Abstract: A portable charcoal barbeque grill is disclosed with self-contained charcoal briquettes and an upper grill for cooking. The barbeque grill may be constructed with a starter wick having relatively low ignition-temperature for easy lighting. The wick also has a sufficiently high burning temperature either to ignite charcoal briquettes or to ignite a starter material which in turn has a starter-material-burning-temperature sufficiently high to ignite the charcoal briquettes.

Abstract: In this invention, there is provided a method for reducing NOx emission from an internal combustion engine designed to produce a given amount of power and a method for improving fuel efficiency by providing an intake stream of oxygen-enriched air and keeping the amount of power output the same so that the combustion temperature in the engine is lower.

Abstract: A gasification process for making producer gas is disclosed. A consistent quality of raw carbon source material is supplied for gasification. The impurity content of the raw carbon source material is adjusted to within an acceptable consistent range of impurity content. The raw carbon source material is heated in a non-oxidizing environment to adjust the tar content and to remove volatile hydrocarbon constituents and to produce a devolatilized carbon source material. The devolatilized carbon source material is gasified by heating the carbon source material to a gasification temperature in a gasification generator, supplying steam, and supplying enhanced oxygen content air to react with the devolatilized carbon source material and to thereby form consistent, high energy value, low impurity producer gas.

Abstract: A carbonaceous material, also referred to as a carbon alloy, and a process of making the carbonaceous material is provided. A particulate of partially pyrolyzed carbon (PPC) base is formed on heating a carbon-containing feed material and a nucleating agent in the form of a interactive filler is included. The nucleating agent is adhered together to the PPC particles by application of heat.

Abstract: A tunnel oven and method for heating transported carbonaceous material includes an enclosure with a passage having a first and second length and an interconnection between the first and second length. A transport device in the passage moves solid carbonaceous material through and along the first length of the passage. A water cooling mechanism along the second length of the passage and a cooling controller operatively coupled to the cooling mechanism to provide a quantity of water for cooling the carbonaceous material to a temperature below the oxidation temperature of the carbonaceous material in air and above the boiling point of the water so that the quantity of water is completely vaporized to form steam and the carbonaceous material is discharged at the cooled temperature without any liquid water discharge.

Abstract: A method and apparatus for afterburning of hydrocarbon with air. Exhaust gas from a process in which hydrocarbon has been evolved is combusted with air to produce reduced NOX emissions. Hydrocarbon fuel is burned in an air mixture at an equivalence ratio of less than 1 oxygen to 1 hydrocarbon fuel (ER<1:1) above a temperature of about 900° C. in a burning zone for a sufficient time to combine substantially all of the oxygen in the fuel/air mixture with disassociated carbon and hydrogen components of the hydrocarbon fuel and to produce carbon dioxide, water, and a portion of unburned light hydrocarbons. The unburned light hydrocarbon gas is cooled in a cooling zone to below a relatively lower temperature of about 800° C. The unburned light hydrocarbon gas is oxidized substantially completely at less than a temperature of about 800° C. so that a reduced amount of thermal NOX results from the combustion and oxidation.

Abstract: A tunnel oven for heating transported carbonaceous materials includes an enclosure having a passage and a transport device for moving solid carbonaceous materials through and along a length of the passage. A direct convection heater is operably connected to the enclosure to heat the solid carbonaceous material as the material is moved along the length of the passage. A temperature controller is operably coupled to the heater to provide one or more selected temperatures along the length of the passage. An atmosphere controller controls the heating atmosphere along the length of the passage so that the surface of the solid carbonaceous material is protected against oxidation.

Abstract: A cyclone separator cooler separates particles from an injected mixture of gas and particulate matter. The inside of the cyclone separator is provided with a flow of liquid. An inside wall of the cyclone separator is at least partially coated with the flowing liquid. Particulate solids in the injected gas and solids mixture are moved to the wall of the cyclone separator by centrifugal force and are removed along with the flow of liquid. The liquid facilitates separation and removal of the particles and also cools the cyclone separator and the gas mixture flowing through it.
