Abstract: A cooling tower has a flue gas outlet extending upwardly above the heat exchanger baffles in which the water from a steam power plant is cooled in counterflow to a rising cooling air stream. The mouth of the duct is formed with a droplet trap supplied with rinse water and cooperates with a collector for the rinse water which is led out of the tower independently of the cooled water of the heat exchanger zone.

Abstract: The present invention relates to a cooling tower for the cooling water that drains from the condensor of a steam generator or from the condensors of a plurality of steam generators; the tower is fitted with large-area inserts and these form a heat-exchange area into which the cooling water is passed; a rising flow of air passes through this zone in counterflow to the cooling water, the cooling tower being provided with a smoke-gas feed to introduce cleaned, preferably wet-cleaned, smoke gas into the flow of cooling air, which is connected to a plurality of gas outlet pipes, the outlet cross-sections of which open out into the cooling tower above the heat-exchange zone. In order to improve the introduction of the cleaned smoke gases into the flow of cooling air within a cooing tower, the present invention proposes that rotors be provided in the gas outlet pipes in the area of their outlet cross-sections.

Abstract: A part of a solid fuel is combusted in a fluidized bed combustor; a remainder of the fuel is combusted in a dust combustor. Waste gases from the fluidized bed are fed to the dust combustor. A heat exchanger in the fluidized bed heats compressed air in which fuel is combusted to drive a hot gas turbine. A heat exchange in the dust combustor heats water to superheated steam to drive a steam turbine.

Abstract: Solids are removed from solids-containing undistillable or difficultly distillable liquid hydrocarbon fractions by cooling, solidifying and pulverizing the solids-containing fractions, by contacting the pulverized material with solvent and by separating the solids, then the solvent, resulting in relatively solids-free hydrocarbon fractions.
