Abstract: A vessel for containing direct reduced iron (DRI), such as a reactor for the production of DRI, a bin or a hopper or other container for storing or feeding DRI to melting furnaces or briquetting machines, includes at least an upper zone, defined by a first lateral wall having a substantially cylindrical tubular shape, and a discharge zone, positioned below the upper zone and defined by a second lateral wall having a substantially truncated cone shape converging toward a lower discharge aperture. The second lateral wall has an internal surface at least partly lined by an internal lining.

Abstract: A delivery device for delivering stock material into a blast furnace includes a transition channel for the stock material, a chute for delivering the stock material, a first annular body, coaxial to and outside the transition channel, adapted to rotate about a first axis, and a second annular body, coaxial to and outside the first annular body, adapted to translate along the first axis with respect to said first annular body and/or to rotate about the first axis together with said first annular body. When the second body translates along the first axis, at least one fixed rack rotates at least one toothed wheel and a respective shaft about a second axis transversal to the first axis, thus causing a change in the inclination of the chute with respect to the first axis.

Abstract: A direct reduction system for a direct reduction of iron ore, comprising a reactor having a reduction area and being adapted to be loaded from above with said iron ore; a treatment and feeding line, to process the process gases, thus obtaining a reducing gas mixture, and feed said reducing gas mixture into the reduction area; a line for recovering and treating an exhausted gas exiting the reactor, communicating upstream with the reactor and downstream with said treatment and feeding line; wherein at least one bypass duct is provided, adapted to divert at least one portion of reducing gas mixture from said treatment and feeding line to said recovery and treatment line.

Abstract: A sealing device for a vessel to achieve a fluid-tight seal in an aperture made in the lateral wall of said vessel, into which aperture a shaft is inserted. The sealing device comprises first sealing means disposed in contact with the shaft in the zone of said aperture, and second sealing means, comprising a containing body and a flexible connection element. The first sealing means comprise a plurality of sealing rings, disposed coaxial to the shaft and in contact with the latter, and a containing tube to contain the sealing rings. The lateral wall of the vessel comprises an interface flange. A closing flange is connected to the interface flange and to a flanged end of the containing body by means of attachment means and is positioned in contact with the containing tube and with the flexible connection element to keep the first sealing means in a determinate axial position with respect to the shaft.
