Abstract: A device and a method for using overcapacities in the power grid is provided. In case of an oversupply of energy, the energy is transferred to a thermal storage device directly via a heating element and in the discharge case of the thermal storage device the heat is removed from the thermal storage device and made available to a thermodynamic cycle whereby electrical energy is produced. The heat from the thermal storage device is used to preheat air in an air feed line to a combustion chamber, or fuel is pre-heated using heat from the thermal storage device.

Abstract: A gas turbine system includes a compressor; a combustion chamber; a gas turbine; and an evaporative cooler. The evaporative cooler includes a plurality of cooling elements, a flow channel, and a feed device. The plurality of cooling elements are arranged in the flow channel. The feed device supplies a liquid to the plurality of cooling elements. The liquid is evaporated or vaporized. Each of the plurality of cooling elements is a flat cooling sheet, a surface of the cooling sheet having hydrophilic properties at least in a subregion which is specified for forming a liquid film. The evaporative cooler is connected ahead of the compressor on an intake side.

Abstract: A device for increasing service life of a combustion installation is disclosed. The combustion installation has a gas-conducting component and a conducted gas has dirt particles. The gas-conducting component has a layer which is partially detached together with the dirt particles of the gas when the layer is impinged with the gas and when a dirt particle is deposited on the layer.

Abstract: An evaporative cooler for cooling a gas stream, in particular an air stream, including a number of cooling elements located in a flow channel, is provided. A liquid, preferably water, is supplied by a feed device and will be vaporized or evaporated. In one aspect, the surface of at least one of the cooling elements has hydrophilic properties, at least in one sub-region designed to form a liquid film.

Abstract: There is described a method for coating the surfaces of turbomachines that come into contact with fluid media, wherein the outer surface of parts of turbomachines that come into contact with fluid media are contacted by a coating comprising an inorganic-organic hybrid polymer. Furthermore, there is described a turbomachine, wherein the surfaces that come into contact with fluid media have an outer coating which comprises an inorganic-organic hybrid polymer. Such a turbomachine can be used for generating electric power.

Abstract: A superconductor structure is disclosed, comprising a composite body made of an electrically insulating substrate to which an intermediate layer is bonded, a buffer layer is deposited on the intermediate layer and a layer of a metal-oxide high Tc superconductor material is deposited on the buffer layer.
