Beschreibung
Zusammenfassung:	The invention refers to a sequential combustor arrangement (104) comprising a first burner (112), a first combustion chamber (101), a mixer (117) for admixing a dilution gas to the hot gases leaving the first combustion chamber (101) during operation, a second burner (113), and a second combustion chamber (102) arranged sequentially in a fluid flow connection. The mixer (117) comprises of injection tubes (114, 115) pointing inwards from the side walls (119) of the mixer (117) for admixing the dilution gas to cool the hot flue gases leaving the first combustion chamber (101). A flow guide (114, 115b) is arranged in the connecting duct (111) and/or the injection tubes (115, 115a) for guiding the dilution gas (110) into the injection tubes (115, 115a). The disclosure further refers to a gas turbine (100) and a method for operating a gas turbine (100) with such a sequential combustor arrangement (104).
