Abstract: A new method of improving cyclone separator, which was added the secondary flow at vortex finder. By controlling the size of sec ondary flow and entering wind’s direction changed the flow field of cy clone. The changed flow field would reduce the up ash loop and the short circuit to improve the separation efficiency of cyclone, especially im prove the cyclone’s ability of separate tiny dust.
