Question 9

It is described schematically as convecting water in the upper crust of the Earth which in a confined space transfers heat from a heat source to a heat sink usually the free space.

Answer 9

Geothermal system

Question 10

The geothermal system is composed of three main elements:

Answer 10

Heat source, resservoir and fluid

Question 11

It can be either a very high temperature magmatic intrusion that has reached a shallow depth of 5-10 km or as in certain low-temperature systems, the Earth’s normal temperature which as we understand increases with depth.

Answer 11

Heat source

Question 12

A volume of hot permeable rocks from which the circulation fluids extract heat.

Answer 12

Reservoir

Question 13

This component is generally below a blanker of impermeable rocks and connected to a recharge area through which the meteoric waters can replace the fluids that escape from the reservoir through springs or boreholes.

Answer 13

Reservoir

Question 14

It is the carrier that transfers the heat. It often carries with it other chemical and gas compounds such as carbon dioxide, hydrogen sulfide, etc.

Answer 14

Geothermal fluid (Water)

Question 15

The mechanism that governs this geothermal system is known as

Answer 15

Fluid Convection

Question 16

It takes place due to the heating and consequent thermal expansion of fluids in a gravity field.

Answer 16

Convection

Question 17

It is like a regular power plant except that no fuel is burned to heat water into stea,.

Answer 17

Geothermal Power Plant

Question 18

It is drilled into a geothermal reservoir.

Answer 18

Production well

Question 19

To allow the return of used geothermal fluids to the geothermal reservoir, an ________ is also drilled.

Answer 19

Injection Well

Question 20

Is allowed to generate rapidly and provide rotational or mechanical energy to turn the turbine blades on a shaft.

Answer 20

Hot pressurized geothermal fluid or Secondary Working Fluid

Question 21

What are the 2 primary pieces of equipment are used to convert geothermal energy to electrical energy?

Answer 21

Turbine and Generator

Question 22

It is sent to a step-up transformer outside the power plant.

Answer 22

Electrical current from the generator

Question 23

It is increased in the transformer and electrical current is then transmiited over power lines to homes, buildings, and business establishments.

Answer 23

Voltage

Question 24

IS
HEAT WITHIN THE EARTH.

Answer 24

Geothermal Energy

Question 25

THE WORD GEOTHERMAL COMES FROM THE GREEK WORDS:

Answer 25

**GEO** which means **Earth** and **THERME** which means **Heat**

Question 26

IS A RENEWABLE ENERGY SOURCE BECAUSE HEAT IS CONTINUOUSLY PRODUCED INSIDE THE EARTH.

Answer 26

Geothermal energy

Question 27

As the name implies these are reservoirs of **hot underground water.** There is a large amount of them in the US, but they are more suited for **space heating than for electricity production.**

Answer 27

Hot Water Reservoirs

Question 28

A hole dug into the ground can cause steam to come to the surface. This type of resource is rare in the US.

Answer 28

Natural Steam Reservoirs

Question 29

These were the first type of plants created. They use underground steam to directly turn the turbines.

Answer 29

Dry Steam Power Plants

Question 30

These are the most common plants. These systems pull deep, high pressured hot water that reaches temperatures of 360F or more to the surface. This water is transported to low-pressure chambers, and the resulting steam drives the turbines. The remaining water and steam are then injected back into the source from which they were taken.

Answer 30

Flash Steam Power Plants

Question 31

This system passes moderately hot geothermal water past a liquid, usually an organic fluid, that has a **lower boiling point.** The resulting steam from the organic liquid drives the turbines.

Answer 31

Binary Cycle Power Plants

Question 32

This process does not produce any emissions and the water temperature needed for the water is lower than that needed in the Flash Steam Plants (2500F – 3600F).

Answer 32

Binary Cycle Power Plants

Question 33

Are pools of water heated by magma deep below the surface.

Answer 33

Geothermal Reservoirs

Question 34
