Abstract

A centrifugal separator for separating particles from gas uses a separator chamber having an upper potion with at least three substantially vertical planar walls with perpendicular inner faces, and a lower portion, for defining in the chamber a vertical gas vortex. The gas vortex has an inlet formed in the vicinity of a first corner between the first and second walls for gas to be dedusted, an outlet for dedusted gas, and an outlet for separated particles. The separator uses an acceleration duct with a first transverse section at the first end of the duct that is distinctly greater than a second cross section at the second end. This second end is connected to the inlet for gas to be dedusted at the first corner.
