Waste heat recovery system – ORC-Organic Rankine Cycle technology.

Units working on the basis of thermodynamic Rankine cycle are widely used by conventional Power Plants. Approximately 85% of electrical energy is generated worldwide on the basis of Rankine Cycle. When using this cycle, thermal energy is transferred to the mechanical energy of turbine shaft rotation.

Advantages of ORC technology implementation There are several advantages of ORC-based units operation in comparison with units based on conventional steam/water cycle.

• Lower rotation speed and mechanical stress of the turbine; - Possibility to use direct drive for the generator (avoidance of losses in the reducer);
• Low noise and vibration levels;
• Significant operational resource and high operability (more than 50,000 hours of operation before the overhaul; non-stop operation
• more than 98% of time; maintenance period doesn't exceed one week in a year).
