Abstract: A combustion system is provided that includes a fuel nozzle configured to support a combustion reaction, and an electrode positioned to apply an electrical charge to the combustion reaction. A power converter is positioned to receive heat produced by the combustion reaction and to convert a portion of the received heat to electrical energy. A combustion system controller is configured to provide the electrical charge to the electrode, using energy drawn either from the power converter or from a power storage element, depending on an amount of power being produced by the power converter and on a state-of-charge of the power storage element. The controller is further configured to use surplus energy generated by the power converter to recharge the power storage element.

Abstract: In an embodiment, a combustion system includes a burner, at least one charging electrode, flame anchoring electrode(s), and at least one voltage power supply. The burner is configured to discharge fuel into a combustion volume in which the fuel and an oxidizer are ignited to generate a flame. The charging electrode is positioned proximate to the flame. The charging electrode provides charges to the flame to generate a charged flame. The flame anchoring electrode(s) are disposed adjacent to the burner and proximate to a base portion of the charged flame. The voltage power supply is electrically coupled to each of the flame anchoring electrode(s) and the charging electrode. The at least one voltage power supply applies one or more electrical potentials to each of the flame anchoring electrode(s) so that the charged flame is anchored at a predetermined location.
