In a burner which essentially comprises a swirl generator (100) for a combustion-air flow (115) and means for injecting a fuel into the combustion-air flow (115), a mixing section (220) is arranged downstream of the abovementioned swirl generator. This mixing section (220) has inside a first part (200) of the section a number of transition passages (201) which run in the direction of flow and ensure the smooth passing of the flow (40) formed in the swirl generator (100) into a tube (20) arranged downstream. The outlet plane of this tube (20) to the combustion chamber (30) is formed with a breakaway edge which serves to stabilize and enlarge a backflow zone (50) forming downstream.
ans un brûleur qui comprend essentiellement un générateur de rotation (100) pour un écoulement d'air de combustion (115) et un dispositif pour injecter un combustible dans l'écoulement d'air de combustion (115), une chambre de carburation (220) est installée en-dessous du générateur de rotation. La chambre de carburation (220) est formée d'une première partie (200) comportant plusieurs passages de transition (201) qui suivent la direction de l'écoulement et permettent le passage facile de l'écoulement (40), formé dans le générateur de rotation (100), vers un tube (20) installé en aval. ~ la sortie de ce tube (20) vers la chambre de combustion (30), la paroi s'élargit ce qui permet de stabiliser et d'agrandir une zone de refoulement (50) qui se forme en aval.
