Patent number: 9574453Abstract: 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.Type: GrantFiled: January 2, 2014Date of Patent: February 21, 2017Assignee: General Electric CompanyInventors: Xiaoqing Zheng, Thomas Joseph Farineau, Sacheverel Quentin Eldrid, Jason L.

Patent number: 6382903Abstract: In a turbine having closed-circuit steam-cooling passages about the rim of the rotor during steady-state operation, compressor discharge air is supplied to the rotor bore for passage radially outwardly into the wheel space cavities between the wheels and spacers. Communicating slots and channels in the spacers and wheels at circumferentially spaced positions enable egress of the compressor discharge air into the hot gas flow path. At turbine startup, cooling air flows through the closed-circuit steam passages to cool the outer rim of the rotor while compressor discharge air pre-warms the wheels and spacers. At steady-state, cooling steam is supplied in the closed-circuit steam-cooling passages and compressor discharge air is supplied through the bore and into the wheel space cavities to cool the rotor.Type: GrantFiled: December 22, 2000Date of Patent: May 7, 2002Assignee: General Electric CompanyInventors: Philip M. Caruso, Sacheverel Quentin Eldrid, Azad A. Ladhani, Alan Richard DeMania, Gene David Palmer, Ian David Wilson, Lisa Shirley Rathbun, Robert Craig Akin
