    Abstract: An injector mixer arrangement (10) for supplying a reducing agent in gaseous form into a flue gas flowing in a gas duct (14) communicating with a catalyst (18a) in a selective catalytic reduction (SCR) reactor (12) arranged downstream of said injector mixer arrangement (10). The injector mixer arrangement (10) comprises an injector grid (22) equipped with a plurality of nozzles (30) arranged horizontally within the gas duct (14). The nozzles (30) are adapted to supply said reducing agent to the gas duct (14). The injector mixer arrangement (10) further comprises first stage mixer plates (24) and second stage mixer plates (26) arranged in the gas duct (14) downstream of said nozzles (30) and upstream of SCR reactor 12.

    Abstract: The invention pertains to fluegas recirculation in gas turbines, and specifically to an intake section upstream of the inlet of a compressor of a gas turbine unit with fluegas recirculation. The intake section includes at least one section with a flow path defined by sidewalls in which the fresh airflow of the intake air is flowing along a principal airflow direction, including at least one mixing duct extending into the flow path from at least one sidewall. The mixing duct includes an intake at the at least one sidewall for receiving recirculated fluegas, as well as including at least one outlet opening distanced from said sidewall for blowing recirculated fluegas out of the mixing duct into the airflow.
