Abstract
A centrifugal separator for cleaning gas containing contaminants includes a stationary casing, enclosing a separation space through which a gas flow is permitted, a gas inlet extending through the stationary casing and permitting supply of the gas to be cleaned, a rotating member including a plurality of separation members arranged in said separation space and being arranged to rotate around an axis of rotation, a gas outlet configured to permit discharge of cleaned gas and including an outlet opening through a wall of the stationary casing, a drainage outlet configured to permit discharge of liquid impurities separated from the gas to be cleaned, and a drive member, for rotating the rotating member. The centrifugal separator further includes a control unit configured to control the drive member to rotate the rotating member at a first speed during a separation phase and at a second speed, which is higher than the first speed, during a cleaning phase to remove clogging on or between said separation members, wherein the cleaning phase is shorter in time than the separation phase.
