摘要： An exemplary method is disclosed for operating a gas turbine power plant with exhaust gas recirculation, in which the exhaust gas recirculation is, for example, disengaged during starting and shutting down of the gas turbine, and in which the engaging or disengaging of the exhaust gas recirculation can be carried out in dependence upon an operating state of the gas turbine. An exemplary gas turbine power plant with exhaust gas recirculation is also disclosed which can include a control element, the closing speed of which is such that the control element can be closed within a time which is less than a time for exhaust gases to flow from the turbine through an HRSG.

摘要： A method is provided for operating a gas turbine power plant with exhaust gas recirculation, in which, based upon the operating state of the gas turbine a setpoint concentration of at least one constituent in an exhaust gas flow and/or in the intake flow of the gas turbine after adding the recirculated exhaust gases is determined. The actual concentration of the at least one constituent in the exhaust gas flow and/or in the intake flow is measured and a control element for controlling the recirculation flow is controlled based upon the setpoint/actual deviation. Also provided is a gas turbine power plant with exhaust gas recirculation and includes a controller, in which a setpoint concentration of at least one constituent in an exhaust gas flow or in the intake flow of the gas turbine is determined, and a measuring instrument for measuring the actual concentration of the at least one constituent.
