Fly ash Wikipedia
Fly ash or flue ash, also known as pulverised fuel ash in the United Kingdom, is a coal combustion product that is composed of the particulates (fine particles of burned fuel) that are driven out of coalfired 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.
