    • A method for starting a combined cycle power plant (1) includes loading the gas turbine unit (2), providing a starting temperature (Tsrart) for the steam supplied to the steam turbine (5), while the control valve (7) is regulated controlling the temperature of the steam at a temperature substantially equal to the starting temperature (Tstart) at a position (P2) downstream of the control valve (7) and upstream of the rotor (8), when the control valve (7) is substantially fully open, supplying steam to the steam turbine (5) at the starting temperature (Tstart). The steam temperature is controlled by controlling the steam temperature upstream of the control valve (7) in accordance with the temperature drop caused by the control valve (7) when the steam passes through it.

    • A steam turbine (10), especially in the form of a double-flow low-pressure steam turbine, includes a rotor (11) which is rotatably mounted around an axis (21) and which is concentrically enclosed with a spacing by an inner casing (13), forming annular steam passages (28, 29), and which has a multiplicity of rotor blades (12) which project into the steam passages (28, 29), wherein the inner casing (13) supports a multiplicity of stator blades (12) which project into the steam passages (28, 29) and which, for feeding steam to the steam passages (28, 29), has an inlet duct (15) which is directed around the axis (21) and tapers in the flow cross section. With such a steam turbine, the production is simplified by the inner casing (13) being formed as a welded construction, in which blade carriers (14), which delimit the steam passages (28, 29) and are produced as cast parts, are welded to additional forged or rolled steel elements (20) for fastening the stator blades (12′).
