Subsection 7.3.13 Feed Pump

The feed pump serves the same purpose here as it does in the simplified cycle; that is, it raises the pressure of the feedwater sufficiently to force it into the boiler to begin the cycle again.

The feed pump is usually a turbine driven centrifugal pump, and the discharge pressure is about 50 to 100 psi above the pressure in the steam drum.
