WebFeed water heater can be either open or closed. In open feed water heater, there is direct mixing of feed water and steam while in closed feed water heaters are like counter flow … Webadding either open feedwater heaters and/or closed feedwater heaters, the efficiency of the cycle will increase [2]. This is due to the raise of the mean feedwater temperature at the boiler inlet which is heated by the extraction steam. The study has been done to determine[3] the effect of the number of closed feedwater heaters
WebThe high pressure feedwater heater is a counter flow, shell and tube heat exchanger that raises the temperature of the feedwater before entering the steam generator. By raising the feedwater temperature, the steam generator is more efficiently sized for its task of converting feedwater to steam and the plant operates at a higher efficiency.
