Zusammenfassung:	Provided are a method and an arrangement 22 for supplying and mixing a reducing agent into a flue gas FG flowing through a gas duct 14 and into a selective catalytic reduction (SCR) reactor 18 arranged downstream of the arrangement 22. The subject arrangement 22 is useful in both high and low dust environments to mitigate ash and like particulate accumulation on reducing agent nozzles 42 and to provide more uniform reducing agent flow distribution upstream of the SCR reactor 18.
