摘要： In a burner which consists of a swirl generator (100) on the oncoming-flow side, the flow (40) formed herein is passed smoothly into a mixing section (220). This is done with the aid of a transition geometry which is present at the start of the mixing tube (220) and consists of transition passages (201) which cover sectors of the end face of the mixing section (220), in accordance with the number of sectional bodies of the swirl generator (100), and run helically in the direction of flow. On the outflow side of these transition passages (201), prefilming bores (21) pass through the mixing section (220), which prefilming bores (21) initiate an increase in the flow velocity along the tube wall. Adjoining the mixing section (220) is a combustion chamber (30) in which a backflow zone (50) forms in the region of the jump in cross-section between mixing section (220) and combustion chamber (30).

摘要： The invention relates to a premix burner with high flame stability for use in a heat generator, preferably in the combustion chamber of a gas turbine. Modern, lean-operated premix burners enable very low noxious emissions, but sometimes operate very close to the extinction limit. To increase the stability of the lean premix combustion by increasing the distance between flame temperature and extinction limit temperature the invention proposes to equip the burner in the mixing zone (200) with a net-like structure (201) for the premixing of combustion air and fuel. According to a preferred embodiment, the net-like structure (201) consists of a plurality of layers of individual wire mesh fabrics (202) arranged at a distance from each other. The wire mesh fabrics (202) are preferably equipped with an oxidation-promoting, catalytically active surface. It was found that the net structure (201) positively influences the thermoacoustic behavior of the burner and dampens and insulates pressure waves from the combustion chamber (300), and in this way reduces the excitation of pressure waves in the combustion chamber (300).
