Abstract: A method for starting a steam turbine system having a steam generator, a steam turbine which is connected to the steam generator and includes at least two turbine stages that, at the time of starting the steam turbine system, have different outlet temperatures, a condenser connected to the steam turbine and a consumer driven by the steam turbine, in which the steam generated in the steam generator is used to start the steam turbine, wherein, until the steam generated in the steam generator reaches a predetermined temperature that at least corresponds to the temperature requirement of the turbine stage with the higher outlet temperature, only the turbine stage with the lower outlet temperature is operated, and in that the turbine stage with the higher outlet temperature is brought on-line only once the predetermined temperature has been reached.

Abstract: The invention relates to a method for operating a steam turbine, the steam turbine being accelerated to a nominal speed by a device, such as, for example, a gas turbine or a generator. The steam turbine is charged with steam only when the steam has certain steam parameters, until the steam has reached the certain steam parameters, where the steam turbine is accelerated to a rated speed by the device.
