摘要： An apparatus (20) for insertion and extraction of a fuel injection lance (10) into and out of a tuyere stock (1) of a shaft furnace, in particular of a blast furnace, is proposed. The tuyere stock (1) comprises a lance sheath (12) that defines an insertion/extraction axis (49) and is mounted in coaxial extension of a lance channel through which an injection lance can be inserted into the tuyere stock. The proposed apparatus comprises a linear guide (22), a carriage (24) and a mounting support (50). The carriage is movably supported by the linear guide and cooperates with a connecting device (42) for connecting an injection lance to the carriage such that the injection lance can be moved axially along a translation axis by the carriage. The linear guide comprises a mechanism (36; 38) for linearly moving the carriage along a guide axis (35) and a first coupling half (64; 65; 66) for mounting the linear guide (22) to the mounting support attached to the tuyere stock. The mounting support (50) has a second coupling half (57; 58; 62) cooperating with the first coupling half (64; 65; 66) of the linear guide for removably attaching the linear guide to the tuyere stock. The mounting support (50) and the coupling halves (57; 58; 62; 64; 65; 66) orient an attached linear guide (22) so that the guide axis (35) of the linear guide in parallel to the insertion/extraction axis (49) and so that the translation axis of an injection lance (10) connected to the carriage (24) is coaxial with the insertion/extraction axis (49).

摘要： The invention relates to a pneumatic delivery device comprising a pneumatic delivery pipe (12, 14) into which a heat exchanger is integrated. Said heat exchanger (10) has a cylindrical outer housing (16) with a first end (18) and a second end (20), an inlet port (26) for a flow of pneumatic medium on its first end (18) and an outlet port (28) for the flow of pneumatic medium on its second end (20). A housing core (32) is disposed inside the cylindrical outer housing (16) in such a manner as to define an annular flow gap (34) for the flow of pneumatic medium. Inside said annular flow gap (34), a first spiral tube (36) is disposed though which a heat transfer medium flows.

摘要： The preliminary cleaning stage of a dust extraction installation for blast furnace gas consists of a large-size cyclone (10) which comprises a vertical pressurized tank (14). A blast furnace gas line (12) arriving from the blast furnace is connected to an axial delivery device (34, 26, 28, 50) situated at the upper end of the pressurized tank (14). The delivery device (34, 26, 28, 50) is configured such that it introduces the blast furnace gas into the pressurized tank (14) in an axial direction. A swirl device (58) with guide vanes (66) is positioned below the axial delivery device (34, 26, 28, 50) and causes the blast furnace gas which is axially introduced into the pressurized tank (14) to swirl about the axis (30) of said pressurized tank (14).

摘要： A device for continuously feeding a powdery solid out of a storage bin (10) and into a pneumatic conveying line (12, 12') comprises a first and a second intermediate vessel (14 and 16) that are placed adjacent to one another. The first intermediate vessel (14) is provided in the form of a sluice vessel having an upper sluice gate (18) and a lower sluice gate (20). The second intermediate vessel (16) is provided in the form of an injection vessel. A pneumatic intermediate conveyance (50) is placed between the lower sluice gate (20) of the first intermediate vessel (14) and an upper inlet (30) of the second intermediate vessel (16). This intermediate conveyance enables the powdery solid to be conveyed out of the first intermediate vessel (14) and into the second intermediate vessel (16).

摘要： Tuyere stock arrangement (10) of a blast furnace comprising a tuyere (14) having a tuyere body (20) configured for installation in a blast furnace wall (12); the tuyere body (20) having an outer wall (22), a front face (24) and a rear face (26), the tuyere body (20) further having a tuyere channel (28) extending from the rear face (26) to the front face (24), the tuyere channel (28) forming an inner wall (30) in the tuyere body (20). The tuyere stock arrangement (10) further comprises a blowpipe (34) connected between the rear face (26) of the tuyere body (20) and a gas feeding device (38), the blowpipe (34) being configured and arranged so as to feed hot gas, generally hot blast air, from the gas feeding device (38) to the tuyere channel (28) for injection into the blast furnace. The tuyere stock arrangement (10) also comprises an injection lance (40) for feeding a combustible, generally pulverized or granular coal, into the blast furnace at the tuyere level, the injection lance (40) being an coaxial lance comprising an outer pipe and an inner pipe, coaxially arranged within the outer pipe, the outer and inner pipes being arranged for separately conveying oxidizing gas and said combustible, the inner pipe forming a separation wall for separating said combustible from the oxidizing gas. According to an important aspect of the invention, the injection lance (40) is removably arranged in a lance passage (42) formed in the tuyere body (20), the lance passage (42) being arranged between the inner wall (30) and the outer wall (22) of the tuyere body (20) and extending from the rear face (26) to the front face (24), the lance passage (42) opening into a front lace (24) of the tuyere body (20).
