What is Fly Ash? (with pictures) wisegeek

Jun 26, 2019Fly ash, also known as Pulverized Fuel Ash (PFA), is an industrial ash created when coal is burned to create electrical power. As the gaseous emissions of burning coal cool, some of its chemical constituents solidify into spherical granules, forming fly ash. A fine, glassy powder, its chemical components vary but usually include oxides of silicon (SiO 2), aluminum (Al 2 O 3), iron (several

When pulverized coal is combusted in a dry-ash, dry-bottom boiler, about 80 percent of all the ash leaves the furnace as fly ash, entrained in the flue gas. When pulverized coal is combusted in a wet-bottom (or slag-tap) furnace, as much as 50 percent of the ash is retained in the furnace, with the other 50 percent being entrained in the flue gas.
