· Coal ash is a general term—it refers to whatever waste is leftover after coal is combusted, usually in a coalfired power plant. It contains arsenic, mercury, lead, and many other heavy metals.
D. Zhang, in UltraSupercritical Coal Power Plants, 2013. Thermodynamic equilibrium calculations. Thermodynamic equilibrium calculations or equilibrium phase diagrams are also used to provide information on the properties of coal ash or ash deposits, such as mineralogy, ash fusion temperatures (AFTs) and viscosity, or to predict the behaviour of coal ash during combustion. 27, 94, 106
Some Nigerian coals can be used to produce formedcoke of metallurgical quality. As a consequence of the privatisation drive by the government, the coal resources of Nigeria were delineated into 10 prospective blocks and placed for bidding by companies with proven financial and technical abilities.
Fly ash is a heterogeneous byproduct material produced in the combustion process of coal used in power stations. It is a fine grey coloured powder having spherical glassy particles that rise with the flue gases. As fly ash contains pozzolanic materials components which reach with lime to form cementatious materials. Thus Fly ash is used []

The impact of coal fly ash (CFA) exposure to the ecosystem and human health has not gone unnoticed. Is quiet very obvious that CFA disposal will continue unabated and will continue to constitute a
· Likewise, postcombustion of coal produced a lot of fly ash, bottom ash and slags, collectively known as coal combustion residue (CCRs) (Mishra, 2004). Fly ash introduced into the environment through transportation and the atmospheric mobility of fly ash over large distances, from the coal plant to the deposit and/or dumping site ( Raja et al., 2015 ), increases its impact on both
Fly ash particles are typically spherical in shape, either solid or with vesicles (Figure 2). A small percentage are thinwalled hollow particles called cenospheres. The particles are finegrained, Coal Ash: Characteristics, Management and Environmental Issues . 3 .

· Coal Fly Ash. I''m bringing up CFA because Alumina which is where Aluminum Oxide comes from, comes from CFA. Someone made a claim that a cloud came from the North of Paradise and reignited the fire on November 9th. He suspected it was Aluminum Oxide which is flammable but didn''t take into account the substance that AO comes from, Coal Fly Ash.
Although coal ash such as fly ash and bottom ash are, generally, disposed of to landfill as industrial waste, the efficient use of them is required due to landfill shortage. 80% of coal ash has ever been reutilized as cement raw materials in Indonesia; however, alternative proposal for effective use of them is needed in consideration of the increase in the amount of coal ash in the future.
· Coal ash is the powdery substance that remains after burning coal. What remains after coal is burned includes fly ash, bottom ash and socalled scrubber sludge, said Lisa Evans,
Coal fly ash has been immensely and widely used in this last application, for different kinds of soils, due mainly to its pozzolanic properties. Coal fly ash is an artificial pozzolan, a siliceous or siliceous/aluminous material that, when mixed with lime and water, forms a cementitious compound. Coal fly ash is the best known, and one

A major incentive for colonial rule in Nigeria were her natural resources and the wealth hidden beneath her soils, including large deposits of minerals strewn around the country. So alluring and wide spread were these deposits that it motivated the colonial government to amalgamate the territories now known as Nigeria for easier colonial management and transportation to Europe.
