Geothermal energy

• Where GTE is from | Geothermal Power

  A) Geothermal reservoir (hot water in hot rock)

  B) hot rock

  C) very hot rocks

  D) hot rock

  E) water source

  F) fault

  G) cool water

  H) hot water

  I) heat

  
• Dry Steam Power Plant

  A) Turbine

  B) Generator

  C) electricity

  D) Condensed steam (water)

  E) Steam

  
• Flash Power Plant - Uses at least 200 degrees Celsius. Hot water rises from the reservoir and is flashed or turned into steam due to rapid drop in pressure. It is the most common type of power plant.

  A) hot water

  B) flash tank

  C) steam

  D) turbine

  E) generator

  F) electricity

  G) condensed steam (water)

  H) separated water

  
• Binary power plant - uses binary fluid with a lower boiling point to generate steam from geothermal heat, since the water temperature is below 200 degrees Celsius.

  A) Binary vapor

  B) turbine

  C) Generator

  D) electricity

  E) binary liquid

  F) heat exchanger

  G) cooled water

  H) hot water

  
• How power plants work:

  A) Geothermal zone

  B) Production well

  C) Injection well

  D) Cooling tower

  E) Air

  F) Air

  G) Water

  H) Waste brine

  I) Brine

  J) Steam

  K) High temperature steam

  L) Low temperature steam

  M) Turbine

  N) Generator

  O) Air & water vapor
