They use the hot brine to vaporize a motive fluid such as liquid pentane in the heat exchanger, when the liquid is converted to gas it creates a high pressure environment and is piped into a turbine which spins the generator. Then they condense the motive fluid back to a liquid so they can vaporize it again. It's the same way binary geothermal power works, with the Organic Rankine Cycle. http://en.wikipedia.org/wiki/Organic_Rankine_cycle |
