Cyclones to lessen fouling

Claim 1

A cyclone separator including an elongated barrel, a transition piece and a dipleg, an inlet for introducing solidladen gases tangentially into the barrel, an outlet for removing separated gases from the barrel, an outlet for removing separated solids from the transition piece and dipleg, and baffle means for reducing the residual centrifugal forces of the separated solids, said baffle means being located below the outlet for removing separated gases at a distance which is equal to or greater than half the length of said barrel, and said baffle means comprising a cone part and a plurality of fins having upper and lower fin sections mounted axially on a shaft, said shaft being centrally positioned within the cyclone so that the cone part and upper fin sections extend downwardly toward the transition piece and outwardly toward the barrel walls, and the lower fin sections extend downwardly and inwardly into the transition piece.
