flash-steam geothermal plant
A type of geothermal steam plant.
When the temperature of the hydrothermal liquids is over 350°F (177°C),
flash-steam technology is generally employed. In these systems, most of
the liquid is flashed to steam. The steam is separated from the remaining
liquid and used to drive a turbine generator. While the water is returned
to the geothermal reservoir, the economics of most hydrothermal flash plants
are improved by using a dual-flash cycle, which separates the steam at two
different pressures. The dual-flash cycle produces 20% to 30% more power
than a single-flash system at the same fluid flow.
