Method for operating a gas turbine combustion chamber including a plurality of burners arranged in groups

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 ( 4 I , 4 II). A common oxidant supply ( 5 ) is provided for all the burners ( 3 ). A common first fuel supply ( 7 ) is provided for the burners ( 3 I) belonging to the first burner group ( 4 I). A common second fuel supply ( 9 ) and a common additional fuel supply ( 11 ) are provided for the burners ( 3 II) belonging to the second burner group ( 4 II). A first fuel stream ( 8 ) is fed to the burners ( 3 I) belonging to the first fuel group ( 4 I), in such a manner that a lean fuel/oxidant mix is established. A second fuel stream ( 10 ) is fed to the burners ( 3 II) belonging to the second burner group ( 4 II) in such a manner that a lean fuel/oxidant mix is established. The first fuel stream ( 8 ) for each burner ( 3 I) belonging to the first burner group ( 4 I) is selected to be greater than the second fuel stream ( 10 ) for each burner ( 3 II) belonging to the second burner group ( 4 II). In addition, an additional fuel stream ( 12 ) is fed to the burners ( 3 II) belonging to the second burner group ( 4 II).
