Geothermal Energy from Bouillante, Guadeloupe
One important aspect of volcanoes is their heat. Sometimes this geothermal energy can be converted into electricity. The geothermal
power plant at Bouillante, Guadeloupe, generates power as follows:
This is the pipe system collecting the steam coming out from volcano's depths: How deep do the wells have to be? See next image!
How deep is the well? How much steam is harvested? What is the steam temperature? Why is the well inclined by 30 degrees (towards the volcano)? If the image above is too small use this enlargement.
The pipe in the foreground contains not only steam but also water droplets. Due to mixing with gases inside the volcano they are highly acidic. To avoid damage to the turbines, the steam must first be dried inside the tank behind the group.
This "monster" is the pump which pumps sea-water as a cold source for the heat exchange in the turbine.
|Geothermal power plants have also been successfully installed in other volcanic areas, for example, in Larderello, Italy, various sites in Iceland, Hawaii, Japan and New Zealand.|
