more wicking materials. The outer shell provides a hard, non-greasy external surface for the fire starter and substantially encapsulates the solid fuel inner core. The solid fuel inner core includes a fibrous material associated with a wax and can provide fuel to the flame of the fire starter.

A pipeline transportation method of coal is provided. The coal is pulverized and then subjected to a waterproofing treatment, so that a time needed for precipitating the pulverized coal in water is longer than a time needed for transporting the pulverized coal by flowing water to a destination. The waterproof pulverized coal is transported by water through a pipeline. After reaching the destination, the waterproof pulverized coal can be separated from the water in a static pool, collected by a cyclone separator, and then stored in a warehouse.

A method of capturing and disposing of fats, oil and/or grease is disclosed. The method comprises: providing a porous container formed of a porous fabric; positioning in the porous container an absorbent material capable of absorbing a quantity of fats, oil and grease through the porous fabric of the porous container; placing the container and the absorbent material contained therein in a grease trap comprising a source of fats, oil and/or grease for absorbing the fats, oil and/or grease; removing the porous container of absorbent material and absorbed fat, oil and/or grease from the source of fats, oil and/or grease; removing the absorbent material, fats, oil and/or grease from the removed porous container; and extracting the absorbed fats, oil, and/or grease from the absorbent material.

A method of capturing and disposing of fats, oil and/or grease (FOG) is disclosed. The method includes providing a vacuum truck to a user, wherein the vacuum truck has a tank with (1) a vacuum hose; (2) an inlet to the tank connected directly to the hose; (3) an outlet from the tank; (4) and one or more mixing components. The method also calls for positioning an absorbent material within the tank that is capable of absorbing a quantity of FOG. Next, FOG is vacuumed from a grease trap via the hose and mixed with the absorbent material to create a biofuel. Finally, the biofuel is discharged from the outlet of the tank into a containment device at a burn facility and subsequently burned. Alternatively, the absorbent material may be contained within a containment device at the burn facility and mixed with the FOG at the facility before being burned.

A method for storing a modified coal includes a pile forming step of forming a pile by stacking a blended coal of an agglomerate-shaped coal and a powdery modified coal. The modified coal has a content of particles having a particle diameter of 2 mm or less of 35% by mass or more. The pile formed in the pile forming step has a packing density of 1.0 g/cm.sup.3 or more.
