Beschreibung
Zusammenfassung:	A gas turbine combustion chamber (10), having a combustion chamber housing (11), having a burner (12) that is positioned in the combustion chamber housing (11) at least in portions, having a flame tube (15) positioned in the combustion chamber housing (11), which contains a primary combustion zone (16) of the gas turbine combustion chamber (10), wherein on an upstream end of the flame tube (15) a flame tube cover (17) is positioned, wherein in the region of the flame tube cover (17) radially inside adjoining the flame tube cover (17) a mixing tube (19) of the burner (12) extends, which at least in portions defines a pre-primary combustion zone (21) of the gas turbine combustion chamber (10), wherein between the mixing tube (19) of the burner (12) and the flame tube cover (17) an axial airflow passage (20) is formed, via which for cooling the mixing tube (19) air can be conducted in the axial direction outside along the mixing tube (19), and wherein into the flame tube cover (17) radial air flow passages (22) are introduced via which the air following the axial air flow passage (20) can be conducted in the radial direction of the flame tube cover (17) for cooling the flame tube cover (17).
