What is the efficiency of the organic Rankine Cycle?
The fuel cell produces a power output of 1198 W at a current of 24A. It has 50% efficiency and hence produces an equal amount of waste heat. That waste heat is used to drive an organic Rankine cycle (ORC), which in turn produces an additional 428 W of power at 35% efficiency.
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.
