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 efficiency of Rankine cycle?
Efficiency of Rankine Cycle
1
WT = Mechanical work done by the turbine.
2
WP = Mechanical work done by the pump.
3
h1, h2, h3, and h4 = Specific enthalpies of water at states 1, 2, 3, and 4 respectively referring to the T-s diagram in figure 2.
4
hf = Specific enthalpy of water = h (In this cycle)
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.
What is the difference between Rankine cycle and organic Rankine cycle?
An organic Rankine cycle (ORC), is fundamentally the same as a steam Rankine cycle; however, it uses a lower boiling point organic fluid to better match its operation to lower temperature heat sources. ORC systems can achieve better efficiencies than steam turbines for smaller systems (less than a few MWe).
* The efficiency of the ORC system is always optimized: on average at 50% load, electrical efficiency is still 90% of the nominal electrical efficiency.
