Designed for total heat inputs of approximately 2,000 to 8,000 kWth, the system primarily operates through a high‑temperature (HT) circuit, which accounts for about 90–95% of the heat input. Typical HT circuit temperatures range from 300 °C at the inlet to 240 °C at the outlet.
A secondary low‑temperature (LT) circuit contributes an additional 5–10% of the total heat input, with nominal inlet/outlet temperatures of around 240/140 °C. Together, these circuits drive the ORC turbine to produce a gross electrical output between roughly 350 and 2,000 kWel, depending on configuration.
The system’s own power consumption remains low, at about 5–6%, resulting in a gross electrical efficiency of approximately 19–20%.
In combined heat and power (CHP) applications, the turbine also delivers significant thermal energy at the cold end. The cooling‑water circuit typically operates with temperatures of 60/80 °C, making it well‑suited for integration into district heating networks. Up to 80% of the total heat input can be transferred to the district heating system, maximizing overall energy utilization and supporting highly efficient, sustainable heat‑and‑power production.
