Condenser (Heat Transfer)

A condenser is a heat exchanger that cools a gaseous substance until it condenses into a liquid, transferring heat from the working fluid to a secondary fluid or to the surrounding air. Because a vapor releases large quantities of latent heat as it condenses, this phase change transfers substantially more thermal energy than simple temperature based cooling. In thermal power stations, a surface condenser is typically installed at the outlet of each steam turbine as a shell and tube heat exchanger, with cooling water flowing through the tubes while steam condenses on the tube exterior and collects in a hotwell. This arrangement lets a power plant reject waste heat efficiently and recover condensate for reuse, making the condenser essential to a power station's overall efficiency and continuous operation.
