  • Steam turbine
    Patent number: 8454306
    Abstract: A steam turbine (10), especially for the high-pressure range or intermediate-pressure range, includes a rotor (11) which is rotatably mounted around an axis and concentrically enclosed at a distance by an inner casing (12), wherein between the rotor (11) and the inner casing (12) a flow passage (13) is formed, which on the inlet side is axially delimited by a balance piston (18) which is arranged on the rotor (11), and into which flow passage rotor blades (15) and stator blades (17), alternating in the direction of flow, radially project, and wherein, at the entry of the flow passage (13), an inlet scroll (14), through which steam is guided from the outside radially inwards and deflected in a deflection region (27) in the axial direction to the inlet of the flow passage (13), is formed on the inner casing (12).
