摘要:
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.
