Fly ash | Palamatic Process

Fly ash, also known as PFA ("Pulverized Fuel Ash"), is a waste product resulting from coal burning processes in industrial boilers and electric coal-fired boilers. The other two wastes products resulting from this combustion are "sub-hearth ash" and bottom ash. Ash is said to be "flying" in opposition to these two other types of waste.

The moisture content is approximately 5 to 15% w/w and the coal is slow-burning and difficult to ignite because of the high density - consequently few pulverized coal-fired plants use anthracite as the fuel. Anthracite is considered non-clinkering and free burning because (when ignited) it does not coke or expand and fuse together.
