Abstract:
1. A method for combusting gaseous fuel with a gaseous oxidant in a combustor comprising: providing gaseous oxidant and a combustible gaseous fuel; mixing the gaseous oxidant and gaseous fuel, where the gaseous oxidant has a velocity relative to the fuel which is sufficient to cause turbulent mixing with the fuel; introducing a stable, field generated source of charged particles at the corona initiation source at a sharp contact point of the flame to an end of a fuel feed tube to increase a charged particle density; and combusting the gaseous oxidant and fuel in the region of a combustion flame and an electric field, where the electric field produces an electrical stress resulting in local breakdown of the mixture of gaseous oxidant and fuel, and a corona discharge that in turn generates intimate turbulent mixing of the gaseous oxidant and fuel.
