In the western US, wetrecirculating systems are predominant. Drycooling systems use air instead of water to cool the steam exiting a turbine. Drycooled systems use no water and can decrease total power plant water consumption by more than 90 percent. [2] The tradeoffs to these water savings are higher costs and lower efficiencies.

Abstract The share of coal generation in the global electricity production remains stable and prevails over other primary energy sources. A decrease in the coalfired power generation in some EU countries and the United States is balanced by its stable growth in Asia (China, India, Indonesia, South Korea) and Africa (South Africa). In 2021, global coal generation increased by 9% to a new all ...

Wet cooling towers (WCT) are widely used to reject the unutilized heat in coal thermal power plants (TPPs). But this comes at the cost of excessive water consumption. Adoption of aircooled condensers (ACC), also known as dry cooling systems, in all proposed Indian TPPs would reduce their water consumption by 26% in 2030. However, power producers are reluctant to install ACC due to technical ...
