Abstract

A combustion enhancement system that enhances combustion by converting fuel into hydrogen-enriched fuel within a combustion region, and igniting the hydrogen-enriched fuel by one or more ignitor. A fuel supply provides at least one of fuel or air/fuel mixture to the discharge gap of the ignitor. A method is also provided to dissociate a fuel or air/fuel mixture into hydrogen enriched combusible mixture. The method includes locating the ignition device so that the discharge gap is in device communication with the combustion region, and dissociating at least one of fuel, or air/fuel mixture into hydrogen enriched combustible fuel mixture within the discharge gap. A method of igniting is also provided.
