Dedusting

The ESP uses electrical forces to remove Particulate Matter (PM) from the flue gases. A high voltage source, generating a corona current, charges the PM which migrate to the collecting plate. PM are removed from the plate by a knocking action.

As for the dry ESP, the wet ESP uses electrical forces to remove Particulate Matter (PM) from the flue gases. A high voltage source, generating a corona current, charges the PM which migrate to the collecting plate. PM are removed from the plate by flushing water.

The Fabric Filter (or baghouses or bag filters) uses a filter media to separate Particulate Matter (PM) from the flue gases. The Particulate Matter are deposited at the surface of the fabric filter which may be made of different materials depending on the flue gas physical and chemical composition. The dust is removed periodically when cleaning the bags.

Hybrid Filter is a combination of ESP and FF with several configurations (in serie and in the same casing (integrated) or in separated casings in serie or in parallel (separated)).

ANDRITZ’s clean air technologies engineer – Mr. Jörgen Linnér from the Product Center Växjö (Sweden) – has received the Masuda award from the International Society for Electrostatic Precipitation (ISESP) for developing innovative uses and applications for Electrostatic Precipitator (ESP) technology.
