Abstract
An apparatus for retrofitting a coal-fueled burner of, e.g., a furnace, with a gas-fueled burner system for enhancing flame radiation of a gas flame. The gas-fueled burner system 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 onto the flame. The flame responds to the time-varying charge by increasing its luminosity and emissivity.
