An analysis on the velocity of dust particles in the plate-type electrostatic precipitators used in thermoelectric power plants

Experimental data collected from different plate-type electrostatic precipitators used in a thermoelectric power plant has been analyzed. The following parameters were considered: the collection efficiency, average migration velocity of dust particles, velocity distribution of the gas in the input and output channels of precipitators. The average migration velocity of dust particles can be estimated using various mathematical models, and the gas velocity can be computed using the velocity distributions from the input channels of the precipitators. The traveling time of dust particles between the electrodes is smaller than the traveling time along the precipitator sections. © 2014, Technical University of Wroclaw. All rights reserved.
