    摘要： 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.

    摘要： The method involves arranging compressor (1) with annular entry surface, two burners, combustion chambers (14,15) and high-pressure turbines (16,17). The oxygen-reduced gas (21) and sucking-in fresh air (2) are supplied alternately to the compressor. The oxygen concentration of the oxygen-reduced gas is smaller than the oxygen concentration of sucking-in fresh air of compressor. The flow channel of the compressor is attached with compressor intake (3) having two sections (51,52) arranged alternately in circumferential direction. An independent claim is included for gas turbine electric power plant.

    摘要： In a method for operating a gas turbine (11), NOx is removed from the exhaust gases of the gas turbine (11) by means of a selective catalysis device (14) with the addition of NH3. The method achieves an extremely low NOx content while simultaneously achieving economic consumption of NH3 and avoiding NH3 in the exhaust gas by maintaining the NOx content of the exhaust gas at a constant level via a regulated return of a portion of the exhaust gas in varying operating conditions of the gas turbine (11), and by adjusting the addition of the NH3 in the selective catalysis device (14) to the constant NOx level.

    摘要： The invention relates to a gas turbine plant (1), comprising a gas turbine device (2), which has a compressor (5) and at least one burner (6, 7) and at least one gas turbine (8, 9), a waste heat boiler assembly (3), which has a boiler inlet side (10) connected to a turbine outlet (12) and a first boiler outlet (13) connected to a flue (15) and a second boiler outlet (14), and an exhaust gas recirculation (4), which connects the second boiler outlet (14) to a compressor inlet (18). A simplified structure can be achieved in that the waste heat boiler assembly (3) has a first boiler exhaust gas path (20), which is connected to the boiler inlet side (10) and leads to the first boiler outlet (13), and that the waste heat boiler assembly (3) has a second boiler exhaust gas path (21), which is connected to the boiler inlet side (10) and leads to the second boiler outlet (14) separately from the first boiler exhaust gas path (20).
