Abstract
A centrifugal separator for clarification of a liquid mixture into a heavy phase and a light phase, having a centrifugal separator bowl rotatable around an axis and encasing a separation space, and a sludge space radially outward of said separation space. The centrifugal separator bowl includes a hermetic inlet for feeding a liquid mixture to said separation space; a first hermetic outlet for a separated clarified light phase; and a second hermetic outlet for a separated heavy phase; a plurality of outlet conduits extending from an outer position in said sludge space to said second hermetic outlet. Each of the outlet conduits has a flow restriction in the form of a nozzle or vortex diode. A method to control such a centrifugal separator, in order to provide a stable flow through said outlet conduits, is also disclosed.
