Some U.S. electricity generating plants use dry cooling

----- 7) - Heat input to the steam cycle (2.8) '£ ~ Heat input to the boiler 2.2.2.2 Waste Heat Rejection Rate— The heat rejection rate of a power plant to its condenser cooling system can be calculated by the following equation, given the cycle heat rate and net cycle power output: Qrej = (HR - 3413) x P x 1000 (2.9) where: Qrej = heat rejection rate to the condenser cooling system, Btu/hr. HR = cycle heat rate, …

May 29, 2020 · Cooling systems are often the largest source of water use in power plants because of the large amount of heat that must be removed to condense the steam used to drive turbine generators. Historically, this cooling was provided by water sources such as rivers and lakes, but the number of power plants using dry cooling—a cooling system that uses little to no water—has increased in recent …

WASTE HEAT TO POWER SYSTEMS - EPA

Cooling towers with recirculating water reduce the overall efficiency of a power plant by 2-5% compared with once-through use of water from sea, lake or large stream, the amount depending on local conditions. A 2009 US DOE study says they are about 40% more expensive than a direct, once-through cooling system.
