    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 steam turbine is provided. The steam turbine includes a housing, a first steam inlet configured to discharge a first steam flow within the housing, and a second steam inlet configured to provide a second steam flow. A rotor and stator are coupled to the housing and configured to form a first flow path therebetween and in flow communication with the first steam flow. The rotor includes a plurality of blades coupled to the rotor, at least one root of the plurality of blades has a first side, a second side and a passageway coupled in flow communication to the first side and the second side. The passageway is configured to receive the second steam flow within the at least one root. The at least one root includes an angel wing configured to seal the second steam flow from the first flow path.
