Parametric Study on Production and Utilisation of Fly Ash in India

In India the generation of electricity mainly depend upon coal based power plant and would remain predominantly by coal based stations in the near future. The Indian coal is of low grade having high ash content of the order of 30-45% generating large quantity of fly ash at coal/lignite based thermal power stations in the country. After China, India is the second most country consumes large amounts of cement, which produces over 184 millions tones of fly ash per year with half of its in used. The management of fly ash has thus been a matter of concern in view of requirement of large area of land for its disposal because of its potential of causing pollution of air and water. Present paper has given an overview of production of Indian fly ash and utilisation of its discussed.
