The youngest coal is not even coal yet -- peat. Peat is a traditional fuel in parts of the world, like Ireland, where it is cut from the earth, dried, and burned for heat. The energy content of peat is quite low. Young coal is called lignite, and is soft and brown, not much different than dried peat.
Coal ash, also referred to as coal combustion residuals or CCRs, is produced primarily from the burning of coal in coal-fired power plants. Coal ash includes a number of by-products produced from burning coal, including: Fly Ash, a very fine, powdery material composed mostly of silica made from the burning of finely ground coal in a boiler.
