The disclosure provides a system and method for production of activated carbon from a coal-originating particulate feed material. Feed material and activating gas are introduced into a reaction chamber, the activating gas being introduced at a velocity above the average terminal velocity of particles within the feed material. Feed material is then entrained in the activating gas such that a recirculating flow path for the feed material is established within the reaction chamber. Activated material may then be recovered from the chamber.

Systems, methods, and devices are provided herein for burners. In one aspect, a burner is provided comprising at least one air pipe; at least one fuel pipe; a plurality of groups of mixing units disposed at a downstream end of the burner, wherein each of the plurality of groups of mixing units is arranged coaxially and adjacent to one another, and each group of mixing units comprises at least one fuel channel connected to the at least one fuel pipe and at least one air channel connected to the at least one air pipe, wherein an outlet of the at least one fuel channel and an outlet of the at least one air channel are angled at a certain degree relative to one another such that the fuel flowing out of the outlet of the at least one fuel channel is mixed with the air flowing out of the outlet of the at least one air channel, thereby achieving multiple-stage mixing of the air and fuel.

Methods and systems convert combustion products to electricity, by efficiently coupling between photovoltaic cells with photons. The photons are emitted from a burning process of a photoluminescence material, the burning process including the chemical reaction of combustion.

A roller system is provided comprising a compressed gas source including a compressed flammable gas, and a roller attachment attached to at least one of the compressed gas source and nozzle.

A well test burner system includes a plurality of burner nozzles, each including an air valve and a well product valve movable between an open position, where air and a well product are allowed to circulate through the burner nozzle to discharge an air/well product mixture, and a closed position, where the air and the well product are prevented from circulating through the burner nozzle. One or more actuation devices are operatively coupled to the air valve and the well product valve to move the air valve and the well product valve between the open and closed positions.

Burner assembly and method for combustion of gaseous of liquid fuel The invention relates to a burner assembly (1) and a method for combustion of gaseous or liquid fuel to heat an industrial furnace (9) having a combustion chamber (2), at least one main combustion air inlet (3) for the supply of preheat-ed combustion air (4) into the combustion chamber (2), a burner (5) with at least one fuel feed (7) and at least one air feed (8) for supply of fuel and primary air into a the combustion chamber (2), wherein the burner (5) is positioned adjacent to a combustion zone of the combustion chamber (2) such that the combustion air (4) flowing into the combustion chamber (2) through the main combustion air inlet (3) is passing the burner (5) in the combustion zone and is then deflected such that the flow of preheated combustion air and the smaller flows of fuel and primary air are flowing mainly in parallel from the burner (5) to the furnace (9), and a control unit for controlling the supply of fuel and maybe primary air into the combustion chamber (2). The control unit is adapted to supply the fuel and/or the primary air from the fuel and/or air feed (7, 8) into the combustion chamber (2) with an exit velocity higher than 150 m/s.

A burner for producing synthesis gas by partial oxidation of liquid or gaseous, carbon-containing fuels in the presence of an oxygen-containing oxidant and a moderator, which burner can be operated uncooled, i.e. without a fluid coolant being passed through the burner, is proposed. Steam or carbon dioxide or else mixtures of these materials are used as moderator. This is achieved by the feed channels being configured so that mixing of the fuel, the moderator and the oxidant occurs only outside the burner.

A combustion device with heat dissipating design includes a burner apparatus and a shield apparatus. The burner apparatus includes a fuel reservoir which has a top defining an opening. The shield apparatus defines a space and the burner apparatus is disposed within the space. The shield apparatus has a bottom and the opening is at a first height in a vertical direction from the bottom. The shield apparatus defines a first through hole extending therethrough and communicating the space and the outside of the shield apparatus and the first through hole is at a second height in the vertical direction from the bottom. The second height is less than the first height.

An inlet assembly for a burner includes an inlet nozzle defining an inlet aperture coupleable with an inlet conduit providing an effluent gas stream for treatment by the burner, a non-circular outlet aperture, and a nozzle bore extending along a longitudinal axis between the inlet aperture and the outlet aperture for conveying the effluent gas stream from the inlet aperture to the outlet aperture for delivery to the combustion chamber of the burner.
