Abstract: A steam turbine is provided. The steam turbine includes a housing and a steam inlet configured to discharge a primary steam flow within the housing. A stator is coupled to the housing and a rotor is coupled to the housing and located within the stator. The rotor and the stator are configured to define a primary flow path there between and in flow communication with the primary steam flow. The steam turbine includes a seal assembly coupled to the housing. The seal assembly includes a packing head and a plurality of seals. The packing head is configured to define a cooling flow path in flow communication with the rotor and configured to discharge a cooling steam flow toward the rotor. An anti-swirl device is coupled to the seal assembly and located between the rotor and the packing head.

Abstract: A locking blade for a rotor can include an airfoil portion with a root from which a tongue extends. Opposed bucket segments can engage the tongue and can be retained in a longitudinal direction of the blade by a fastener, such as a pin, that can extend through holes in the segments and tongue. Tines parallel to and on opposite sides of the tongue can extend from the root and include holes through which the fastener can extend, the bucket segments extending between respective tines and the tongue. The structure can eliminate an assembly gate in a rotor.
