Abstract
A combustion chamber for a gas turbine is provided. The combustion chamber has a pilot burner device, a fuel injector and an ignitor unit. The pilot burner device has a pilot body with a pilot surface which is facing an inner volume of the combustion chamber. The fuel injector has a fuel outlet for injecting a fuel into the inner volume. The ignitor unit is adapted for igniting the fuel inside the inner volume, wherein the ignitor unit is arranged at the pilot surface such that fuel which passes the ignitor unit is ignitable. The pilot body includes a recess, wherein the fuel outlet is arranged within the recess.
Claims16
A combustion chamber for a gas turbine, the combustion chamber comprising
- a pilot burner device comprising a pilot body with a pilot surface which is facing an inner volume of the combustion chamber, wherein the pilot burner device further comprises a centre axis,
- a fuel injector comprising a fuel outlet for injecting a fuel into the inner volume, and
- an ignitor unit for igniting the fuel inside the inner volume,
- wherein the ignitor unit is arranged at the pilot surface such that fuel which passes the ignitor unit is ignitable,
- wherein the pilot body comprises a recess, wherein the fuel outlet is arranged within the recess, and
- wherein the recess is located off-centred from the centre axis.
A method for operating a combustion chamber, the method comprising
- injecting a fuel into an inner volume of the combustion chamber by a fuel injector,
- wherein the combustion chamber comprises a pilot burner device comprising a pilot body with a pilot surface which is exposable to a flame in the inner volume of the combustion chamber, and
- igniting the fuel inside the inner volume by an ignitor unit.
- wherein the ignitor unit is arranged at the pilot surface such that fuel which passes the ignitor unit is ignitable,
- wherein the fuel outlet is formed for directing the fuel in the direction to the ignitor unit,
- wherein the pilot body comprises a recess, and wherein the fuel outlet is arranged inside the recess such that the fuel outlet is arranged recessed within the pilot body.
