How is Electricity Made? | How Does Electricity Work? - Just Energy

Coal-generated electricity is created using a "pulverized coal combustion system" (PCC). Coal is milled into a fine powder and is blown into a combustion chamber of a boiler and burned at a high temperature. The gases and heat energy produced converts water into steam. This steam passes through a turbine containing thousand of propeller ...

How Is Coal Converted to Usable Energy? - Reference.com

The conversion of coal begins in pulverized coal combustion systems, which start the process by steaming coal, which then turns into powder. In its powder form, coal is added to boiler combustion chambers, which heat the substance to high temperatures. This reaction produces hot gases and heat energy, which combine with water to form steam.
