Chakravorty, U: Coal Dust Scrubbing

Present day water spray based dust removal technologies do not effectively remove respirable submicron coal dust particles in the underground coal mines causing Coal worker's pneumoconiosis (CWP). This research studies the inherent electrostatic charges present in the airborne coal dust in order to develop efficient water spraying based dust removal technology where water drops charged using ionic compounds and surfactants would be used to capture the oppositely charged coal particles. Characterization studies performed using an Aerodynamic Par ...
