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.
What is fly ash?
Fly Ash is a by-product of coal based thermal power station generated by the combustion of pulverized coal. Fly Ash is a fine, grey, amorphous powder. It is rich in silica & alumina and spherical in shape. The properties of Fly Ash may vary widely, both physically and chemically, depending upon the nature of coal, the efficiency of coal combustion process and the selection process.
Therefore, it is important that when considering the use of Fly Ash to look no further than a company with the in-depth technical knowledge and support to manufacture and supply a high-quality product.
The Fly Ash that we supply is sourced from well-known companies. Our Fly Ash is ensured to be pure and free from impurities. We have been able to earn a reputed place among the well-reckoned Fly Ash Suppliers in India. We offer Fly Ash in different quantities as per the requirement of the client.
