Treatment of Coal Ash

(1) At coal-fired thermal power station, coal broken down into powder form is combusted in a boiler, and that energy is converted into electricity. The coal ash particles melted by this combustion float in hot combustion gases; the particles become vitreous and round when the temperature drops outside the boiler and are collected by electric Get price
