Abstract: Described is a cyclone separator comprising a cyclone housing (1), a discharge duct (5) and a central tube (3) for diverting gases, said central tube (3) extends axially into the cyclone housing (1) and being composed by a number of segments (3a) which are suspended on a supporting element (15) provided in the area between the cyclone housing (1) and the discharge duct (5). The cyclone separator is peculiar in that it comprises a number of carrying means (17) which are evenly distributed and fixed to the inner side of the cyclone housing (1) and/or the discharge duct (5), and in that the supporting element (15) comprises an annular disc which is loosely fitted on top of the carrying means (17) and having an outer diameter which is smaller than the inner diameter of the cyclone housing (1) and/or the discharge duct (5) so that a clearance (18) is provided between the annular disc (15) and the cyclone housing (1) and/or the discharge duct (5). Hereby is obtained a significant reduction in the heat transmission from the supporting element to the cyclone housing and/or the discharge duct so that the radial temperature gradient in the supporting element is reduced with an approximately uniform temperature over the radial cross section of the element. Hence the thermal stresses in the supporting element will be substantially reduced. This is mainly ascribable to the reduction in the contact area between the supporting element and the cyclone housing and/or the discharge duct.
