2. Introduction
• Organic Rankine Cycle focuses on low temprature waste
heat recovery
• Orc uses organic,high molecular mass fluid with a
liquid-vapor phase change occuring at low temp
• Orc allows low temp sources like biomass combustion,
industrial waste heat ,solar ponds , geothermal energy
• Orc resembles steam cycle and here water is replaced
with organic fluid.

3. Organic Rankine Cycle-
• Major Components:-
• Boiler
• Steam turbine
• Re-generator
• Transformer
• Condenser
• Cooling tower

5. ORC-main components:-

6. Experimental Set up

8. EFFICIENCY OF ORC
•High molecular weight of working fluid increases
the mass flow rate of it
•Unlike steam ,organic fluids doesn’t erodes or
corrodes the turbine blades
•Problems of high costs for machinery are
overcome due to low working pressure in orc
power plants
•Presence of recuperative system

9. WORKING FLUIDS:-
*Generally dry fluid and isentropic fluids are
recommended in orc.
*Choose the temp closest to the waste heat source.

10. SOURCES OF WASTE HEAT:-

11. APLLICATIONS:-
• GEOTHERMAL POWER PLANT
• MICROTURBINE
• ORMAT ENERGY CONVERTER
• CEMENT POWER PLANT
