Apparatus and method for enhancing combustion comprises an enclosure defining an opening for introduction of a gas and openings for the introduction of air, with a nozzle in the opening for introduction of a fuel gas into the enclosure. First and second electrodes are located in the enclosure, the first and second electrodes being coated with dielectric material, and being connected to an electrical power supply. With electrical power applied to the first and second electrodes and with the fuel gas sprayed into the enclosure, an atmospheric pressure plasma created by a dielectric barrier discharge is produced in the enclosure that cracks the fuel gas prior to its mixing with air introduced through the openings for the introduction of air.
 The present invention generally relates to combustion processes, and, more specifically, to processes that enhance the efficiency of combustion processes. This invention was made with Government support under Contract No. W-7405-ENG-36 awarded by the U.S. Department of Energy. The Government has certain rights in the invention.
