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.

Organic Rankine Cycle-

• Major Components:-

• Boiler

• Steam turbine

• Re-generator

• Transformer

• Condenser

• Cooling tower

ORC- main components:-

Experimental Set up

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 orcpower plants

•Presence of recuperative system

WORKING FLUIDS:-

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

SOURCES OF WASTE HEAT:-

APLLICATIONS:-

• GEOTHERMAL POWER PLANT

• MICROTURBINE

• ORMAT ENERGY CONVERTER

• CEMENT POWER PLANT
