The diagram illustrates the necessary steps required to produce electricity by using coal as the main energy source.
The image depicts that coal undergoes various phases to produce electricity as we know it, this includes crushing and heating as the highlights of the process.
Initially, coal is stored in a container, when needed it is transferred through a belt to a pulveriser, where it is crushed into a fine substance. This powder is then heated under controlled temperatures in a hot furnace, above the coal product there is water passing through a pipe system, The main aim is to heat the liquid till it evaporates into vapours.
Next, after vaporisation, the pressure produced by this gaseous state helps rotate turbines in the next chamber,
this continuous movement helps generate electricity by charging a generator, subsequently activating a transformer which converts this charges energy to electricity. This electricity is then distributed to power lines and here on, used by the city.
