    摘要: In a burner for operating a combustor, the former consists essentially of a rotation generator (100), a transition piece following the rotation generator, and a mixing pipe following this transition piece. Transition piece and mixing pipe form the mixing section (220) of the burner and are located upstream from a combustion chamber (30). In the lower part of the mixing pipe is located a pilot burner system (300) which creates, among other things, a stabilization of the flame front, in particular in the transient load ranges, while minimizing pollutant emissions. A sensor (400) installed in the burner detects a flashback of the flame (80), whereupon the fuel quantity of this flame is at least temporarily reduced and at the same time the fuel quantity for the pilot burner is increased in such a way that the total fuel quantity and thus the turbine output remains constant. This measure prevents a destruction of the burner.

    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).

In the region of the tangential combustion-air-directing inflow ducts (101b-104b), fuel-directing ducts (121-124), the cross section of flow of which is designed for a low-calorific fuel (116), extend along the swirl generator (100). The fuel-directing ducts (121-124) end at a distance upstream of the transition of the tangential inflow ducts (101b-104b) into an interior space of the swirl generator (100), whereby partial mixing between the two media (115, 117) takes place before the mixture flows into the interior space (118). In addition, this setting-back provides sufficient space for other fuel-directing lines (111-114) in this region.
