FIELD: metallurgy.
SUBSTANCE: invention relates to metallurgy, in particular, to gas outlet channel of a steel making unit. Gas outlet channel includes at least one sleeve filter with a smoke exhauster, as well as dust-laden gas manifold, cleaned gas manifold and a flue gas gathering manifold, combining bag filters and smoke exhausters into a single system with common dust discharge system. Gas duct from steel-making unit is equipped with series-installed carbon oxide afterburning chamber, water-cooled gas duct, dust-collecting chamber and sucking control valve, electrically connected to a temperature sensor. At inlet pipes of dust-laden gas and outlet pipes of cleaned gas, connecting bag filters with dust-laden gas manifold and cleaned gas manifold, as well as on suction and discharge pipes of smoke exhausters there are cutoff valves.
EFFECT: higher reliability of gas outlet channel and efficiency of cleaning process gases.
