Abstract (en)

[origin: EP1365110A1] The method involves determining at least one internal pressure and internal and external temperature of at least one steam carrying component during operation, determining a spatial temperature distribution, deriving a comparison stress for the steam-carrying component, comparing with an upper mechanical load stress, determining a limiting steam pressure desired value if the comparison stress is higher and setting a steam valve accordingly. The method involves determining at least one internal pressure and at least one internal and external temperature of at least one steam carrying component (7) during operation, determining a spatial temperature distribution, deriving a comparison stress (Vs) for the steam-carrying component, comparing with an upper mechanical load stress (Mgs) and determining a limiting steam pressure desired value (Gd) if the comparison stress is higher and setting a steam valve (10) accordingly. AN Independent claim is also included for a device for operating a steam power plant, especially in partial load mode.
