  • 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.
