Fly ash Wikipedia

Fly ash or flue ash, also known as pulverised fuel ash in the United Kingdom, or coal combustion residuals (CCRs), is a coal combustion product that is composed of the particulates (fine particles of burned fuel) that are driven out of coal-fired boilers together with the flue gases.Ash that falls to the bottom of the boiler's combustion chamber (commonly called a firebox) is called bottom ash.

22/09/2016 South African Bureau of Standards (SABS) defines fly ash as the powdery residue obtained by separation of the solids from the flue gases of furnaces fired with pulverized coal. Coal fly ash consists of many small (0.01–100 µm diameter) glass-like particles of a generally spherical character. The fineness of fly ash particles depends largely on the combustion temperature, the grinding size

Value in Waste: Fly Ash Reuse and Recovery Opportunities

One of the primary targets for recovery from fly ash has been alumina; most fly ash contains between 25 30% aluminum oxide (Al 2 O 3)¹. Some sources of fly ash in China have been shown to contain as much as 45% alumina. ² In addition to its use in producing aluminum metal, alumina is used throughout a host of industries as a catalyst, pigment, abrasive, and a long list of other materials.
