Abstract

A method for regulating a steam bypass valve is provided. The bypass valve is arranged in a steam line and the steam line includes a device for spraying water. The equation,is used to determine when to close the steam bypass valve. The steam bypass value is closed when tRest,0 is smaller than a value Δt. An actual volume of water {dot over (m)}W,IST, a desired volume of water {dot over (m)}W,SOLL and a maximum water-volume deficiency FBmax are used in the equation.
