Abstract
A steam turbine comprises a steam turbine casing, a rotor, and at least one compliant plate seal assembly situated between the casing and the rotor. The compliant plate seal assembly comprises a supporting member being stationary with respect to the casing, a plurality of plate members movably mounted to the supporting member and extending towards the rotor, each plate member being inclined with respect to a rotation direction of the rotor, and an actuator for selectively exerting a pressure to retract the plate members in a direction away from the rotor.
