  • 7.6. Rankine cycle | EME 812: Utility Solar Power and

    Increasing the boiler pressure results in higher average steam temperature in the boiler. This effect allows additional work to be done in phase 2-3 (Fig. 10.3c). However, there is some loss of useful work in phase 3-4 because of necessity to re-heat the steam. Reheating is used to mitigate higher moisture content of the high-pressure steam.Learn More
