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: Technologies are provided for employing an ion flow to control a combustion reaction. A combustion reaction is supported at a burner or fuel source. One or more electrical signals are applied to an ionizer to generate an ion flow having a first polarity. The ion flow is introduced to the combustion reaction or a reactant at a first location, imparting a corresponding charge to the combustion reaction. The first location is at least intermittently upstream with respect to a reaction front of the combustion reaction. One or more of the electrical signals are applied to a first electrode at a second location downstream of the first location, which provokes a response by the combustion reaction according to the applied charge. The combustion reaction is controlled by selection of the one or more electrical signals.

Abstract: Technologies are presented for applying electrical energy to a combustion reaction to produce agglomerated combustion particulates. For example, a system may include: one or more electrodes configured to apply electrical energy to a combustion reaction; a combustion zone configured to support the combustion reaction of a fuel at a fuel source; and an electrical power source operatively coupled to the one or more electrodes and configured to apply electrical energy to the combustion reaction. The combustion reaction is controlled to produce a distribution of agglomerated combustion particulates characterized by an increase in at least one of an average particulate diameter or an average particulate mass.

Abstract: A burner system includes a nozzle configured to emit a fuel stream for the support of a flame, and first and second electrodes, each configured to apply electrical energy to a flame supported by the nozzle. The first electrode is positioned in a momentum-dominated fluid dynamics region of the flame, while the second electrode is positioned in a buoyancy-dominated fluid dynamics region. Application of charges to the flame via the electrodes can be employed to control flame characteristics in the buoyancy-dominated fluid dynamics region, such as shape and position.

Abstract: A rotary kiln includes a stationary burner and at least one electrode configured to apply an electric field and/or voltage to a flame supported by the stationary burner. The electric field may contain the flame and/or accelerate combustion to shift most heat transfer from the flame from radiation heat transfer to convective heat transfer.
