A steam turbine is provided in the present invention. The steam turbine includes a housing and a steam inlet configured to discharge a flow of primary steam 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 therebetween, and in flow communication with the flow of primary steam. 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 towards the rotor. An anti-swirl device is coupled to the seal assembly and located between the rotor and the packing head. |
