<p>A cyclone separator (10) having an inlet with inner and outer profiles (84, 82), viewed in section transverse to the separator axis. This location of any particular point on the outer profile (82) is defined by a vector contained in a plane normal to the separator axis, and having its origin at a location (C) where the outer profile meets the adjacent inner circumference (86) of the separator. As the magnitude of the vector (T) increases, an angle (6) between the vector (T) and a tangent (92) to the circumference (C) which passes through location (C) never decreases and never becomes less than zero. The location of any particular point on the inner profile (84) is defined by a vector (U) having its point of origin at a location (E) where the inner profile or at least its projection meets the separator circumference (86). As the magnitude of vector (U) increases, an angle ( zeta ) between vector (U) and a tangent (93) to the circumference (86) which passes through location (E) never decreases and never becomes less than zero, at least for substantial magnitudes of vector (U). Further modification of the separator is the end wall of the separating chamber portion (14) adjacent overflow outlet (25) is formed of curved configuration. A still further modification is where overflow outlet (25) is formed from a duct (27) which extends through the end wall into the separating chamber (14) a short distance. <IMAGE></p> |
