摘要： The present invention proposes a bustle pipe arrangement (10) of a shaft furnace, in particular for feeding hot gas into the shaft furnace such as e.g. a blast furnace, wherein the bustle pipe arrangement (10) comprises a circumferential bustle pipe (12) arranged along the outer casing (14) of the shaft furnace, at a certain distance therefrom. The arrangement (10) further comprises a plurality of first support arms (22) connecting the bustle pipe (12) to the outer casing (14) of the shaft furnace; and a plurality of second support arms (24) connecting the bustle pipe (12) to the outer casing (14) of the shaft furnace. The first and second support arms (22, 24) are configured to support the circumferential bustle pipe (12). First blow channels (26) are arranged through the first support arms (22) for fluidly connecting the bustle pipe (12) to the interior of the shaft furnace.

摘要： In a blast furnace plant (10), at least three regenerative heaters (14.1, 14.2, 14.3) are cyclically operated on blast and on gas: while a regenerative heater is operated on gas, hot flue gas is produced and caused to flow through the regenerative heater so as to heat the heat storage elements (46); and while a regenerative heater is operated on blast, process gas (32), i.e. a CO-rich fraction of the top gas (16), is blown through the regenerative heater so that the process gas takes up heat from the heat storage elements. During a changeover of a regenerative heater from on-blast to on-gas operation, the regenerative heater is purged from process gas using flue gas collected after having flown through at least one of the regenerative heaters.

摘要： The present invention proposes a device (10) for regulating the temperature of a gas in a hot gas main for feeding hot gas to a blast furnace. Such a device (10) comprises a mixing pot (14) with a first mixing chamber (16) and a second mixing chamber (18), the first and second mixing chambers (16, 18) being in fluid communication with each other by means of a Venturi-type restriction (20). The first mixing chamber (16) is provided with a first inlet port (22) for feeding hot gas into the first mixing chamber (16), a second inlet port (26) for feeding cold gas into the first mixing chamber (16) and a third inlet port (56) for feeding cold gas into the second mixing chamber (18). The first mixing chamber (16) is further provided with a first outlet port (42) for feeding a first stream of mixed gas from the first mixing chamber (16) to a first gas distribution system (46), while the second mixing chamber (18) is provided with a second outlet port (60) for feeding a second stream of mixed gas from the second mixing chamber (18) to a second gas distribution system (64). The first stream of mixed gas has a temperature different from a temperature of the second stream of mixed gas.

摘要： The present invention proposes a method for operating a blast furnace (12) comprising the steps of recovering top gas from the blast furnace (12); submitting at least a portion of the top gas to a recycling process; and feeding the recycled top gas back into the blast furnace (12). According to an important aspect of the invention, the recycling process comprises feeding the recovered top gas to a reformer unit (40); feeding volatile carbon containing material (42) to the reformer unit (40); proceeding to flash gasification of the volatile carbon containing material in the reformer unit (40), at a temperature between 1100 and 1300°C, and thereby producing devolatised carbonaceous material and synthesis gas; and allowing the devolatised carbonaceous material and synthesis gas to react with the recovered top gas. The invention also proposes a blast furnace installation (1) with a blast furnace (12) and a top gas recycling installation (14) for carrying out the above method.

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.
