WebThe figure, taken from Moran and Shapiro Example 8.5, shows the components in a Rankine power cycle with regeneration as well as the corresponding T-s diagram. For this problem, focus on the device labeled "open feedwater heater." An open feedwater heater is a fancy name for a mixing chamber.
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. sightseeing tours honolulu hiWebIn open feed water heater, pump release (1-m 1) kg feed water at point 2 which is mixed with m 1 kg of extracted or bled steam at point 6.
