Zusammenfassung:	The invention relates to an arrangement for supplying a reducing agent in gaseous form into a flue gas flowing in a gas duct (4) communicating with a catalyst in a selective catalytic reduction reactor (SCR) arranged downstream said arrangement. The arrangement comprises a plurality of nozzles (21) arranged in the gas duct (4). The nozzles (21) are adapted to supply said reducing agent. The arrangement further comprises a plurality of mixing plates (30) arranged in the gas duct (4) downstream of said nozzles (21). Each mixing plate (30) is adapted to cooperate with at least one dedicated nozzle (21). Further, each nozzle (21) is arranged within a projected area of its dedicated mixing plate (30), the projected area is the area of a surface of the dedicated mixing plate (30) as projected in a plane perpendicular to the gas flow direction (F) of the gas duct (4).
