  • Chapter 6 Agricultural Uses of Coal Combustion Byproducts

    During combustion, fly ash, bottom ash, and boiler slag are produced. Fly ash produced from the burning of coal has become a generic term for all types of coal combustion byproducts. Specifically, fly ash is that portion of the ash stream composed of particles small enough (0.001 to 0.1 mm) to be carried from the boiler in the flue gas.Learn More
