    Abstract: A system for removing moisture from a steam/water mixture engaging a stationary component of a steam turbine. The system includes an airfoil located within a flow path of a steam turbine. The airfoil is configured for removing moisture from a steam/water mixture traveling in the flow path. To this end, the airfoil includes a cavity in flow communication with the steam path through at least one inlet and outlet opening, near the leading and trailing edge of the airfoil, respectively. Moisture and steam are extracted from the surface through the inlet openings, the steam and water are separated in the cavity, the separated water flows towards the bottom end, and the dry steam flows through the outlet opening and returns to the steam path. The dry steam blowing out of the trailing edge reduces the size of secondary droplets, and thereby prevents erosion.

The apparatus further comprises a chamber closure (48) mounted about said core member (28), said closure being resiliently deformable between an at rest state in which the closure contacts the chamber wall (44) and an actuated state in which the closure is spaced there-from, wherein the chamber has an aperture (32;35;55) for receiving liquid phase fluid from the interior of said rotating body. Upon build up of sufficient liquid in said chamber (30) the closure (48) moves to said actuated state so as to release liquid from the interior of the body.

  • Patent number: 7921646
    Abstract: A turbocharger is disclosed that includes a compressor, a turbine connected to the compressor by a mechanical shaft, and a fluidic drain valve in flow communication with an air bleed port of the compressor and an exhaust plenum to drain water accumulated inside the turbocharger such that water accumulated in the exhaust plenum is drained during shutdown when no air from the bleed port flows through the fluidic drain valve.

  • Publication number: 20100290896
    Abstract: The invention relates to a compressor unit, in particular, for submarine application, comprising an electric motor. The transported medium for compression, in particular, natural gas for transport, not only frequently contains various aggressive chemical compounds but is also carrier of various condensates which hinder compression and in particular lead to increased wear of the compressor. On assembly aggressive sea water can also enter the compressor unit. The invention provides a solution to the above, wherein the rotation axis is arranged vertically during operation and the housing comprises a drain at the lower axial end. The invention further relates to an assembly method for a compressor unit, in which the compressor unit is filed above water with an incompressible fluid, transported to a submarine operating position, connectors are connected to the inlet and the outlet and the fluid removed from the compressor unit through the drain.

  • Publication number: 20100221095
    Abstract: A steam turbine is disclosed which includes a casing containing a plurality of expansion stages, each including stator and rotor airfoils. Downstream of the stator airfoils of one or more expansion stages, the casing includes a slot arranged to receive moisture that concentrates on an end wall of the stator airfoils and discharge it to the outside. Each end wall has a side portion facing the slot having a variable radial obstruction in a tangential direction, in order to define with the slot a passage through which the moisture may pass that is smaller or closed at the suction side and larger at the pressure side of the stator blades, to at least partially prevent the dry steam from entering the slot at the suction side of the blade.

  • Patent number: 7785069
    Abstract: The ventilation unit has an electric motor, the output shaft of which is fitted with a fan having a cup-shaped central body and a number of blades. The central body is defined by a base wall, and by an annular wall from whose outer face the blades extend. And the main characteristic of the present inventive subject matter lies in through windows being formed in the annular wall of the central body to channel out, in use, any condensate formed inside the central body.

  • Patent number: 7731480
    Abstract: A power turbine is provided in the form of a set of plates that cooperate to form a housing, with a set of spaced apart disks mounted on a shaft within the housing. Some of the plates and disks cooperate to allow gas or steam to be injected to provide a driving force on the shaft, while others of the disks and plates cooperate to form one or more integral pumps. The pumps are used to pull cooling liquid or water into the housing, and to cool the driving disks. In this way, the steam that drives the disks is condensed while still in the housing, with a water level maintained on the driving disks. In operation, the steam directly acts on the disks toward the outer circumference of the disks, but more toward the center of the disk, the steam transfers its energy to the water, and the water transfers the energy to the disk.

  • Patent number: 7704040
    Abstract: A water pump includes an impeller provided on an end of a rotational shaft supported on a body through a bearing, a mechanical seal provided between the impeller and the bearing, a draining hole guiding a coolant leaked from the impeller side to a reservoir provided at a bottom of the body via the mechanical seal, a vapor outlet provided above the reservoir for establishing communication between the reservoir and the atmosphere, and the draining hole opening to the reservoir at a lower level than the vapor outlet. An axis of the reservoir is offset from a vertical plane which passes through an axis of the rotational shaft.

  • Patent number: 7462013
    Abstract: The discharge water means (1m) is provided within an area equal to or more than an area of the shroud extending to 20 degree points in both directions from a center that is a lowest portion of the ring portion (1h). Due to this, if water drops adhered to the surface of the blade wheel (1a) and the shroud (1c) are collected at the lower side thereof due to gravity, it is possible to readily discharge the water. As a result, as it is possible to prevent the water drops from being stored in a clearance between the blade wheel (1a) and the shroud (1c), even when the temperature of the atmosphere is low in a winter season or the like, it is possible to prevent a freezing lock phenomenon from occurring.
