STEP # 1:

Coal is mined from the ground
and sent to coal power plants


                       There are
                     approximately
                    1100 coal mines
                   in North America
STEP # 2:
Coal is crushed into a
fine powder. So, it can
burn quicker



                          Crushing
                            coal
                          process
                          happens
STEP # 3:

The powder is blown into the
combustion chamber and it is
burnt at extreme temperatures


                            Burning
                            process
                          takes place
                             in the
                             boiler
STEP # 4:

The hot gasses and heat
produced converts the water into
steam from the water chamber



                            Water
                          adjacent to
                            boiler
STEP # 5:

steam then moves into a turbine
which contains propeller
blades, steam causes blades to
move at a high speed


                          Water Steam
                            travels
                           through
                           pipes to
                            turbine
STEP # 6:
• Generator is placed at the end of
the turbine, where tightly wound
wire coils are found. Electricity is
generated when coils are rotated
quickly.
• Strong magnetic field is produced



     Turbine and
    generator are
   adjacent to each
        other
STEP # 5:

Electricity is sent through power
grid lines and then travels to
substations located in towns.



                            House gets
                            electricity
                               from
                            substation
                             on their
                              street
Review:




THE CYCLE OF COAL TO ELECTRICITY
                                   1.   Coal is found
                                   2.   Coal is crushed to
                                        fine powder
                                   3.   Powder is burned
                                        in the boiler
                                   4.   Hot gasses and
                                        heat change water
                                        to steam
                                   5.   Steam travels to
                                        turbine and causes
                                        to propellers to
                                        spin at high speeds
                                   6.   At the end of
                                        turbine , there is a
                                        generator which
                                        contains coils
                                        which spin and
                                        produce electricity
                                   7.   Electricity is
                                        distributed by
                                        power grid lines
