Claim:
A method for operating a burner, comprising: providing a burner outlet opening including at least two sectors; assigning each sector a plurality of fuel nozzles; and supplying a fuel to a plurality of fuel nozzles of different sectors separately, wherein during a full load operation, essentially an even supply of the fuel is provided to all sectors to produce a homogenous temperature distribution, wherein during a part load operation, hotter and colder zones are created in a combustion chamber, with the hotter zones placed where the greatest quench effect would otherwise be expected, wherein the burner is one of a plurality of burners arranged circumferentially in a combustion chamber, about a central axis of the combustion chamber, wherein the burner has a radial direction and a tangential direction in relation to the central axis, and wherein a first plurality of fuel nozzles that are assigned to a first sector arranged along the tangential direction of the burner are supplied with less fuel at said part load than a second plurality of fuel nozzles that are assigned to a second sector arranged along the radial direction of the burner.
