The quantity of coal ash produced at coalfired thermal power plants varies from 5% to 45% depending on the type and source of coal used as fuel in the furnace. The coal ash produced at coalfired thermal power plants is classified into two types,, fly ash (FA) and bottom ash.
Fly ash (FAB) is a building material, specifically masonry units, containing class C or class F fly ash and water. Compressed at 28 MPa (272 atm) and cured for 24 hours in a 66 °C steam bath, then toughened with an air entrainment agent, the bricks last for more than 100 freezethaw cycles.
