Abstract:
1. Cyclone separator for blast furnace gas comprising: a cyclone vessel having a central axis and including a side wall, a top wall and bottom wall; a first inlet duct connected with an end to said side wall of said cyclone vessel at a predetermined position intermediate the top and bottom wall; a second inlet duct connected with an end to said side wall of said cyclone vessel in circumferentially spaced relationship to the first inlet duct; the first and second inlet ducts being connected to each other by a distribution device, which has a connection with a conduit to feed the blast furnace gas from above the cyclone vessel; a central outlet duct which traverses through the top wall of the cyclone vessel and extends into said cyclone vessel; wherein the ends of said first and second inlet ducts in the vicinity of the side wall of the cyclone vessel are inclined in downward direction towards the side wall of the cyclone vessel between a minimum inlet angle α of 65° with the central axis of the cyclone vessel and a maximum inlet angle α of 85° with the central axis of the cyclone vessel.
