Abstract
This burner arrangement has a main feed channel (2) for a fuel-air mixture, which channel discharges into a combustion chamber (1). A swirler, which is provided with swirl vanes (5), is penetrated by a burner lance (3), and into which exit openings for the fuel feed discharge, is provided in this main feed channel (2). The aim is to create a burner arrangement in which it is impossible for undesired instances of ignition of the fuel-air mixture to occur outside the combustion chamber (1). This is achieved in that the exit openings are constructed as nozzles (9) which discharge into a region between the swirl vanes (5). In this regard, at least one nozzle is provided between two neighboring swirl vanes (5).
