Abstract (en)
[origin: EP0987491A1] Disturbance air (22) is injected into the combustion air flow (15) in order to prevent the formation of coherent flow instabilities of the combustion air flow after outlet in the combustion chamber (28). The burner (26) has no premixing stretches and is operated with liquid or gaseous fuel.
