The laws of nature dictate that over 60 percent of the thermal energy produced by a steam power plant must be rejected to the environment. The local source of natural water is the usual recipient of this “waste” heat. The rejection of the plant’s waste heat to the air, in lieu of water, has thus far been challenging because of the large land area and capital cost associated with conventional air cooled condensers (ACCs) – until now. Holtec’s R&D team proudly announces the successful development of a whole new genré of ACCs that require less than half of the land area of a conventional “A- frame” ACC (see illustration) presently sold by Holtec and other world suppliers. In contrast to the conventional ACCs made of carbon steel tubes with brazed aluminum fins, the new ACC features stainless steel tubes resulting in significantly reduced flow accelerated corrosion and iron transport problems that currently plague the ACC industry. The conventional A-frame ACC, shown below with HI- VACC for identical heat duty, illustrates the reduction in the system footprint area achieved by the latter.
