摘要： In a method of operating a gas turbine, in which a gaseous fuel is burned in a combustion chamber and the hot combustion gases which are produced in the process are directed through the gas turbine, and in which method the gaseous fuel is fed to the combustion chamber via a plurality of controllable burners, working in parallel and arranged on one or more concentric, essentially circular rings, and is sprayed into the combustion chamber via fuel holes, high safety and availability within various operating ranges is achieved in a simple manner owing to the fact that the burners are divided into at least two groups (40-42) of burners, these groups in each case include the burners of one of the rings, and these groups are individually activated as a function of the operating state of the gas turbine.

摘要： A burner arrangement (20) for a gas turbine comprises an interior space (22) enclosed by a casing (23), in which interior space (22) at least one burner (21) is arranged, and into which interior space (22) in each case a jet (26, 27) of a gaseous medium, in particular air, is sprayed through at least two nozzle openings (24, 25) against the direction of flow of the burner (21) and along the inner wall (23a) of the casing (23) which jets (26, 27), guided by the inner wall (23a), meet one another from opposite directions and combine to form a secondary flow (28) flowing off perpendicularly from the inner wall (23a). In such a burner arrangement, the flow is stabilized and evened out by virtue of the fact that, to establish the impingement point of the jets (26, 27), a dividing plate (29) arranged in the flow path of the jets (26, 27) and disposed essentially perpendicularly to the inner wall (23a) is provided.

摘要： In a method for operating a premix burner a water quantity is introduced into at least one of the burner and the reaction zone of the burner depending on at least one command variable formed from at least one measured value. The method can also be used if a burner is operated dry, i.e., without water injection for nitrogen oxide injection, and the injected water quantity is less than 20% of the fuel quantity. The method can be used advantageously especially if a characteristic value derived from combustion pulsations or material temperatures is used as a command variable. The method enables measured parameters to be kept below a permissible upper limit.

摘要： A premix burner includes a swirler (7) for a combustion air stream and a device for injection of fuel into the combustion air stream. The swirler (7) includes one or more inlet openings for combustion air of the combustion air stream entering the burner. The device for injection of fuel into the combustion air stream includes one or more first fuel lines (8) with first fuel injection openings (4). The opening diameter and/or the injection angle of the injection openings varies with respect to the axial and/or radial direction. Alternatively or in addition, some of the first fuel injection openings (4) may be arranged in one or more first groups of closely grouped fuel injection openings (4) so that each of the first groups forms one fuel jet with a large cross section. An improved mixing of the fuel with the combustion air is achieved with the burner in particular in cases in which the fuel is injected at the end of the burner facing the combustion chamber.
