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
