How Is Coal Converted to Usable Energy?

Apr 04, 2020 · 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.
