This paper gives a brief synopsis of the thermo-dynamic imperative of the feedwater heater in the power cycle, followed by the development of two performance parameters. These two parameters, the “Flash Protection Index” (FPI) and the “Heater Time Constant,” are closely linked to the heater thermal/hydraulic performance, and can be used to avert operational problems by identifying them at the design stage. Finally, a method to size the vapor suppression plate for feedwater heaters is also presented.
