Abstract

A method and apparatus for the separation of particles from a flow of gas, where both large, heavy and small, light particles are separated off from the gas by the combined effect of an electrostatic attraction force and a centrifugal force in a centrifugal separator of the type that comprises a rotor that has a plurality of adjacent surface elements with intermediate gas flow gaps and that is mounted in such a way that it can rotate in a surrounding casing, which casing has an inlet for unclean gas and an outlet for clean gas and an outlet for separated-off particles.
