Abstract

The significant efficiency advantage of the Carnot cycle over the Rankine cycle is due to the fact that in the Carnot cycle all external heat addition is at a single high temperature and all external heat rejection at a single low temperature. The Rankine-cycle thermal efficiency could be improved by increasing the average water temperature at which heat is received. This could be accomplished by an internal transfer of heat from higher-temperature steam to lowtemperature feed water. An internal transfer of heat that reduces or eliminates low-temperature additions of external heat to the working fluid is known as regeneration. Regeneration is accomplished in all large-scale, modern power plants through the use of feed water heaters. A Feed Water Heater (FWH) is a heat exchanger in which the latent heat (and sometimes superheat) of small amounts of steam is used to increase the temperature of liquid water (feed water) flowing to the steam generator. There are two types of feed water heaters, (i) Open Feed water heaters and (ii) Closed Feed water heaters
