Two classifications of heat exchangers are associated with the steam cycle. These are the condenser located at the exhaust of the steam turbine, and feedwater heaters located in the condensateboiler feedwater cycle that utilize extracted steam from the steam turbine. There are many other heat exchangers in the power plant, even some associated with the steam turbine or condensate cycle, but only the condenser and feedwater heaters are considered steam cycle heat exchangers and discussed in this chapter.
