Two Rankine cycle's are proposed: (a) Steam at 60 bars and 540°C is expanded to 5 bars, where a portion is bled to an open feedwater heater. The remaining portion is reheated to 500°C and then expanded to 0.08 bar. (b) Steam at 60 bars and 440°C is expanded to 10 bars, where a portion is bled to an open feedwater heater. The remaining portion is reheated to 440°C and then expanded to 0.08 bar. Compare their thermal efficiency.
