In a gas turbine (10) with a plurality of individual burners (B1, . . . , B6; Bn) which are connected to a fuel distribution system (21) and are supplied with fuel from a common fuel feed (28) via the fuel distribution system (21), there being provided, within the fuel distribution system (21), means by which the fuel mass flows to the individual burners (B1, . . . , B6; Bn) can be varied in order to improve the operating parameters of the gas turbine (10), an improvement in the operating parameters is achieved in a simple way in that a fixed throttle member, determining the fuel mass flow to at least one of the burners (B1, . . . , B6; Bn), is arranged in the fuel distribution system (21) upstream of the at least one burner, and in that the reduction in cross section of the throttle member is selected in such a way that existing inequalities in the fuel distribution system (21) as regards the fuel mass flows to the individual burners (B1, . . . , B6; Bn) are reduced.

[ What is claimed as new and described to be secured by Letters Patent of the United States is:] [1.]1. A gas turbine comprising:a plurality of individual burners;a fuel distribution system including a common fuel feed, the plurality of burners connected to the fuel distribution system for being supplied with fuel from the common fuel feed via the fuel distribution system;a fixed throttle member arranged in the fuel distribution system upstream of at least one of the plurality of burners and determining the fuel mass flow to the at least one of the plurality of burners, the fixed throttle member having a reduction in cross section selected to reduce inequalities in the fuel mass flows through the fuel distribution system to the individual burners;wherein the throttle member is a first throttle member and the at least one burner is a first burner, and further comprising a second throttle member having a cross section different from the cross section of the first throttle member, the second throttle member arranged in the fuel distribution system upstream of a second burner of the plurality of burners.
