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 calculate cycle efficiency?
To calculate cycle efficiency, divide Value-Added Production Time by the Total Cyle Time. For reference, Total Cycle Time is the summation of all activities associated with the work on a unit from start to finish.
What is the overall efficiency of the Rankine cycle?
Answer: (ηT)Rankine = 30.4% (there is no change in (ηT)Rankine to three significant figures). Note that the interstage reheating used in Example 13.7 increases the Rankine cycle thermal efficiency by only 0.8%. However, it has the much more important effect of reducing the moisture content at the turbine exit.
