Claim:
1. A combustion system, comprising: a burner configured to discharge fuel into a combustion volume in which the fuel and an oxidizer are ignited to generate a flame; at least one charging electrode positioned proximate to the flame, the at least one charging electrode configured to emit charges into the flame to generate a charged flame exhibiting a net charge and/or polarity; one or more flame anchoring electrodes disposed adjacent to the burner and proximate to a base portion of the charged flame; and at least one first voltage power supply electrically coupled to the at least one charging electrode, wherein the at least one charging electrode provides charges to the flame responsive to being biased by the first voltage power supply; and at least one second voltage power supply electrically coupled to the one or more flame anchoring electrodes, the at least one second voltage power supply configured to apply one or more electrical potentials to each of the one or more flame anchoring electrodes so that a base of the charged flame is stably positioned at a predetermined location, wherein the position of the base of the charged flame is spaced from the burner at the predetermined location.
