how does coal generate electricity

Coal & electricity

Steam coal, also known as thermal coal, is used in power stations to generate electricity Coal is first milled to a fine powder, which increases the surface area and allows it to burn more quickly In these pulverised coal combustion (PCC) systems, the powdered coal is blown into the combustion chamber of a boiler where it is burnt at high.

What is coal?

How does coal make electricity? Simply put, coal-fired electricity generation is a five-step process: Thermal coal (either black or brown) that has been pulverised to a fine powder is burned; The resulting heat is used to turn water into steam; The steam at very high pressure is then used to spin a turbine, connected to an electrical generator.
