Abstract: For a new power plant, incorporating an ACC in the plant’s design in lieu of a water cooled surface condenser is in most cases quite feasible technically but usually commercially non- competitive. In an operating plant on the other hand, because of the reasons mentioned above, installing an ACC is an extremely disruptive and usually cost-prohibitive undertaking. The alternative configuration described below, seeks to overcome the ACC’s shortcomings, making the switch to air cooling feasible for most operating plants and serving as a credible alternative to the cooling tower or ACC options for new power plants.
