Abstract
Since over 40 years, large natural draft cooling towers dominate thermal power stations in Europe. With actual heights up to 200 m, they balance thermal plant efficiencies closely to 50% with environmentally soft releases of residual process-heat. Between 1965 and 1984, a series of cooling tower collapses hit the international power technology, from which Germany remained unaffected. But some of the German towers demonstrate, after 35 and more years of service life, severe aging effects due to survived storms and service conditions. The article describes, after preliminary remarks on design characteristics of natural draft cooling towers, typical damage phenomena which may affect structural safety as well as residual service life. Then the paper turns to computer simulations of degrading towers to determine reductions of safety and residual life, modeling aging effects of gales and service deterioration.
