Abstract
A centrifugal separator and a method for separation of particles from a gas stream is disclosed. The separator includes a frame, a gas inlet and a gas outlet. A centrifugal rotor is arranged to be rotatable in the frame around a rotational axis and includes a separating member. A central gas chamber in the rotor communicates with a radially inner portion of the separating member and the gas outlet. A space surrounding the rotor communicates with a radially outer portion of the separating member and the gas inlet. A drive provides rotation of the centrifugal rotor for separating particles from the gas stream being conducted from the space surrounding the rotor, through the separation member and towards the central gas chamber. A ring-formed sealing arranged between and in sealing contact with the first frame portion and the centrifugal rotor. This improves the separation performance of a centrifugal separator for separation of particles from a gas stream, by reducing pressure losses and leakage from the central gas chamber.
