Geothermal power plant operating on high pressure geothermal fluid

Apparatus for producing power from high pressure geothermal fluid comprising:

• (a) means for producing steam using said geothermal fluid;
• (b) a primary steam turbine for producing power from steam produced from said geothermal fluid;
• (c) a moisture separator for separating moisture from heat depleted steam exiting said primary steam turbine and producing dried heat depleted steam and liquid;
• (d) a chamber that collects liquid produced in said moisture separator and flashes liquid in said chamber to produce steam;
• and
• (e) means for supplying said steam produced in said chamber together with said dried heat depleted steam to the inlet of a further steam turbine for producing power and further heat depleted steam.

A method for producing power from high pressure geothermal fluid comprising:

• a) producing high pressure steam using said geothermal fluid;
• b) expanding the high pressure steam in a high pressure turbogenerator for producing power and heat depleted steam;
• c) separating liquid from the heat depleted steam thereby producing dried heat depleted steam at a pressure and temperature lower than the pressure and temperature of the high pressure steam;
• d) combining the liquid so separated with heated water to form a mixture;
• e) flashing the mixture for producing flashed steam;
• and
• f) expanding said flashed steam and said dried heat depleted steam in a lower pressure turbogenerator for producing additional power.

Apparatus for producing power from pressure geothermal fluid comprising:

• (a) means for producing steam using said geothermal fluid;
• (b) a steam turbine responsive to said steam for producing power and wet, expanded steam;
• (c) a separator for separating said wet, expanded steam into dry expanded steam and separated water;
• (d) means for applying said dry expanded steam to a further steam turbine;
• and
• (e) means for converting heat in said separated water into power.

A method for producing power from geothermal fluid comprising:

• a) producing steam using said geothermal fluid;
• b) expanding said steam in a turbogenerator for producing power and heat depleted steam;
• c) adding heat to said heat depleted steam to form heated, heat depleted steam;
• and
• d) expanding said heated heat depleted steam in a turbogenerator for producing power.

A method for producing power from geothermal fluid comprising the steps:

• (a) producing steam using said geothermal fluid;
• (b) applying said steam to a steam turbine for producing power and heat depleted steam;
• (c) reheating said heat depleted steam for producing reheated heat depleted steam;
• (d) supplying said reheated heat depleted steam to the inlet of a further steam turbine for producing power and further heat depleted steam.
