Abstract
The invention relates to a centrifugal separator having a separation space with a set of separation plates, an inlet configured to feed a fluid product to be separated into the separation space, the inlet and the separation space being connected in a pressure mediating manner, a first and a second outlet extending from the separation space for discharge of a two phases of the product. A discharge control system is configured to trigger the opening of the second outlet upon a trigger condition, wherein the discharge control system comprises a sensor arranged to determine the inlet pressure and/or the inlet flow of fluid product, and the trigger condtion is associated with a decrease in inlet flow in relation to inlet pressure, indicating an increasing flow resistance downstream of the inlet. The invention further relates to a discharge control system and a method of controlling the intermittent discharge of a centrifugal separator.
