Abstract
An injection system, injector, and associated method are provided for injecting and combusting combustion fluids in a combustion chamber. The system includes a faceplate that faces the combustion chamber and a plurality of injectors that extend through the faceplate. Each of the injectors has an injector body with an outlet side. A fuel bore extends from a fuel bore inlet to a fuel bore outlet located at the outlet side of the injector. Each injector also includes a swirler chamber with at least one inlet for receiving steam and an oxidizing fluid and an oxidizing fluid outlet located on the injector outlet side. A converging channel extends from the oxidizing fluid outlet to the swirler chamber, and the converging channel converges relative to the fuel bore so that steam and oxidizing fluid exiting the injector through the oxidizing fluid outlet impinge on a stream of fuel in the combustion chamber flowing from the fuel bore.
