Electricity production form coal based power plant is the cheapest and technologically suitable method. The use of coal in these power plant results in to production of fly ash. The extent of production of fly ash depends upon type and quality of coal used like lignite, anthracite bituminous and sub bituminous coal. The fly ash spreads around thermal power plant. The fly ash also dispersed off in the form of slurry or sludge, in the near by area of Thermal Power Plant i.e. at disposal sites.
