Coal is first of all processed to remove all unwanted materials and then is crushed in to smaller pieces and fed into a furnace which heats a boiler containing water. The boiler is pressure controlled and so the steam generated is at very high temperatures(500 degree clecius or more). This steam is then used to move turbines which produce elcetricity.

Coal is used in power stations as fuel to drive the turbines that produce elecricity. I think they're like giant dynamos where the spinning action of wound coils of wire against magnetic"brushes" creates electricity, but check it out. Hope this helps

It is broken up into small pieces and fed by a conveyor belt into a boiler where it heats water going through tubes to steam which is used to drive a steam turbine. The steam turbine drives an electrical generator.
