Abstract
A flow duct conducts a gaseous second fluid medium in a given flow direction and has a given cross-sectional area and a given hydraulic diameter. A combined feed and mixing device for introducing a first fluid medium into the second fluid medium in the flow duct and for mixing the fluid media includes at least one tube conducting the first fluid medium and having from 0.05 to 10 feed orifices per m.sup.2 of the given cross-sectional area. A mixing insert disposed downstream of the at least one feed orifice in the given flow direction is spaced apart from the feed orifices by a distance of from 0.05 to 3 times the given hydraulic diameter. The mixing insert has mixing elements being small relative to the given hydraulic diameter and being disposed in mutually parallel rows in a plane oriented at an angle to the given flow direction. The mixing elements of each of the rows are inclined relative to a plane in the same direction to one another and in opposite direction to the mixing elements of each adjacent row.
