Basic Electrostatic Precipitator (ESP) Operation

For recovery boilers, precipitators are used to collect the residual salt cake in the flue gas. A recovery boiler is a unique application for a precipitator due to the small particulate size and the tendency for the cohesive ash particles to stick together. The resistivity of the
