摘要
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.
