  • Method and device for operating a steam turbine comprising several no-load or light-load phases
    Patent number: 7028479
    Abstract: A method and a device are for operating a steam turbine in which includes several no-load or light-load phases. All phases are supplied with steam in order to ensure good preheating. The supply of a phase is selected in such a way that the phase produces the least possible output, preferably no output. The enthalpy differential between the entrance to and exit from the phase is thus preferably reduced to zero.

  • Method and device for operating a steam turbine comprising several no-load or light-load phases
    Publication number: 20040088984
    Abstract: The invention relates to a method and a device for operating a steam turbine (10) comprising several no-load or light-load phases (11, 12). All phases (11, 12) are supplied with steam in order to ensure good preheating. According to the invention, the supply of a phase (11) is selected in such a way that said phase (11) produces the least possible output, in particular no output. The enthalpy differential (&Dgr;h) between the entrance (25) to and exit (26) from the phase (11) is thus preferably reduced to zero.
