Burner and method for operating a burner

A burner, comprising:

• a burner outlet opening including at least two sectors, each sector including a fuel nozzle;
• at least two separate fuel supply lines leading to the plurality of fuel nozzles of different sectors;
• and
• a facility for setting a fuel mass flow flowing through the respective fuel supply line,
• wherein the facility includes a plurality of valves arranged in the respective fuel supply line that may be regulated,
• wherein the plurality of valves are separately controlled such that in full-load operation an even supply of fuel is provided to all sectors to produce a homogenous temperature distribution,
• wherein in a part-load operation hotter and colder zones are able to be created in the combustion chamber, a greatest quench effect occurs in the hotter zones,
• 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,
• wherein a first plurality of fuel nozzles are assigned to a first sector arranged along the tangential direction of the burner and a second plurality of second fuel nozzles are assigned to a second sector arranged along the radial direction of the burner,
• wherein the facility for setting the fuel mass flow is operable to regulate the valves arranged in the respective fuel supply lines such that the first plurality of fuel nozzles is supplied with less fuel than the second plurality of fuel nozzles at said part load.

A gas turbine, comprising:

• a burner, the burner comprising:
• a burner outlet opening including at least two sectors, each sector including a fuel nozzle;
• at least two separate fuel supply lines leading to the plurality of fuel nozzles of different sectors;
• and
• a facility for setting a fuel mass flow flowing through the respective fuel supply line,
• wherein the facility includes a plurality of valves arranged in the respective fuel supply line that may be regulated,
• wherein the plurality of valves are separately controlled such that in full-load operation an even supply of fuel is provided to all sectors to produce a homogenous temperature distribution,
• wherein in a part-load operation hotter and colder zones are able to be created in the combustion chamber, a greatest quench effect occurs in the hotter zones,
• wherein the burner is one of a plurality of burners arranged circumferentially in a combustion chamber, about a central axis of the combustion chamber,
