FEEDWATER HEATERS

A feedwater heater is used in a conventional power plant to preheat boiler feed water. The source of heat is steam bled from the turbines, and the objective is to improve the thermodynamic efficiency of the cycle. The most common configuration of feedwater heater is a shell and tube heat exchanger with the feedwater flowing inside the tubes and
