1. A sequential combustor arrangement comprising a first burner, a first combustion chamber, a dilution burner for admixing a dilution gas and a second fuel via a dilution-gas-fuel-admixer to the first combustor combustion products leaving the first combustion chamber during operation, and a second combustion chamber arranged sequentially in a fluid flow connection, wherein dilution-gas-fuel-admixer has at least one streamlined body which is arranged in the dilution burner for introducing the at least one second fuel into the dilution burner through at least one fuel nozzle, and which has a streamlined cross-sectional profile and which extends with a longitudinal direction perpendicularly or at an inclination to a main flow direction prevailing in the dilution burner, where the streamlined body comprises a dilution gas opening for admixing dilution gas into the first combustor combustion products upstream of the at least one fuel nozzle. |
