Dust emission reduction

Dust emission reduction at Grass and Alfalfa dryers is becoming more important every year.

Dutch Dryers has gained a lot of experience with installation of dust emission reduction cyclones at several dryers in Europe. The best results are obtained by the combination of a high efficiency main cyclone in combination with very high efficiency multicyclones.

The combination of these cyclones makes it possible to reduce the dust emission of Alfalfa and grass dryers to approximately 50-75 mg/Nm³ wet to meet the new emission limits given by local authorities.

The above-mentioned techniques are also possible in combination with biomass furnaces as well as with energy consumption reduction measures like drying air recirculation.
