Abstract: An apparatus for enhancing flame radiation includes a flame charging system and an electrically isolated electrode. A time-varying voltage is applied to the flame charging system and the flame charging system imparts a corresponding time-varying charge or time-varying voltage onto the flame. The flame responds to the time-varying charge or voltage by increasing its luminosity.

Abstract: A burner includes a flame positioning mechanism. The flame positioning mechanism includes a flame charger, a plurality of electrodes placed a respective distances along a fuel stream propagation path, and an electrode switch configured to place a subset of the plurality of electrodes into electrical continuity with a holding voltage. Current flow between the flame charge and the holding voltage anchors the flame to an electrode placed into electrical continuity with the holding voltage.
