An Organic Rankine Cycle (ORC) system is a closed thermodynamic cycle used for power production from low to medium-high temperature heat sources ranging from 80 to 400°C and for small-medium applications at any temperature level.

What is the temperature range of the organic Rankine cycle?
Applicable fluid heat sources are between 70°C and 150°C. Gaseous heat sources above 150°C can also be used with the deployment of a secondary heat exchange loop. Our low-temperature ORC solutions use hot water as fuel in order to generate up to 125 kWe of clean electricity, at no additional cost to the operator.
What temperature does Rankine cycle work at?
The Rankine cycle applied using a supercritical fluid combines the concepts of heat regeneration and supercritical Rankine cycle into a unified process called the regenerative supercritical cycle (RGSC). It is optimised for temperature sources 125–450 °C.
What is the range of Rankine cycle?
Technology | Power Cycle | Performance Level |
Steam turbine | Rankine cycle | 30-40% |
Gas turbine | Brayton cycle | 30-40% |
Combined cycle | Brayton topping/Rankine bottoming Diesel cycle | 45-60% |
Diesel | Diesel cycle | 40-50% |
What is Q in Rankine cycle?
Efficiency of Rankine Cycle
Let us consider these terms that are essential to calculate the efficiency of the cycle. Q = Rate of heat flow in the system (towards or away) WT = Mechanical work done by the turbine. WP = Mechanical work done by the pump.
