Steam Energy

Energy that comes fromthe push of steam

3

When water boils,it turns into a gas

This gas is calledsteam

4

Steam can push objects and move

them

Any matter that is moving is using

mechanical energy

5

Steam is a source ofmechanical energy

6

Steam is madein a boiler

A boiler has a large tankand a furnace

7

The tank holds water,and the furnace burns fuel

to heat the water

Coal, oil, and wood are three (3)kinds of fuel used to

produce steam

8

When the fuel burns,the chemical energy stored in it

changes into heat energy

The heat energyheats the water in the boiler

andchanges it into steam

9

You have learned that wind and water

can turn wheels with blades

Steam can also turn wheels with blades

10

Steam Turbine

A kind of wheel with bladesthat is moved by steam

11

The energy from steam turbinescan be used in many ways

12

Many large shipsget their energy from

steam engines

The steam turbines on these ships

turn the ships’ propellers

13

Propellers make the shipsmove through the water

14

Steam turbinesare also used to make

electricity

Energy from the turbinesis used to run generators

which make electricity

15

Many large electric power plantshave steam turbines
