Fly ash Energy Education

Fly ash is a coal combustion product.It is part of a set of products that makes up the most abundant waste materials worldwide. If not collected, this waste material is blown out with the flue gas in a coal fired power plant.Fly ash exists after combustion because ash adheres to coal, making up between 1-15% of its weight. About 90% of the ash is fly ash, while 10% is bottom ash.
