Organic Rankine Cycle (ORC) Systems for Combined Cycles - Energy
In combined cycles, Turboden ORC units can be installed downstream of gas turbines and reciprocating engines, producing electricity by recovering waste heat. In both cases the combined cycle achieves an efficiency greater than 50%. The power of Turboden turbogenerators in this application generally ranges up to 20 MW electric per single shaft.
In combined cycles, Turboden ORC units can be installed at the bottom of:
- Gas turbines, with up to 40% of additional power
- Reciprocating engines, with up to 15% of additional power
In both cases the combined cycle reaches an efficiency greater than 50%.
WHY ORGANIC RANKINE CYCLE TECHNOLOGY?
- Efficient use of high-to-low grade and variable heat sources
- Low operational costs and no water needed
- Add a reliable source of power, even in remote locations
- Improve power plants’ efficiency with a lower impact on Levelized Cost of Electricity (LCOE)
Designed upon specific site features, the ORC-based heat recovery system exploits the prime movers' exhausts to produce up to 30% ÷ 40% of additional useful power. The ORC system follows the prime movers' operation mode producing additional power (for the plant itself or for external users) without any impact on the power plant operation.
