Coal ash is a major component of solid residue resulting by coal-fired thermal power plants. Trace elements like Mn , Cu , Zn , As , Se , Mo and Pb in fly ash and pond ash samples collected from ten coal-fired thermal power plants in India, and crops (rice, wheat, maize grain and straw and onion bulbs) grown on coal ash treated soils at Angul, Bakreswar and Farakka sites of India have been analysed at Institute of Physics by Particle Induced X-ray Emission and Energy Dispersive X-Ray Fluorescence techniques. Our analysis shows that the concentrations of trace elements of grains are higher than in straws. Increasing trends in the uptake of micro-nutrients by the crops due to application of coal ash, were recorded, but within permissible limits.

The process of coal combustion results in coal ash, 80% of which is very fine in nature & is thus known as fly ash. Presently, in India, about 120 coal based thermal power plants are producing about 90-120 million tons of fly ash every year. With increase in demand of power energy, more and more thermal power plants are expected to commission in near future and it is expected that fly ash generation will be 225 million tons by 2017. Disposal of fly ash requires large quantity of land, water and energy and its fine particles, if not disposed properly, by virtue of their weightless, can become air born and adversely affect the entire Environment. These earth elements primarily consist of silica, alumina & iron etc. and its physicochemical parameters are closely resembles with volcanic ash, natural soil etc. These properties, therefore, makes it suitable for use in ceramic industries and helps in saving the environment and resources.

<p class="TTPTitle"><span>The paper presents the data on a structure of conventional fuels consumption, as well as a structure of fossil fuel consumption at thermal power plants (TPPs) in Russia. The issue of applying the Best Available Technologies (BAT) in Russia is touched upon. Statistics on production and utilization of coal ash in Russia and other countries is given. The paper provides information on the status and terminology of coal ash in different countries. It contains an impact of terminology on the effectiveness of solving the coal ash handling problem in Russia. The paper includes a new legislative definition of coal ash produced at thermal power plants and boiler houses of Russia which meets modern conditions and global trends, as well as requirements for coal energy sector.</span></p>
