Beschreibung
Zusammenfassung:	The present invention pertains to a system for mixing a spray into a gaseous flow, comprising: a main body (100) defining an interior (101) extending from a first end (110) to a second end (120), having an inlet opening (140) and an outlet (150); a reaction zone (160) between the inlet opening (140) and the outlet (150), spaced from the first end (110) to define a mixing region (200); a restrictor arrangement (170) between the first end (110) and the reaction zone (160), separating the mixing region (200) into two chambers (210, 220) and defining a restricted passageway between the two chambers (210, 220). The first chamber (210) comprises: a dosing arrangement (180) to receive an injector to mix reactant with the gas in the first chamber (210); a first swirl promoting means (310) between the inlet opening (140) and the dosing arrangement (180); and a second swirl promoting means (320) between the dosing arrangement (180) and the restrictor arrangement (170), wherein said dosing arrangement (180) is adapted for receiving an injector such that an injection axis of said injector is directed to the first swirl promoting means (310).
