    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.

    Abstract: A gas turbine may include turbine blades configured to improve stream adhesion by selectively attracting or reducing repulsion of charged particles carried by a combustion gas stream. According to an embodiment, a gas turbine may include a combustor configured to output a combustion gas stream, the combustion gas stream being controlled or driven to at least intermittently or periodically include charged particles having a first sign. For example the first sign may be positive during at least an instant. The gas turbine also includes at least one turbine configured to receive the combustion gas stream (carrying the charged particles at least intermittently or periodically). The turbine includes at least one turbine stage having turbine blades. Each turbine blade includes a repelling surface configured to be at least intermittently or periodically held or driven to a repelling voltage having a polarity the same as the charged particles having the first sign.

    Abstract: According to an embodiment, an electrode system for a burner may include a thermally coupled electrode configured to apply an electric field to a region corresponding to a flame or combustion gas produced by the flame and to receive heat from the flame or the combustion gas. A cooling apparatus may be operatively coupled to the thermally coupled electrode and configured to remove the heat received by the electrode from the flame or the combustion gas. According to another embodiment, a method of cooling an electrode subject to heating by a flame or a combustion gas produced by the flame may include applying an electric field to a flame or combustion gas produced by the flame with an electrode.

    Abstract: A combustion system includes a fuel distributor configured to output a fuel, an oxidant source configured to output an oxidant, and a mixing tube defining a mixing volume aligned to receive the fuel and oxidant. The mixing tube is shaped to convey the fuel and the oxidant through the mixing volume at a bulk velocity higher than a flame propagation speed. The combustion system includes a flame holder aligned to receive the mixed fuel and oxidant and to support a combustion reaction of the fuel and the oxidant.

    Abstract: A combustion system includes a perforated flame holder, a preheating fuel distributor, a main fuel distributor, an oxidant source, an array of sensors, and a controller. The oxidant source outputs an oxidant. The preheating fuel distributor supports a preheating flame configured to preheat the perforated flame holder by outputting a preheating fuel when the combustion system is in a preheating state. The main fuel source outputs a main fuel in the standard operating state. The perforated flame holder is configured to support a combustion reaction of the main fuel and the oxidant in the standard operating state. The sensors are configured to sense parameters of the preheating flame and the perforated flame holder and to output sensor signals to the controller. The controller executes software instructions that include adjusting the flow of the main fuel, the preheating fuel, and the oxidant responsive to the sensor signals.
