another form of condensing system is the air-cooled condenser. the process is similar to that of a radiator and fan. exhaust heat from the low-pressure section of a steam turbine runs through the condensing tubes, the tubes are usually finned and ambient air is pushed through the fins with the help of a large fan. the steam condenses to water to be reused in the water-steam cycle. air-cooled condensers typically operate at a higher temperature than water-cooled versions. while saving water, the efficiency of the cycle is reduced (resulting in more carbon dioxide per megawatt-hour of electricity).
