A natural-draft cooling tower having a plurality of preferably roof-shaped heat exchange elements for condensing the turbine exhaust steam from a power plant. A portion of the heat exchange elements are connected to operate as condensers, and another portion of the heat exchange elements are connected to operate as dephlegmators, reflux condensers or fractionating columns, with the latter being disposed downstream, when viewed in the direction of flow of the steam, of the heat exchange elements that operate as condensers. In order to assure a complete condensation, and a residual condensation in the heat exchange elements that operate as reflux condensers, under all weather and load conditions, the heat exchange elements that operate as reflux condensers are each provided with a respective fan, the conveying capacity of which can be regulated.
In a natural-draft cooling tower having a plurality of preferably roof-shaped heat exchange elements substantially standing rather than lying as arranged for direct heat exchange and for condensing the turbine exhaust steam from a power plant, wherein a portion of said heat exchange elements are connected to operate as condensers, and additionally another portion of said heat exchange elements are connected to operate as reflux condensers, with the latter being disposed downstream, when viewed in the direction of flow of said steam, of said heat exchange elements that are connected to operate as condensers;
