    CPC classification number: F23C99/001

    Abstract: A combustion system includes a fuel nozzle, a charge source, a discharge electrode, and a voltage supply coupled to the charge source and discharge electrode. The charge source is configured to apply a polarized charge to a flame supported by the nozzle, and the discharge electrode is configured to attract a flame-front portion of the flame to hold the flame for flame stability. The discharge electrode can be toroidal in shape, positioned coaxially with the nozzle downstream from the nozzle. The voltage supply is configured to hold the charge source at a charge potential and the discharge electrode at the discharge potential. The nozzle can be configured to apply the polarized charge to a fuel stream emitted by the nozzle, whereafter the charge is passed to the flame upon combustion of the fuel.

    Abstract: A combustion system includes a fuel nozzle and first and second electrodes. An electric charge is applied to a flame supported by the nozzle via the first electrode. An electrical potential applied to an aerodynamic surface of the second electrode. The electrically charged flame reacts to the electrical potential according to the respective magnitudes and polarities of the charge applied to the flame and the electrical potential applied to the aerodynamic surface. Where the polarities are the same, the flame is repelled by the aerodynamic surface, and where the polarities are in opposition, the flame is pulled into contact with the aerodynamic surface by the electrodynamic attraction.

    Abstract: A combustion reaction is supported. Charge carriers traveling in an ion flow path are ionized by a plurality of ionizer stages along the ion flow path. The ionized charge carriers are drawn from components of the combustion reaction, and are introduced to the combustion reaction. A charge is imparted to the combustion reaction by the ionized charge carriers. Electrical energy can then be applied to the combustion reaction, which responds according to the charge imparted by the ions.

    Abstract: A solid fuel burner may include a system for electrodynamic homogenization. One or more electrodes may apply an electric field to burning solid fuel or a region proximate the burning solid fuel. The electric field causes mixing and homogenization of volatilized fractions of the solid fuel, combustion gases, and air. The improved mixing and homogenization may reduce emission of carbon monoxide (CO), reduce emission of oxides of nitrogen (NOx), reduce oxygen in flue gas, increase temperature of flue gas, and/or allow for a larger grate surface.
