Water Heat Exchangers that use steam-driven turbines commonly use heat exchangers to boil water into steam. All fossil-fueled and nuclear power plants using steam-driven turbines have surface condensers to convert the exhaust steam from the turbines into condensate water for re-use.Water Heat Exchangers large power plants with steam-driven turbines, shell-and-tube surface condensers are used to condense the exhaust steam exiting the turbine into condensate water which is recycled back to be turned into steam in the steam generator.
