ABSTRACT:
A method for operating a combustion chamber (1) for a gas turbine. The combustion chamber (1) has a combustion space (2) and a plurality of burners (3), which are each arranged at an inlet (13) of the combustion space (2). The burners (3) are divided into two burner groups (4I, 4II). A common oxidant supply (5) is provided for all the burners (3). A common first fuel supply (7) is provided for the burners (3I) belonging to the first burner group (4I). A common second fuel supply (9) and a common additional fuel supply (11) are provided for the burners (3II) belonging to the second burner group (4II). A first fuel stream (8) is fed to the burners (3I) belonging to the first fuel group (4I), in such a manner that a lean fuel/oxidant mix is established. A second fuel stream (10) is fed to the burners (3II) belonging to the second burner group (4II) in such a manner that a lean fuel/oxidant mix is established. The first fuel stream (8) for each burner (3I) belonging to the first burner group (4I) is selected to be greater than the second fuel stream (10) for each burner (3II) belonging to the second burner group (4II). In addition, an additional fuel stream (12) is fed to the burners (3II) belonging to the second burner group (4II).
