Abstract

Bei einem Brenner (10) zur Erzeugung eines Heissgases, welcher Brenner (10) mit einem von einer Austrittskante (16, 17) berandeten Brenneraustritt (22) in einen Brennraum (23) mündet, in welchem ein aus dem Brenneraustritt (22) unter Ausbildung einer Abströmgrenzschicht (18') ausströmendes Brennstoff-Luft-Gemisch nach dem Zünden des Brenners (10) eine Flamme (20) ausbildet, wird der Brennvorgang dadurch verbessert, dass zur Verhinderung von periodischen Wärmefreisetzungen und damit verbundenen thermoakustischen Schwingungen im Brennraum (23) am Brenneraustritt (22) Mittel (21) zur Aenderung der Dicke der Abströmgrenzschicht (18') angeordnet sind.

Figure 00000001
In the case of a burner (10) for generating a hot gas, the burner (10) with a burner outlet (22) bordered by an outlet edge (16, 17) opens into a combustion chamber (23) in which a burner outlet (22) is formed an outflow boundary layer (18 ') flowing fuel-air mixture forms a flame (20) after igniting the burner (10), the combustion process is improved in that to prevent periodic heat releases and associated thermoacoustic vibrations in the combustion chamber (23) Burner outlet (22) means (21) for changing the thickness of the outflow boundary layer (18 ') are arranged.
