Abstract
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.
