Abstract
In a burner for a heat generator, which consists essentially of a swirl generator (100a) for a combustion air stream (115) and of means for injecting a fuel into this combustion air stream, a mixing stage (220) is arranged downstream of said swirl generator. This mixing stage has, within a first stage part (200), a number of transition channels (201) running in the direction of flow, which ensure the continuous transfer of the flow (40), formed in the swirl generator (100a), into a tube (20) located downstream. A nozzle (103), arranged on the head side and on the burner axis (60), for the injection of a fuel is offset upstream at a distance relative to the start of the swirl generator.
