Organic Rankine Cycles (ORC) are systems that can effectively recover low-grade heat for electric power generation. For ORC to be a viable technology, it should operate safely and efficiently under variable operating conditions due to exogenous and operating specifications changes.

Organic Rankine Cycle Solutions for Power Generation with Turbogenerators. The ORC (Organic Rankine Cycle) system is based on an innovative closed thermodynamic cycle for the flexible and distributed production of electric and thermal power.

The minimum operating temperature is 90 °C, and it can complement the electrical generation with the production of useful heat with temperatures of up to 50 °C. When the heat source temperature of the ORC machine is between 120 °C and 150 °C, Rank® MT equipment offers excellent electrical performance.

The organic Rankine cycle is is similar to the Rankine steam cycle, but uses an organic fluid such as refrigerants and hydrocarbons instead of water as the working fluid. The ordinary Rankine cycle uses thermal power to convert water to steam, which expands through a turbine in order to generate electricity.
