Abstract

A method for heating a valve configuration of a steam turbine, includes the steps of directing steam to a closed valve of the valve configuration, condensing the steam in the valve, and discharging the condensate. The temperature is kept at the saturated-steam temperature corresponding to the respective steam pressure. The method is in particular suited for keeping a bypass-valve configuration hot. The bypass-valve configuration is intended for bypassing the steam turbine on the steam side. For this purpose, a steam line is connected to the valve configuration. The steam line has an inclined line section with a rising slope or a falling slope directly upstream of the valve configuration. A valve configuration for a steam turbine is also provided.
