The diagram illustrates the coal plant process, outlining
from plants taken by a truck all the way through to producing electricity for
transmission system.
Generally, a waste plant is used for the process, which is
brought by a truck to the factory site. The plant then is crushed by a crusher,
where the process is repeated twice to ensure it is completely degraded. The
degraded plant then is taken by a conveyor to a silo, where it is stored before
further used for the next step.
Once ready, the degraded plant is taken to a boiler, where it
is used as a burning material called fireball, used to boil water. The boiling
water then turns into steam, where then it
which is further superheated. This allows vigorous steam movement that
drives the turbines placed next to the boiler. At the same time, the excessive
steam condenses into water, which is continually recycled for the boiling
purpose.
As the turbines are spinning, they produce energy which
ignites the generator to produce electricity. Then the power is sent to a transformer
before further being transferred
to a transmission system, where the electricity is allocated for public used.
