Abstract :
As growing interest is shown in inairect ary cooling plants for power stations, experiences gained in such plants having been in operation for 6-17 years are summarized. Solely a few important questions are dealt with, such as materials and corrosion of heat exchangers, mechanical and natural draft, wind effect and cooler arrangement, direct contact and surface condensers. This paper should contribute to clarify some up-to- date important problems in this field, discussed in technical literature.
