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 charge electrode configured to impart a time-varying majority charge on a flame and a shape electrode located outside the flame may be driven synchronously by a voltage source through time varying voltage(s). The flame may be flattened or compressed responsive to an electric field produced by the shape electrode acting on the charges imparted on the flame.
