What is the efficiency of an organic Rankine Cycle?
The efficiency of current high temperature Organic Rankine Cycles does not exceed 24%. Typical steam Rankine cycles show a thermal efficiency higher than 30%, but with a more complex cycle design (in terms of number of components or size).
How to find cycle efficiency?
MCE = Value-added time / Total Cycle Time
A high MCE, meaning a large portion of the total time is spent on value-added work, indicates an efficient manufacturing process. Conversely, a low MCE suggests there are opportunities to reduce non-value-added activities and improve overall efficiency.
What is the actual efficiency of Rankine cycle?
Real Rankine cycle (non-ideal)
In particular, the efficiency of the steam turbine will be limited by water-droplet formation. As the water condenses, water droplets hit the turbine blades at high speed, causing pitting and erosion, gradually decreasing the life of turbine blades and efficiency of the turbine.
