<p>PROBLEM TO BE SOLVED: To provide a power plant capable of increasing energy production by improving utilization efficiency of geothermal energy.SOLUTION: Provided is a geothermal power generation system in which, in a first supercritical pressure gas heating part, hot water separated at a gas-liquid separation part is thermally exchanged with a low-boiling medium of supercritical pressure heated at a second supercritical pressure gas heating part. In the second supercritical pressure gas heating part, steam extracted from a steam turbine is thermally exchanged with a low-boiling medium heated at a pseudo critical temperature heating part. In the pseudo critical temperature heating part, steam discharged from the steam turbine is thermally exchanged with a low-boiling medium of supercritical pressure heated at a supercritical pressure liquid heating part, allowing the steam to be discharged to the supercritical pressure liquid heating part after being condensed, and thereby the low-boiling medium is heated within a predetermined temperature range including a pseudo critical temperature.</p> |
