Patent ID: 8549860

Claim:
A method for combustion of a hydrogen-rich, gaseous fuel in combustion air in a double-cone burner of a gas turbine, the method comprising: injecting the hydrogen-rich, gaseous fuel at least partially isokinetically with respect to the combustion air such that the hydrogen-rich, gaseous fuel is injected at least partially in the same direction and at least partially at the same velocity as the combustion air, wherein the hydrogen-rich, gaseous fuel is injected into the combustion air through one or more elongated rounded openings, wherein a main axis of each of the elongated rounded openings is oriented parallel to a local air flow, and wherein the hydrogen-rich, gaseous fuel is injected through the elongated rounded openings at a slant that, in relation to a vertical of a vortex air flow, is oriented in a direction of the vortex air flow.
