  • Reheat Rankine Cycle - GeeksGod

    Apr 11, 2020 · Rankine cycle efficiency can be improved by using the Reheat cycle. In the Reheat cycle, the steam is extracted at a point when it becomes just wet, from the turbine, and is reheated with the help of flue gases from the boiler furnace. The main objective of Reheating is to increase the "Dryness Fraction" of the steam passing through the Learn More

  • Ideal Rankine Cycle

    Increasing the Boiler pressure:- Increasing the operating pressure of the boiler, automatically raises the temperature at which boiling takes place. This raises the average temperature at which heat is added to the steam and thus raises the thermal efficiency of the cycle.. Reheat Rankine CycleLearn More

  • (Get Answer) - Steam leaves the boiler of a Rankine cycle

    Sep 14, 2021 · Steam leaves the boiler of a Rankine cycle at 150 kg/min, 600°C, and 4 MPa and expands in a high-pressure turbine to 1 MPa. Part of the steam is used in an open heater, while the remainder is returned to the boiler where it is superheated back to 600°C, and then expands in a low-pressure turbine.Learn More

  • 4.5 Steam Turbines and Rankine Bottoming Cycle

    4.5.2.1 Basic Process and Components. The thermodynamic cycle for the steam turbine is the Rankine cycle. The cycle is the basis for conventional power generating stations and consists of a heat source (boiler) that converts water to high pressure steam.Learn More

  • rankine-cycle - LearnChemE

    Rankine Cycle. In a Rankine cycle, high-pressure liquid water (1) enters a boiler where it is heated to saturation temperature (2), vaporized, and superheated (3). The superheated steam is fed to a turbine, where it expands and generates mechanical work. The steam exits the turbine at a lower pressure and temperature as either superheated steam Learn More

    Allow the boiler pressure to rise to approximately 700 kPa. While maintaining 700 kPa of boiler pressure, the steam admission valve should be opened slowly. The rate at which steam admission valve is opened should be just enough to maintain 700 kPa of boiler pressure and to counter any tendency for the boiler pressure to increase beyond this value.Learn More
