  • Patent number: 8961130
    Abstract: A system and method to cool the air inside the nacelle and the heat generating components, particularly of an offshore wind turbine is presented. The ambient air first enters an air handling unit near the tower bottom where the airborne water droplets and salt particles are removed. The clean air is then compressed adiabatically, thus increasing the dew point temperature of the water vapor in the air. The high pressure, high temperature air from the compressor is then cooled and dehumidified in a sea water-to-air heater exchanger or an air-to-air heat exchanger. The high pressure air from the heat exchanger then enters the turbine at the tower bottom and flows up to the nacelle where it is allowed to expand adiabatically in a duct. The duct helps direct the resulting cold air over the heat generating components. The cold air can also used to cool these components internally. The warm air ultimately exits the nacelle at the rear top.

  • Publication number: 20140161597
    Abstract: The present application relates to a splitter nose of an axial turbomachine designed to separate an annular flow into the turbomachine into a primary flow and a secondary flow for undergoing a thermodynamic cycle. The nose includes a de-icing device with a wall defining, at least partially, an annular channel. A hot oil stream created by the turbomachine circulates in this latter. The oil runs through the circular nose and de-ices it while itself getting cooled. The wall is located so as to form the leading edge of the said splitter nose. The wall is an open or closed strip such as a tube which can be fixed by bonding, welding or recessing. The present application also relates to a multi-flow turbomachine with splitter noses fitted with de-icing devices.

  • Publication number: 20140150449
    Abstract: A gas turbine engine including a compressor rotor and a turbine rotor connected by a compressor shaft portion connected to the compressor rotor and a turbine shaft portion connected to the turbine rotor. The compressor shaft portion and the turbine shaft portion are connected axially together by a shaft coupling, between the compressor rotor and the turbine rotor, and at least a bearing rotatably coupled to the compressor shaft portion adjacent the shaft coupling. The compressor shaft and/or the turbine shaft are provided with openings permitting cooling air to enter air passages in the area of the shaft coupling and surrounding the end of the turbine shaft portion, in order to dissipate heat originating at the turbine rotor and thus reducing the thermal stresses at the bearing.

  • Patent number: 8740549
    Abstract: A lubrication system for turbocharger(s) ensures continuous lubrication of bearings and shaft of the turbocharger with lubricant retention during start and shut down of turbocharger-associated systems thereby enhancing the performance and turbocharger life. A shaft and bearings are lubricated by introducing pressurized lubricating oil through an oil inlet passage in the bearing housing and after lubricating, the lubricant returns to the engine oil sump located below the turbocharger through the oil outlet passage. A valve in the oil inlet pipe line permits lubricant flow to the bearings during engine running, and when the engine stops and oil pressure falls below the valve opening pressure, the valve shuts and traps the lubricant in oil inlet pipe that is above the valve. The oil outlet pipe retains sufficient lubricant in the bearing housing which lubricates the shaft and bearings post engine shutdown.

  • Patent number: 8727704
    Abstract: A ring segment for a gas turbine engine includes a panel and a cooling system. The cooling system receives cooling fluid from an outer side of the panel for cooling the panel and includes at least one cooling fluid supply passage, at least one serpentine cooling passage, and at least one cooling fluid discharge passage. The cooling fluid supply passage(s) receive the cooling fluid from the outer side of the panel and deliver the cooling fluid to a first cooling fluid chamber within the panel. The serpentine cooling passage(s) receive the cooling fluid from the first cooling fluid chamber, wherein the cooling fluid provides convective cooling to the panel as it passes through the serpentine cooling passage(s). The cooling fluid discharge passage(s) discharge the cooling fluid from the cooling system.

  • Publication number: 20140123647
    Abstract: A stack ring is formed by an outer ring and an inner ring and is inserted in an annular gap formed between an inlet sleeve and an inner casing. The outer periphery of the outer ring and the inner periphery of the inner ring each have a land part having a flat face and taper faces formed on upper and lower sides of the land part. A ratio of L1 to L0 is 0.3 to 0.7 where L1 is a length of the land part and L0 is a total length in the up-down direction. A ratio of S to S0 is not less than 0.95 where S is an area of the cross sectional shape of the outer ring or the inner ring and S0 is an area of a virtual rectangle BCDE and the taper faces have an inclined angle of 1° to 10°.

  • Patent number: 8714910
    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.

  • Patent number: 8678750
    Abstract: A specialty pump and heat exchange system having a fluid pump driven by a gear assembly. The fluid pump has a pump casing and an inboard head that form a fluid passageway when connected together. The gear assembly uses lubricant in the transmission and that lubricant is cooled by being pumped from the gear assembly through a lubricant passageway in the inboard head and then recycled back to the gear assembly for further use. In addition to cooling the lubricant, the system warms the fluid pump and/or fluid passing through the fluid pump.
