Geothermal Energy ..

1. Geothermal Energy
Some Technical Aspects About
By: Ahmed Tarek Mohamed

2. Definition:
Geothermal energy is energy extracted from
the heat stored in the earth.
Geothermal Power
Electricity Production

3. Heat sources:
Earth’s internal heat
(Heat loss)
Radioactive decay
(Heat gain)

4. Tectonic activity and Geothermal energy

5. Structure of the Earth
Geothermal Gradient:
Is the difference in temperature between the core
of the planet and its surface.

6. Heat Extraction and Geothermal reservoirs

7. Main Components of a Geothermal Power Plant:
■ Production Well
■ Separator
■ Heat Exchanger
■ Steam Turbine
■ Condenser
■ Generator
■ Injection Well

1. Geothermal springs are occur along the eastern and western
margin of the Suez Gulf (at Hammam Faraun, Ayoun Mousa and
Ain Sukhna).
2. Radiogenic HHP granites of the eastern desert.
