In a combustion chamber (100) which is designed as an annular combustion chamber and a mixing essentially comprises a primary zone (1), a mixing section (2) arranged downstream and an adjoining secondary stage (3), vortex generators (200) are fixed inside the mixing section (2), which vortex generators (200) serve to form vortices. Both the mixing section (2) and the vortex generators (200) are provided with passage openings through which mixing air (8) flows into the interior of the mixing section (2) and mixes there with the main flow (4). The quantity of the intermixed mixing air (8) is variable; it can have a supercritical or subcritical blow-out rate relative to the main flow (4), and in this connection at least film cooling of the duct walls (5, 6) and of the vortex generators (200) takes place even at subcritical blow-out rate. If a supercritical blow-out rate is taken as a basis, the mixing air (8) penetrates the marginal zones of the vortices induced by the vortex generators (200), which leads to rapid mixing of this mixing air (8) with the main flow (4).
