A binary cycle is a type of power generation system that uses two different fluids to convert heat into electricity. In this process, a high-temperature heat source, such as geothermal energy or waste heat, heats a secondary fluid with a lower boiling point. This secondary fluid vaporizes and drives a turbine, generating electricity. After passing through the turbine, the vapor is cooled and condensed back into a liquid. The cooled fluid is then pumped back to the heat exchanger to be reheated, creating a continuous cycle. This method is efficient and can utilize lower temperature heat sources compared to traditional steam cycles.
