The present invention relates to a method and devices for mixing at least two individual streams having different variables. In order to produce a low-loss, effective mixing within a short flow section, at least one eddy impulse is produced in the cross section of flow of at least one individual stream, which impulse spreads out downstream transverse to the direction of flow to form a discrete eddy system whose components transverse to the main direction of flow overlap into the other flow cross section of the other individual stream. This eddy impulse can be produced either by at least one curved surface or by at least one edge of a surface or of a body. The eddy impulse is preferably produced by two burble (flow break-away) edges of a delta-shaped insert element which extend at an acute angle to each other.

In a device for mixing at least two individual gas flow streams, the individual streams each defining a flow cross-section and a main direction of flow and discharging into each other via at least one discharge mouth, and at least one embodiment arranged in the flow cross section of a corresponding of the individual streams, the improvement wherein the element is a substantially, delta-shaped flat plate having planar surfaces and a sharp and free upstream V-shaped edge defining an upstream vertex and two portions of said edge on respective sides of said vertex, each of said two portions defining a sharp edge in cross-section, said surfaces of said plate being oriented inclined at a relatively small acute angle relative to said main direction of flow of the corresponding individual stream, said two portions of said edge extending transversely inclined to said main direction to flow of the corresponding individual stream, wherein said two portions of said edge producing therefrom within the flow cross section of said corresponding individual stream two continuous vortex momentums respectively initiating two conically widening oppositely rotating vortexes from each of said two portions of the edge, respectively, the vortexes travelling from the respective portions downstream and inclined relative to said main direction of flow while widening conically including transversely to the main direction of flow of said corresponding individual stream, extending into the flow cross section of at least one other of the individual streams, and effecting, substantially exclusively via said vortexes, mixing of said corresponding individual stream with said other of the individual streams.
