  • Independently actuated control valves for steam turbine
    Patent number: 4604028
    Abstract: A control system for a steam turbine employs complementary-sized nozzle groups receiving steam in a sequence which employs the smallest possible sized group receiving steam from a control valve of the smallest possible capacity as the governing valve. All other control valves remain either fully open or fully closed. An optimum path may be followed to select a highest-efficiency transition between valve combinations.
