摘要： A device for regulating the temperature of a gas in a hot gas main for feeding hot gas to a blast furnace includes a mixing pot with two mixing chambers in fluid communication with each other by means of a Venturi restriction. The first mixing chamber includes three inlet ports for feeding hot gas into the first mixing chamber, feeding cold gas into the first mixing chamber and feeding cold gas into the second mixing chamber, respectively. The first mixing chamber further includes an outlet port for feeding a first stream of mixed gas from the first mixing chamber to a first gas distribution system. The second mixing chamber includes a second outlet port for feeding a second stream of mixed gas from the second mixing chamber to a second gas distribution system. The first and second streams of mixed gas have different temperatures.

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.
