Abstract (en)
[origin: WO0192689A1] 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 ( DELTA h) between the entrance (25) to and exit (26) from the phase (11) is thus preferably reduced to zero.
