Fly Ash is by product generated during combustion of coal, and comprises the fine particles that rise with the flue gases. Ash which is collected from the bottom is termed bottom ash. Fly ash is collected by electrostatic precipitators or other particle filtration equipment before the flue gases reach the chimneys of coal-fired power plants and together with bottom ash removed from the bottom of the furnace is in this case jointly known as coal ash. Depending upon the type of coal being used, the specification of Fly Ash varies considerably, but Fly Ash contains substantial amounts of silicon dioxide and calcium oxide (CaO), both being endemic ingredients in many coal-bearing rock strata. We are a reputed Fly Ash Exporter based in India and are supplying Fly Ash different cement, ready mix concrete, steel, refractories and construction industries.
The Major Utilization Areas Of Fly Ash :
- Manufacture of Portland Pozzolanic Cement & Performance improver in Ordinary Portland cement (OPC).
- Part replacement of OPC in cement concrete.
- High volume Fly Ash concrete.
- Roller Compacted Concrete used for dam & pavement construction.
- Manufacture of ash bricks and other building products.
- Construction of road embankments, structural fills, low lying area development.
- As a soil amender in agriculture and wasteland development.
Types of Fly Ash:
- According to the type of coal used fly is classified into two types. Anthracite and bituminous coal produces Fly Ash classified as class F. Class C Fly Ash is produced by burning lignite or sub-bituminous coal. Class C Fly Ash has self-cementing properties.
- Class F and Class C Fly Ash are products of the combustion of coal in large power plants. Fly Ash is collected in electrostatic precipitators or baghouses, and then transferred to large silos for shipment. When needed, Fly Ash is classified by precise particle size requirements, thus assuring a uniform, quality product.
- Class F Fly Ash is available in the largest quantities. Class F is generally low in lime, usually under 15 percent, and contains a greater combination of silica, alumina and iron (greater than 70 percent) than Class C Fly Ash.
- Class C Fly Ash normally comes from coals which may produce an ash with higher lime content generally more than 15 percent often as high as 30 percent. Elevated CaO may give Class C unique self-hardening characteristics.
