New German Natural Draft Cooling Towers for High-Efficient Power Generation
Presently in the West of Germany, several thermal power plants are renewed to improve their efficiency. These new power stations are fuelled either by hard coal or by lignite; the maximum net electric capacity per power block is up to 1.100 MW. Also since the re-unification 1990, Germany had to renew a series of thermal power stations in its East, mainly fuelled by lignite. All plants are equipped with high-rise (wet) natural draft cooling towers (NDCT) up to heights of 200 m, mainly for environmental and for economical reasons. With these NDCTs, the net electric degree of efficiency of an entire power block lies closely below 45%. Forerunners of such high-efficient NDCTs serve at French, German and Swiss nuclear power plants. Consequently, Germany presently is the only nation worldwide with continuing design and construction experiences in NDCT-technology in the last 20 years. Many of these NDCTs are structurally designed by Kraetzig & Partners Consultant Engineers, Bochum, others verified by Kraetzig & Partners' State Authorized Checking Engineers (Prüfingenieure). All authors of the present contribution are cooling tower experts associated with Kraetzig & Partners, two of them CE professors at German Universities. Figure 1 introduces the reader to our world-largest lignite power block at the RWE Power Station Niederaussem, equipped with the world-highest NDCT of 200 m of total height.
