FLY ASH GENERATION AND UTILIZATION AN OVERVIEW By Tarun R. Naik, and Shiw S. Singh ABSTRACT This chapter describes production and utilization of fly ash throughout the world. The utilization potential for fly ash generated from conventional as well as advanced coal combustion technologies are addressed.
Strategies for Ash Utilization A useful byeproduct ash in the form of fly ash, bottom or pond ash is available at the Coal and Lignite based thermal Power Plants. It needs to be utilized in various ways and applications. The future capacity addition will take into account the
Dec 18, 2010· b) ECONOMY IN USE OF FLY ASH. Use of fly ash in road works results in reduction in construction cost by about 10 to 20 per cent. Typically cost of borrow soil varies from about to 200 per cubic metre. Fly ash is available free of cost at the power plant and hence only transportation cost, laying and rolling cost are there in case of fly ash.
