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.
