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 thermal efficiency?
What Is The Thermal Efficiency Formula?
1
Efficiency = Heat absorbed/work done by the engine.
2
η = W/Q1 = (Q1-Q2)/Q1.
3
= 1- (Q2/Q1)
4
The quantity of Heat absorbed is Q1.
5
The quantity of Heat was rejected in Q2.
6
W represents how much work the system has completed.
7
The engine will operate at total efficiency if Q2 is zero.
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.
