摘要： A shaft furnace bleeder valve for controlling a gas outflow from the interior of a pressurized furnace to the ambient atmosphere through an exhaust conduit is proposed. The bleeder valve comprises a valve seat associated with the exhaust conduit, a movable closure member having a central closure surface and a peripheral sealing surface cooperating with the valve seat, the closure surface comprising a convex surface at least in proximity to the sealing surface. The valve further has an actuating mechanism, which is connected to the closure member for moving the closure member between a closed position on the valve seat and an open position distant from the valve seat. According to the invention, the closure member comprises a recurved deflection portion at the periphery of the peripheral sealing surface, the recurved deflection portion comprising a deflection surface inclined against the convex surface by an angle in the range of 30° to 70° for imparting to a gas outflow passing between the valve seat and the closure member a velocity component which is opposite to the initial opening movement of the closure member.

摘要： The invention proposes an arrangement for burning blast furnace off-gas from a bleeder valve. It comprises a bleeder valve (20) having a fixed hollow valve body (22) defining an outlet (26) and a valve seat and a movable obturator (24) that cooperates with the valve seat for closing the bleeder valve and releasing blast furnace off-gas through the outlet. The arrangement includes an apparatus for combustion of blast furnace off-gas released by the bleeder valve (20). This apparatus is characterized by an ignition device (32, 38, 40, 42, 44) that is arranged on or adjacent the valve body or the moveable obturator of the bleeder valve (20) itself. The ignition device (32, 38, 40, 42, 44) has its spatial ignition range located downstream the outlet in a region where blast furnace off-gas released through the outlet mixes with ambient air when the obturator is in an open position so as to allow open-air combustion of blast furnace off-gas released into ambient air at the location of the bleeder valve.

摘要： The present invention proposes a method for feeding a burden to a blast furnace (32), wherein the method comprises providing a charging device (38) having at least one material hopper (40), the material hopper (40) comprising a hopper chamber (42), a material inlet aperture for feeding a burden into the hopper chamber (40), and a material discharge aperture for feeding a burden from the hopper chamber (40) to the blast furnace (32); the material inlet aperture having an associated inlet seal valve 44) for opening and closing the material inlet aperture and the material discharge aperture having an associated material discharge valve (46) for opening and closing the material discharge aperture. The method further comprises opening the material inlet aperture and closing the material discharge aperture; feeding a burden into the hopper chamber (40) through the material inlet aperture; closing the inlet seal valve (44); pressurizing the hopper chamber (40) by feeding pressurizing gas into the hopper chamber (40); and opening the material discharge valve (46) and feeding the burden from the hopper chamber (40) to the blast furnace (32). According to an important aspect of the invention, the method comprises feeding a predetermined amount of pressurized flushing gas through the hopper chamber (42) before pressurizing the hopper chamber (42), wherein the flushing gas comprises at least 75% carbon dioxide.

摘要： Annular swivel joint (300), especially for use in a shaft furnace charging device (10) that is equipped with a cooling system (12) with a stationary and a rotary circuit portion (30, 32). The annular swivel joint (300) comprises an annular fixed part (312) and an annular rotary part (310) and include an annular trough that defines an annular volume, via which the circuits portions (30, 32) communicate. The annular swivel joint (300) is characterized by: a stationary forward connection (302) for receiving cooling fluid from the stationary circuit portion (32); a rotary forward connection (304) for supplying cooling fluid to the rotary circuit portion (30); a rotary return connection (306) for receiving cooling fluid from the rotary circuit portion (30); and a stationary return connection (308) for returning cooling fluid to the stationary circuit portion (32); a partition (320) dividing the annular volume into an annular external cavity (322) and an annular internal cavity (324) so that the forward connections (302, 304) are coupled via one of the external and internal cavities (322 / 324) and the return connections (306, 308) are coupled via the other cavity (324 / 322), so that the internal cavity (324) is at least partially surrounded by the external cavity (322). The cavities (322, 324) are in double leakage-permitting communication between the external and internal cavities through annular first and second clearances (350, 352) provided to allow relative rotation between the fixed and rotary parts (310, 312); and annular flow restrictors (360, 362) provided in the first and second clearances (350, 352) respectively to reduce leakage between the cavities (322, 324).
