Abstract: A lance is presented for introducing fuel into a second burner of a combustion chamber of a gas turbine installation with sequential combustion, having a first and a second combustion chamber. The lance includes a foot and a shank which projects from it. In an installed state of the lance the foot extends perpendicularly or at an angle to a main flow direction of the burner. The shank extends centrally in the burner and generally parallel to the main flow direction. At least one projecting arm, having at least one nozzle for introducing fuel, is arranged such that it extends from the shank. A respective end of the at least one arm is oriented in the main flow direction and extends generally parallel to the main flow direction.

Abstract: In a method for reliably removing liquid fuel from the fuel system of a gas turbine after shutting down the same, in the case of which fuel system liquid fuel is fed via at least a first feeder line in normal operation of the gas turbine to a burner and injected there into a combustion chamber via fuel nozzles, a high reliability against explosion and coking is achieved in a simple way by virtue of the fact that the liquid fuel is flushed from the fuel system by the use of an inert auxiliary medium.
