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.
