BT ENERGY offers Organic Rankine Cycle (ORC) technology as an advanced heat recovery system.
The ORC is named for its use of an organic, high molecular mass fluid with a liquid-vapor phase change, or boiling point, occurring at a lower temperature than the water-steam phase change. The fluid allows Rankine cycle heat recovery from lower temperature sources such as biomass combustion, industrial waste heat, geothermal heat, solar ponds etc. The low-temperature heat is converted into useful work, that can itself be converted into electricity.
With this improved technology BT Energy provides:
- Utility size solutions modules up to 15MW per unit
- Improved process performance (circa 51%)
- Reduced capital costs
- Full modularisation
- Rapid site installation
