Problems on reheat rankine cycle
WebbWater is the working fluid in an ideal Rankine cycle with reheat. The steam at the high-pressure turbine inlet is at 1500 psia and 800 o F and the effluent is saturated vapor. The … WebbRankine cycle, such as Reheat cycle, Regenerative cycle, etc. With re-heat, there is a possibility of an increase in thermal efficiency that re-sults in higher boiler pressure and yet avoids low dryness fraction of steam at the turbine exhaust [27]. The regenerative cycle has an ad-vantage of increasing the feedwater temperature on its way back ...

WebbComparing these two cycles we observe that all the processes except water heating 1–1′ are reversible processes. Rankine cycle efficiency is less than Carnot efficiency because of only one irreversible process 1–1′. If we could eliminate this irreversibility, we can get the Rankine cycle efficiency same as that of Carnot efficiency. our office addressWebbThe heat added by heating and reheating in the boiler during the constant gth {gth,non-reheat d1 ~ (6) pressure processes 2–3 and 4–5 is gth,non-reheat (h3 {h2 )z(h5 {h4 ) qin … our of fatimaWebbRankine cycles reheat and superheat the low-pressure stage.
