Abstract
A cyclone separator having a generally cylindrical first portion with a plurality of tangentially directed feeds, and, adjacent to the first portion and coaxial therewith, a generally cylindrical second portion open at its far end, the first portion having an axial overflow outlet opposite the second portion, the second portion opening at its far end into a coaxial generally cylindrical third portion, the internal diameter of the axial overflow outlet being d.sub.0, of the first portion being d.sub.1, of the second portion being d.sub.2 and of the third portion being d.sub.3, the internal length of the first portion being l.sub.1 and of the second portion being l.sub.2, wherein the total cross-sectional area of all the feeds measured at the points of entry normal to the inlet flow is A.sub.i and wherein the shape of the separator is governed by the following relationships: PA1 10.ltoreq.l.sub.2 /d.sub.2 .ltoreq.25 PA1 0.04.ltoreq.4A.sub.i /.pi.d.sub.1.sup.2 .ltoreq.0.10 PA1 0.1.ltoreq.d.sub.0 /d.sub.2 .ltoreq.0.25 PA1 d.sub.1 >d.sub.2 PA1 d.sub.2 >d.sub.3.
