<p>The method involves providing a burner (1) with a burner axis (4) and a jet nozzle (2), which is provided with a central axis (5), a jet nozzle outlet (9) and a wall (7) that runs in a radial direction starting from the central axis and faces the burner axis. A volumetric fluid flow is allowed to flow through the jet nozzle to the jet nozzle outlet. An air film (20) is formed at the jet nozzle outlet between the volumetric fluid flow and the wall by air that is injected into the jet nozzle along the wall. An independent claim is also included for a burner including a burner axis and a jet nozzle.</p> |
