Abstract: A method and gas turbine are provided for the reliable purging of an exhaust gas recirculation line of the gas turbine with exhaust gas recirculation without the use of additional blow-off fans. A blow-off flow of the compressor is used for the purging of the exhaust gas recirculation line. The gas turbine can include at least one purging line which connects a compressor blow-off point to the exhaust gas recirculation line.

Abstract: The invention relates to a method for the start of a power plant installation (10), which comprises a gas turbine (2), a generator (18) coupled to the gas turbine (2), and a frequency converter (27) to feed current into an electrical grid (1). In accordance with the method, during the start of the gas turbine (2), the generator (18) is connected to the electrical grid (1) via the frequency converter (27) before the operating rotational speed of the gas turbine (2) is reached, wherein the frequency converter (27) is controlled such that it generates an output current with the grid frequency. The invention further relates to a power plant installation (10) for the execution of such a method.

Abstract: The present disclosure refers to a method for operating a gas turbine with sequential combustors having a first-burner, a first combustion chamber, and a second combustor arranged sequentially in a fluid flow connection. To minimize emissions and combustion stability problems during transient changes when the fuel flow to a second combustor is initiated the method includes the steps of increasing the second fuel flow to a minimum flow, and reducing the first fuel flow to the first-burner of the same sequential combustor and/or the fuel flow to at least one other sequential combustor of the sequential combustor arrangement in order keep the total fuel mass flow to the gas turbine substantially constant. Besides the method a gas turbine with a fuel distribution system configured to carry out such a method is disclosed.
