摘要： The invention pertains a power plant (1) comprising a gas turbine (2), a heat recovery boiler arrangement (3) with at least a boiler inlet (10), and an outlet side with a first exit (13) connected to a stack (15) and a second exit (14) connected to a flue gas recirculation (4), which connects the second exit (14) to the compressor inlet (18) of the gas turbine (2). The heat recovery boiler arrangement (3) comprises a first boiler flue gas path (20) from the boiler inlet (10) to the first boiler exit (13), and a separate second boiler flue gas path (21) from the boiler inlet (10) to the second boiler exit (14). Additionally, a supplementary firing (49) and a subsequent catalytic NOx converter (50) are arranged in the first boiler flue gas path (20). Besides the power plant (1) a method to operate such a power plant (1) is an object of the invention.
