ABSTRACT:
In a burner (1) for heat generation, the inflowing air (4) is first of all directed into a hollow conical swirl generator (3) which is surrounded by a mixing tube (2). This swirl generator (3) tapers in the direction of flow in such a way that a hollow cone results therefrom. Furthermore, the swirl generator (3) has tangential openings (6, 7) in the direction of flow, which are preferably designed as ducts through which the combustion air (5) flows out of the hollow space (16) into the mixing tube (2). In the region of the tangential openings (6, 7), nozzles (12, 13) are provided through which a fuel (14) is injected into the combustion air (5) flowing past there. A fuel, whether liquid or gaseous, may be supplied by further means in operative connection with the burner (1).
