Coal ash, also referred to as coal combustion residuals or CCRs, is produced primarily from the burning of coal in coalfired power plants. Coal ash includes a number of byproducts 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.
The bituminous coal is a dense sedimentary rock. Generally its black but sometimes, it can be darkbrown. It has got several uses. First, it is used in steam electric power generation as fuel. It can also be used in manufacturing for heat and power applications, and to make coke. Steam coal is the halfway between bituminous and anthracite.

Coal Basics What is coal? Coal is a solid fossil hydrocarbon that represents the storage of solar energy from the past in the form of preserved plant material. The plants during the preservation process have been broken down into organic matter that comprises moisture, ash, volatile matter (gases and liquids given off on heating) and fixed carbon.

Lignite increases in maturity by becoming darker and harder and is then classified as subbituminous coal. After a continuous process of burial and alteration, chemical and physical changes occur until the coal is classified as bituminous dark and hard coal. Bituminous coal ignites easily and burns long with a relatively long flame. If improperly fired bituminous coal is characterized with excess smoke and soot.
