A combustion chamber of a gas turbine combusts a fuel in the presence of combustion air. The combustion chamber is configured as dual-fuel combustion chamber, wherein the combustion chamber, in a gas fuel operating mode, is supplied with a mixture of a gaseous fuel and combustion air via a main swirl body. In a liquid fuel operating mode, the combustion chamber is supplied with a liquid fuel via an atomization apparatus and combustion air via the main swirl body. The atomization apparatus has an atomization lance with an atomization nozzle centrally arranged with respect to a longitudinal center axis of a prechamber of the combustion chamber. The atomization nozzle of the central atomization lance includes a swirl chamber and, downstream of the swirl chamber, a nozzle orifice. The swirl chamber is supplied with the liquid fuel via a radial swirl generator and an axial swirl generator.

Combustion chamber of a gas turbine, gas turbine and method for operating the same

An assembly for a gas turbine having a combustion chamber, a swirler, a combustion zone in the combustion chamber, and an air feed. In a transition region from the air feed to the swirler that is flowed through by the air, a plenum is formed and the assembly adjoining the plenum has the swirler, the combustion chamber, and a cover closing the combustion chamber. The assembly has an air conduction channel designed to conduct part of the air flow flowing into the assembly into the combustion chamber, so that the air flow leading through the air feed is divided into a main flow leading through the swirler into the combustion zone and a bypass flow leading past the combustion zone.
