  • Steam turbine with single shell casing, drum rotor, and individual nozzle rings
    Patent number: 8926273
    Abstract: A steam turbine with a drum rotor utilizing individual nozzle ring assemblies in the IP section incased by a single shell. In one embodiment, a steam turbine has a high pressure (HP) section with a double shell drum and an intermediate pressure (IP) section with a single shell drum, with the IP section including a plurality of individual nozzle ring assemblies axially spaced along the single shell casing, such that each nozzle ring assembly surrounds the drum rotor. In other embodiments, a low pressure section (LP) of the steam turbine can have a single-flow or dual-flow connection to a condenser, and the condenser can be positioned to the side, vertically below, or axially aligned with the LP section.

  • Methods and systems for calculating steam turbine radial clearance
    Patent number: 6868363
    Abstract: A method and a system for determining radial clearances in a rotating machine are provided. The rotating machine includes at least one shell, at least one rotor, and at least one stationary component. The method includes creating a finite element model for at least one component within the rotating machine, creating a cycle deck data file for the rotating machine, determining an initial clearance versus time, and determining an initial clearance versus location.
