Surface Condenser

A surface condenser is a commonly used term for a water-
cooled shell and tube heat exchanger installed on the
exhaust steam from a steam turbine in thermal power
stations. These condensers are heat exchangers which
convert steam from its gaseous to its liquid state at a
pressure below atmospheric pressure. Where cooling water
is in short supply, an air-cooled condenser is often used. An
air-cooled condenser is significantly more expensive and
cannot achieve as low a steam turbine exhaust pressure as
a water-cooled surface condenser.
