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.
You can use fly ash in concrete production. Bottom Ash – Bottom ash is coarser than fly ash and is similar in texture to sand or gravel. Use bottom ash as an aggregate in concrete and asphalt applications, granular base in pavements, and in engineered embankments and fills. Boiler Slag – Boiler slag is a coarse, black, angular and glassy ...
