STEAM TURBINE AND METHODS OF ASSEMBLING THE SAME

摘要

A steam turbine is provided. The steam turbine includes a housing and a steam inlet coupled in flow communication to the housing which is configured to discharge a first steam flow within the housing. A stator is coupled to the housing and includes plurality of vanes. A rotor is coupled to the housing and located within the stator, wherein the rotor and the stator are configured to form a first flow path there between 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 define a second flow path in flow communication with the first flow path and to discharge a second steam flow within the at least one root. The at least one root of the plurality of blades includes an angel wing in flow communication with the passageway and configured to seal the passageway from the first flow path.
