Abstract:
A horizontally-fired flame burner includes a flame holder positioned laterally from the burner. The flame holder includes a plurality of perforations that collectively confine a combustion reaction of the burner to the flame holder.
Abstract:
According to embodiments, a co-fired or multiple fuel combustion system is configured to apply an electric field to a combustion region corresponding to a second fuel that normally suffers from poor combustion and/or high sooting. Application of an AC voltage to the combustion region was found to increase the extent of combustion and significantly reduce soot evolved from the second fuel.
Abstract:
An oscillating combustor can support a time-sequenced combustion reaction having rich and lean phases by applying a variable voltage charge to a fuel stream or flame that flows adjacent to a conductive or semiconductive flame holder held in electrical continuity with an activation voltage.
Abstract:
An inertial electrode launcher may be configured to project charged particles or a voltage comprising an inertial electrode proximate a flame or combustion gas produced by the flame.
Abstract:
A multijet burner system includes a plurality of fuel nozzles, each configured to support a respective flame, a plurality of charge electrodes, each positioned and configured to apply a charge potential to a fluid flow corresponding to a respective one of the plurality of fuel nozzles, and a charge controller operatively coupled to each of the plurality of charge electrodes and configured to control a voltage potential applied to each respective charge electrode. By selecting the magnitude and polarity of a charge potential applied to individual ones of the flames of the plurality of burners, the flames can be made to change positions, move to selected positions, and redistribute themselves within a volume.
Abstract:
A burner system and a retrofit flame control system for an existing burner system are disclosed. The burner system may include burner components, electrodynamic components, and a data interface. The data interface may receive a command for controlling the burner components and prepare a command for controlling the electrodynamic components at least partially based on the command for controlling the burner components.
Abstract:
An electrically stabilized burner is configured to support a combustion reaction such as a combustion reaction substantially at a selected fuel dilution and with a mixing rate selected to maximize the reaction rate without quenching the combustion reaction.

Abstract:
Embodiments are directed to a gasifier that electrodynamically agitates charged chemical species in a reaction region of a reaction vessel of a gasifier and related methods. In an embodiment, a gasifier includes a reaction vessel configured to gasify at least one hydrocarbon-containing feed material to synthesis gas. The reaction vessel includes an inlet(s) for receiving a gasification medium that reacts with the at least one hydrocarbon-containing feed material and an outlet for allowing the synthesis gas to exit from the reaction vessel, and a reaction region. The gasifier includes at least one electrode positioned to be in electrical communication with the reaction region, and a voltage source operatively coupled to the at least one electrode. The voltage source and the at least one electrode are cooperatively configured to generate a time varying electric field in the reaction region to effect electrodynamic mixing of charged chemical species therein during gasification.
Abstract:
A premixed fuel and air combustion system includes an anti-flashback electrode configured to repel a charge concentration in a combustion fluid and reduce or prevent the flame from flashing back into a mixer.
