Abstract
Apparatus and method are provided for reducing rapping reentrainment from a conventional electrostatic precipitator. Thus, the apparatus will include a conventional electrostatic precipitator having at least one main electrical section and, in sequence downstream of the main electrical section, a precharger and a reentrainment collector. The precharger has a tubular anode aligned with collection plates in the main electrical section and a corona discharge wire aligned with the corona discharge wires of the main electrical section. The reentrainment collector includes collection plates substantially shorter than the collection plates of the main electrical section with at least one corona discharge wire in each of the gaps between the collection plates. The secondary collection plates of the reentrainment collector are operated at a current density 75% or less of the current density at which the main collector plates are operated.
