The specific resistance of the dust is an index for evaluating the conductivity, and has a direct influence on the dust removal efficiency. The specific resistance is too low, and dust particles are difficult to retain on the dust collecting electrode, so that they are returned to the air flow. The specific resistance is too high, the dust particle charges reaching the dust collecting electrode are not easy to discharge, and the local breakdown and discharge phenomena are generated by forming a voltage gradient between dust layers. Both of these cases cause a decrease in dust removal efficiency.
