Abstract
A cyclone for treating a gas flow (F) containing dust comprises a cyclone chamber (1) of circular cross section and having a vertical axis, and a central tube (7) of circular cross section, which is coaxially arranged in the upper portion of the cyclone chamber (1). An elongated insert element (10), which is vertically inserted in the central tube (7), is so designed and extends in such a manner downwards in the central tube (7) from the upper end thereof that a circumferential gap (17) exists between the insert element (10) and the central tube (7). This gap (17) has a preferably constant cross-sectional area which does not increase in the direction of the gas flow.
