Gas turbine with a plurality of burners and a fuel distribution system, and a method for balancing a fuel distribution system

Abstract

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.
