A combustion enhancement system that enhances combustion by providing enriched with hydrogen-enriched fuel to a combustion region, and igniting the combustible hydrogen-enriched fuel by one or more ignitor is disclosed. The ignitor has a first electrically conductive surface spaced from a second electrically conductive surface to form a gap in direct communication with the combustion region. The ignitor includes a housing having a first portion and a second portion, a first electrically conductive surface proximate the second portion of the housing, a second electrically conductive surface proximate the second portion of the housing and spaced from the first electrically conductive surface to form a discharge gap. The discharge gap has a discharge initiation region. A fluid passage extends between the first portion and the second portion, the fluid passage being in communication with the discharge gap. An insulator has a surface exposed to the discharge gap. A fuel supply provides at least one of fuel or air/fuel mixture to the gap. A controller provides at least one electrical pulse between the first conductive surface and second conductive surface that dissociates at least one of fuel or air/fuel mixture passing through the discharge gap. A method is also provided to dissociate a fuel or air/fuel mixture for the system. The method includes locating the ignition device so that the discharge gap is in direct communication with the combustion region, and dissociating at least one of fuel, air/fuel or combustible fuel mixture by the discharge gap. A method of igniting is also provided. The method includes passing an electrical pulse of first voltage at a first current to the first electrically conductive surface and a second electrically conductive surface, the first electrically conductive surface has a first length, the second electrically conductive surface has a second length, the shorter of the first and second lengths defines a discharge gap length, the shortest distance between the first electrically conductive surface and the second electrically conductive surface define a discharge gap width, where a ratio of the discharge gap width to the discharge gap length being greater than one to three; and passing a second electrical pulse less than or equal to the first voltage at a second current greater than or equal to the first between the discharge gap. |
