2021-9-1 · Fly ash (FA) is the principal industrial waste byproduct from the burning of solid fuels. FA is a powdery solid that is constituted mostly of unburned carbon (UC), metal oxides (Si, Fe, Ca, and Al), and other inorganic substances. UC is an inexpensive source of activated carbon that plays an important role in FA adsorption capacity.

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.
