Abstract

See full text

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.
