Feedwater Heaters are classified as low and high pressure heaters with one heater. This item is installed to improve power generator efficiency by heating supplied water and reducing breakage due to heat stress from temperature differences in boiler tubes. -heating areas, this item requires thoughtful engineering and production. To meet client's need of the most efficient of electric power generation cycle, special and innovative design feature have been introduced Energyen's Feedwater Heaters. The physical and thermal characteristics are vastly different between high and low pressure Feedwater Heaters.
