  • Publication number: 20140060058
    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.

  • Patent number: 8641019
    Abstract: A diversion station is provided. The diversion station makes it possible to particularly effectively cool diverted water vapor by mixing it with water. The diversion station includes a mixing device, which comprises a so-called static mixer that is substantially made of a wire mesh. The wire mesh is produced by at least one wire that is substantially interlaced into loops. In the intended installation situation, the mixer is installed upstream of a water injection with regard to a flow direction specified by the water vapor such that the mixture of water and water vapor flows through the loops.

  • Publication number: 20100129645
    Abstract: A method for producing a hydrophobic coating for condensers to obtain a dropwise condensation, a hydrophobic coating for condensers, a hydrophobically-coated condenser, and a coating agent are provided. A coating agent is applied to a condenser. The coating agent includes a liquid solvent and a coating material. The coating material may be applied by a wet-chemical method.

  • Publication number: 20100101234
    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.
