    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 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.
