The Organic Rankine Cycle (ORC)

ORC Main Components

Advantages of ORC

• Completely automated – no operator

• Very low O&M Costs

• Simple Start/Stop procedures

• Maintains good efficiency at partial load

• Low turbine RPM, low mechanical stress

• Can reach efficiencies up to 25%

• Do not consume water

• Remotely monitored and controlled

• Turn-down to 10% of nominal power

• Quiet Operation
