Beschreibung
Zusammenfassung:	A steam turbine with a drum rotor (250) utilizing individual nozzle ring assemblies in the IP section (220) incased by a single shell. In one embodiment, a steam turbine (200) has a high pressure (HP) section (210) with a double shell casing and an intermediate pressure (IP) section (220) with a single shell casing, with the IP section (220) 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 (250). In other embodiments, a low pressure section (LP) (240) of the steam turbine (200) can have a single-flow or dual-flow connection to a condenser (260), and the condenser (260) can be positioned to the side, vertically below, or axially aligned with the LP section (240).
