Patent ID: 8800297

Claim:
A method for starting up a gas and steam turbine system having a gas turbine system containing a gas turbine and a steam turbine system containing a steam turbine and a steam system, comprising: supplying a waste heat of a working medium of the gas turbine to the steam system to produce steam for driving the steam turbine; and starting up and accelerating the steam turbine when a first steam is present in the steam system via impingement of the first steam upon the turbine; wherein the first steam is generated in the steam system by the waste heat from the gas turbine, wherein the steam turbine is started with the first steam at the earliest possible time without waiting for stationary states in the steam system, wherein during the startup operation the steam system is tuned such that the steam pressure increases continuously, and wherein the steam system is tuned via at least one steam diverter station of the steam system, and no diverter station leading to a bypassing of the steam turbine is opened in the steam system during the entire system startup.
