FUNDAMENTALS OF ENGINEERING THERMODYNAMICS
To overcome this shortcoming, we look for ways to raise the temperature of the
liquid leaving the pump (feedwater), before it enters the boiler. One way to
accomplish this is to compress the feedwater isentropically to a high temperature,
as in ...

The Fundamentals of Nuclear Power Generation: Questions and ...
The use of feedwater heaters in the plant cycle allows the efficiency of the unit to
be increased by using extraction steam from the turbine to be feed into these
heaters to preheat the condensate/feedwater heading toward the boiler. If
