Beschreibung
Zusammenfassung:	A method and apparatus for mixing at least one fluid stream with a large gas stream flowing in a gas duct, especially for introducing reducing agent into flue gas containing nitrogen oxides. The gas stream is directed against at least one disk-shaped mixer element on an inlet side that is inclined at an angle counter to the direction of flow of the gas stream, wherein eddy-type whirls form at the mixer element. A swirled fluid stream is admixed with the large gas stream downstream of the mixer element.
