  1. Rankine Cycle for Power Generation By P M V Subbarao Mechanical Engineering Department I I T Delhi An appropriate amalgamation of Theory and Practice !!!!

  2. Ideal Rankine Cyclic Model for Power Generation System

  3. Constant Pressure Steam Generation

  4. Constant Pressure Steam Generation Process Theory of flowing Steam Generation Constant Pressure Steam Generation: =0

  5. Knowledge for Energy Audit Constant Pressure Steam Generation: Practical way of understanding the use of fuel energy: Is it possible to get high temperature with same amount of burnt fuel? What decides the maximum possible increase for same amount of burnt fuel?

  6. The Law of Learning one fourth from the teacher, one fourth from own intelligence,one fourth from classmates, and one fourth only with time. Mahabharath

  7. Carnot’s View of Rankine Cycle Creation of Temperature at constant pressure :

  8. Phase Behavior & Expenditure Vs Wastage Vapour Liquid +Vapour h Liquid s

  9. h Variable Pressure Steam Generation s

  10. Analysis of Steam Generation at Various Pressures

  11. More Availability of Energy for Turbine : Healthy Muscles

  12. Behavior of Vapour At Increasing Pressures All these show that the sensitivity of the fluid increases with increasing pressure.

  13. Creation/Reduction of Wastage

  14. Less Fuel for Creation of Same Temperature

  15. Availability of Steam for Condenser Temperature of 450C

  16. Ideal Rankine Cycle : p-h Diagram 3 2 1 4

  17. 3 3 3 2 2 2 1 1 1 4 4 4 Ideal Rankine Cycle : P-h Diagram

  18. Heat Addition in Steam Generator, qin Analysis of Steam Generation Process Define entropy based mean

  19. First Law Analysis of the Rankine Cycle • Main components of the above cycle are: • 1) Pump – Generate high Pressure water. •  2) Boiler (steam generator) – heat exchanger • 3)  Turbine – generates mechanical power • 4)   Condenser – heat exchanger

  20. Pump : Adiabatic Process 1 2 SSSF: Conservation of mass First Law : No heat transfer, change in kinetic and potential energies are negligible

  21. For SSSF Process: Liquids are incompressible, change in volume per unit change in Pressure is negligible.

  22. Pumping of Incompressible Fluids Adiabatic pumping of a liquid is almost an Isothermal process!!
