In an arrangement for mixing a first gas into a main flow of a second gas, comprising a main conduit for said main flow and a plurality of supply conduits for the first gas which open into said main conduit, the supply conduits are arranged as at least one set of three outlet openings. This set consists of a first opening which opens into the main flow perpendicularly to the main conduit wall and two second openings which are arranged so as each to provide a lesser flow rate of the first gas than the first opening and are offset with respect to the first opening. The three openings of the set thus direct the first gas into two contra-rotating circulatory movements, as viewed in the direction of the axis of the main conduit. This mixing arrangement is applicable for example to mixing a hot gas into the gas obtained from an ore pellet drying bed and to mixing a hot gas into a water-laden gas from a desulphurization plant.
