Paper Title
Management and Utilization of Fly Ash Over Last Few Years In India: A Review
Authors

Abstract
Fly ash is a fine particle that is principally a secondary product of coal combustion and other waste materials that are driven out of the boiler with the flue gases. The fine particles that are deposited at the bottom are called bottom ash. Fly ash is nothing but a by-product of burning pulverized coal in an electrical generating station (Thermal Power Plants, TPP’s). Specifically, it is the unburned residue that is carried away from the burning zone in the boiler by the flue gases and then collected by either mechanical or electrostatic separators. Disposal of Fly Ash is one of the concerns for Thermal Power Plants. Proper disposal of fly ash is not so easy and if in case, fly ash collection systems are not very efficient enough, a portion of it escapes into the atmosphere causing environmental pollution. To overcome this seriousness, Government of India notified FlyAsh Notification on 14th September, 1999 and its subsequent amendments. The main objective of FlyAsh Notification is to protect the environment, conserve top soil and prevent the dumping and disposal of fly ash discharged from coal or lignite based thermal power plants on land. Another major reason for the Notification is to restrict the excavation of top soil for manufacture of bricks and promoting the utilization of fly ash in the manufacture of building materials and in construction activity within a specified radius from coal or lignite based thermal power plant. Utilization of fly ash can result not only in reducing the magnitude of the environmental problems, but it is also to exploit fly ash as raw material for value added products (and conserve traditional materials), and for extraction of valuable materials.
