Clean Air Technologies for Biomass industry

Biomass, as a fuel for renewable or sustainable energy generation, requires a variety of proven clean air technologies.

Please find below an overview of the best available technologies ANDRITZ can supply to reduce emissions from this industry.

Dry Electrostatic Precipitator (ESP)

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.

Fabric Filters (FF)

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.

Selective Non-Catalytic Reduction (SNCR)

In the SNCR system, a reducing agent, typically ammonia or urea, is used to convert the NOx emissions (without catalysts) into harmless nitrogen (N2) and water vapor (H2O).
