STEAM TURBINE WITH SUPERHEATED BLADE DISC CAVITIES

摘要

Several means for providing superheated steam varying in pressure and temperature in a plurality of cavities serially disposed between blade discs of a steam turbine in which steam flows from a high pressure to a low pressure portion and improved seals disposed at the radially outer periphery of the cavities which cooperate with the means for providing superheated steam in the cavities to eliminate moisture in the cavities and eliminate stress corrosion in the blade discs.
