Abstract
A sequential combustor arrangement including a first burner, a first combustion chamber, a mixer for admixing dilution air to hot gases leaving the first combustion chamber during operation, a second burner, and a second combustion chamber arranged sequentially in a fluid flow direction. The mixer guides combustion gases in a hot gas flow path extending from the first combustion chamber. The second burner including a duct having an inlet for connection to the first combustion chamber and an outlet for connection to the second burner. The mixer includes injection pipes pointing inwards from the side walls for admixing the dilution air to cool the hot gases leaving the first combustion chamber. The injection pipes are distributed circumferentially along the side wall of the mixer. The injection pipes have a conical or quasi-conical shape addressed to the center of the mixer.
