Abstract:
A seal for sealing a seal groove in a shroud of a turbine vane. The seal may include a cooling system configured to pass cooling fluids through a cooling fluid supply port in a shroud, through a cooling system in which the cooling fluids contact the shroud and the seal, and exhaust the fluids through a gap between adjacent turbine vanes. The seal may include an elongated cooling channel for channeling cooling fluids from a supply to an exhaust channel at a first end. The cooling system may remove heat from the turbine vane shroud, the seal, and other related components, thereby reducing the likelihood of premature failure.
Abstract:
A turbine blade which can be subjected to a hot gas flow includes a substrate, at least one interior space and a plurality of bores leading from the interior space out of the substrate. The substrate is at least partly covered by a heat-insulating-layer system at a suction side and/or a pressure side. At least one of the bores is closed by the heat-insulating-layer system and at least one further bore is open for developing film cooling.

Abstract:
An electrical power system includes a power grid and a plurality of power plants connected to the power grid. A central repository including one or more electrical energy storage devices is connected directly to the power grid. The one or more energy storage devices are configured to be connected to the power plants via the power grid. The central repository is operable to draw a portion of a power output produced by one or more of the power plants via the power grid during a first period, for storage therein. The central repository is operable to discharge power to the power grid during a second period shifted in time from the first period. The discharged power is a function of a grid requirement or a function of a power demand notified by an individual power plant of the electrical system.
Abstract:
The turbine blade has an internal space through which a coolant fluid is guided and in which stiffening ribs are formed to reinforce and support the external walls. Coolant screens that reduce the cooling of the stiffening ribs, are arranged in front of the stiffening ribs in order to reduce thermal stresses. The turbine blade is preferably a gas turbine blade.
Abstract:
The invention relates to a turbomachine, in particular to a gas turbine and to a method for accelerating a temperature modification of a rotor shaft rotationally mounted in said turbomachine. The aim of said invention is to develop a device and a method for the turbomachine making it possible to reduce the size of a radial split of the turbomachine in order to obtain greater degree of efficiency. The inventive turbomachine comprises a rotor rotationally mounted in the case of the turbomachine, a feeding channel embodied in the rotor for introducing a fluid and an outlet channel embodied in the rotor for removing said fluid. An inlet orifice of the feeding channel is disposed further inside than the outlet orifice of the outlet channel, and means influencing a liquid flow is formed of an actuating device dependent on centrifugal force. Methods for cooling the rotor only by decelerating the gas turbine and for heating the turbomachine rotor by heating fluid flowing therethrough are also disclosed.
Abstract:
A component can be subjected to hot gas. At least one duct is provided which can be subjected to a cooling fluid. The duct is bounded by two first walls opposite to one another. The walls include turbulators with the same direction of inclination. In order to avoid constrictions, the turbulators of the first wall have a different angle of inclination relative to a flow direction of the cooling fluid to the turbulators of the second wall.
Abstract:
A method is for producing a turbine blade, in particular, a gas turbine blade, comprising a head, a foot, and a blade section, in addition to an internal canalization system, including individual channels through which coolant gas can pass along a flow path within the turbine blade. The turbine blade also includes a throttle device which influences the passage of the coolant gas without impairing the flow of the coolant gas in the intake area. The throttle device is located in the rear section of the flow path, and is positioned upstream of the exit openings.
Abstract:
A covering element is for the protection of components in a machine subjected to high thermal load, in particular of components in a gas turbine. The covering element includes a wall with a hot side capable of being exposed to a hot medium, and with a cool side located opposite the hot side. The cooling side includes a cooling surface capable of being acted upon by a coolant. Holding elements are provided on the cool side.
