  • Patent number: 5779435
    Abstract: The object of the invention is to increase the efficiency of a low-pressure steam turbine connected to a condenser and to reduce its cost of manufacture.According to the invention this is achieved when the dividing plane (8) of the top and bottom part (6, 7) of the outer casing (1) of the low-pressure steam turbine lies at the level of the axis (9) of the turbine rotor (4) and the concrete foundation (14) reaches up to the dividing plane (8). Both the bottom part (7) of the outer casing (1) and the bearing points (10) of the turbine rotor (4) are secured in the concrete foundation (14). The outer casing (1) is designed to be open at least on one side at right angles to and horizontally to the axis (9) of the turbine rotor (4). A condenser (16) is attached to each lateral opening (17) in the outer casing (1).

  • Patent number: 5695317
    Abstract: In a steam turbine, which essentially comprises a bladed rotor (2), an outer casing (4), at least one inner casing (3), a live-steam line (8) for inflowing steam (13), a valve (22) for setting the quantity of inflowing steam (13), and an exhaust-steam line (19) for the outflowing steam (17), the valve (22) is arranged in a connection piece (4a) of the outer casing (4). The part of the valve housing (10) to which the inflowing steam (13) is admitted is surrounded with steam, which fills the space (18) between inner casing (3) and outer casing (4).
