The first radial centrifugal turbine has been installed in a binary geothermal power plant. The turbine was provided by Exergy for the plant operated by Enel Green Power in Bagnore, Mount Amiata, Italy.
The plant installed in Bagnore is of a binary type and uses a heat exchanger to transfer heat from the primary fluid (water mixed with steam) that comes out from the well to a secondary organic fluid. This vaporizes and turns the turbine connected to the alternator. The primary fluid is reintroduced into the ground while the cycle ORC itself is closed.
Exergy ORC will have a booth at the GEA Expo run in conjunction with the GRC Annual Meeting, Sept. 29-Oct. 2 at the MGM Grand, Las Vegas, Nevada.
