The invention relates to a method for starting a gas and steam turbine system which comprises a gas turbine system which comprises at least one gas turbine, in addition to at least one steam turbine system which comprises at least one steam turbine and at least one steam system. Heat produced by the working fluid and which is released in the gas turbine is guided to the steam system in order to produce steam which drives the steam turbine. According to the invention, during starting, the gas turbine is started prior to the steam turbine and the steam turbine is started in the presence of the first steam in the system and is impinged upon by said steam.

Method for starting up a gas and steam turbine system

A method for prior determination of a life consumption of individual components in a fossil-fuelled power generating installation, with respect to a load cycling process to be carried out is provided. An apparatus is also provided for prior determination of a life consumption of individual components in a fossil-fuelled power generating installation, with respect to a load cycling process to be carried out. Actual variables which characterize the state of the power generating installation before a load cycling process are determined. A driving gear of the power generating installation which creates the load cycling process is set in advance. The load cycle time is calculated based upon the driving gear and the characterizing variables. A predicted life consumption for at least one of the individual components for the selected driving gear is also calculated.
