Fossil Electrical Energy

Coal power plants

A coal power plant produces electricity using the heat generated by the combustion of coal.

Coal is a fossil fuel of organic origin. It is the result of the transformation of forest residues buried in the soil for nearly 300 million years (Carboniferous era). By burial, under the effect of high pressure and temperatures due to the depth, the buried plants decomposed and then transformed into a solid and combustible material with high carbon content:  There are several categories of coal depending on the level of carbon, sulfur and water they contain.

Coal power plants use this energy source to generate electricity. After being sorted and washed, the coal is burned in a boiler. The heat generated by this combustion heats the water until it turns into steam. This steam drives a turbine which, together with an alternator, generates electricity.
