Abstract: A method for controlling a combustion reaction includes introducing fuel and oxidizer into a combustion volume at a ratio that is outside a range defined by an upper flammability or stability limit and a lower flammability or stability limit of the fuel, and producing a modified range defined by a modified upper flammability or stability limit and a modified lower flammability or stability limit of the fuel, by applying an electric field across a flame supported by the fuel and oxidizer, the ratio falling within the modified range.

Abstract: A perforated flame holder and burner including a perforated flame holder provides reduced oxides of nitrogen (NOx) during operation. The perforated flame holder includes a pattern of elongated apertures extending between a proximal and a distal surface of the flame holder relative to a fuel nozzle. The perforated flame holder can provide a significantly reduced flame height while maintaining heat output from the burner.

Abstract: A down-fired flame burner including a flame charger and one or more field electrodes configured to control flame shape and/or heat transfer to a chemical reactor is presented. Also described is a method for providing process heat includes projecting a down-fired flame in a heating volume, electrically charging the flame to carry a majority charge, and applying an electric field proximate the down-fired flame to control flame shape, heat transfer from the flame, or flame shape and heat transfer from the flame, and applying heat from the flame to a chemical reactor.
