Abstract: According to embodiments, a co-fired or multiple fuel combustion system is configured to apply an electric field to a combustion region corresponding to a second fuel that normally suffers from poor combustion and/or high sooting. Application of an AC voltage to the combustion region was found to increase the extent of combustion and significantly reduce soot evolved from the second fuel.

Abstract: A multijet burner system includes a plurality of fuel nozzles, each configured to support a respective flame, a plurality of charge electrodes, each positioned and configured to apply a charge potential to a fluid flow corresponding to a respective one of the plurality of fuel nozzles, and a charge controller operatively coupled to each of the plurality of charge electrodes and configured to control a voltage potential applied to each respective charge electrode. By selecting the magnitude and polarity of a charge potential applied to individual ones of the flames of the plurality of burners, the flames can be made to change positions, move to selected positions, and redistribute themselves within a volume.

Abstract: An oscillating combustor may support a time-sequenced combustion reaction having rich and lean phases. The rich and lean phases may be determined according to a flame position relative to a diverging fuel jet. The flame location may be modulated responsive to an interaction between applying a constant voltage or charge rate to a fuel stream or flame, and modulating continuity between a conductive or semiconductive flame holder and an activation voltage.
