  2. Components of a Vapor Power Plant

  3. Rankine Cycle Pump: Turbine: Overall Performance: Condenser (1 side): Boiler:

  4. Rankine Idealizations Processes 1-2, 3-4: Isentropic Processes 2-3, 4-1: Isobaric Saturated liquid at State 3 Reversible Pump Work Equation: For Incompressible Fluids Only!

  5. Principal Device Analysis:

  6. Principal Device Analysis:

  7. Cycle Performance Parameters

  8. Improving Cycle Performance One key is in the pressures: Each method increases cycle thermal efficiency!

  9. Improving Cycle Performance Superheat and Reheat protect the turbine, and increase TH.

  10. Improving Cycle Performance Adding an Open Feedwater Heater (with pump).

  11. Improving Cycle Performance Adding a Closed Feedwater Heater.
