Abstract

A method for operating a steam power station is provided. The steam turbine power station includes at least one steam turbine and a process steam consumer, wherein a steam mass flow is subdivided into a first partial mass flow and a second partial mass. In a first operating state, the first partial mass flow is supplied to the steam turbine and the second partial mass flow is supplied to the process steam consumer. In a second operating state, at least part of the second partial mass flow is supplied to the steam turbine at least after the first turbine stages. A steam power station is also provided.
