In either case, the effect of a feedwater heater, open or closed, is to improve the efficiency of a Rankine Power Cycle by reducing the irreversibility of the heat transfer that takes place in ... WebFeedwater heaters can also be "open" or "closed" heat exchangers. An open heat exchanger is one in which extracted steam is allowed to mix with the feedwater. This kind of heater will normally require a feed pump at both the feed inlet and outlet since the pressure in the heater is between the boiler pressure and the condenser pressure.
