摘要： Disclosed is a premix burner, e.g. for a gas turbine, comprising a vortex generator (1), a cylindrical mixing section (2) that is located downstream thereof in the direction of flow, and a high-pressure spray nozzle (10) which is provided with one or several fuel supply ducts. The high-pressure spray nozzle (10) is equipped with at least two discharge ducts through which liquid fuel penetrates into the vortex generator (1). The ducts are disposed in a decentralized manner relative to the longitudinal axis of the nozzle while being configured such that the spray cone (11) of the fuel is oriented at an angle (ß) relative to the longitudinal axis of the vortex generator (1) which is smaller than the cone half-angle (a) of the vortex generator (1). The discharge ports are provided especially with an inner geometry that encompasses a conical constriction.

摘要： The invention relates to a method for reducing NOx emissions from a burner assembly (10), comprising several burners (B1,..,Bn), in particular, in a gas turbine. Said burners (B1,..,Bn) are operated in parallel and burn the respectively supplied fuel by means of combustion air to form a flame (F1,..,Fn). An aim of the invention is to obtain an effective reduction in a simple manner. Said aim is achieved, whereby the flame temperatures of individual burners (B1,..,Bn) or burner groups, or differences between the flame temperatures of individual burners (B1,..,Bn) or burner groups are directly or indirectly measured at a given time, and the fuel supply to the burners or burner groups, the flame temperature of which exceeds a preset value of the flame temperature, is selectively throttled in order to unify the flame temperatures of said burners (B1,..,Bn).

摘要： The invention relates to a premix burner for producing an ignitable fuel/air mixture, comprising a swirl generator, which provides at least two burner shells (1) that complete one another to form a flow body. These burner shells, together, enclose a swirl space that conically enlarges in an axial manner and, in an axial longitudinal extension of the cone, delimit mutually tangential air entry slits (3) via which the combustion supply air arrives in the swirl space, inside of which an axially expanding swirling flow is formed. The premix burner also comprises means (6) for injecting fuel that are provided, at least in areas, along the tangentially running air inlet slits (3). The invention is characterized in that: the means for injecting fuel is provided in the form of a fuel line (6), which is separate from the fuel shell (1), can longitudinally move relative to the burner shell (1), and which is detachably joined in a fixed manner to the burner shell (1) while being perpendicular to the surface of the burner shell (1), and; openings (4) are provided in the burner shell (1), into which fuel injectors (7) lead that are provided along the fuel line (6) and project beyond the peripheral edge of the fuel line (6).

摘要： The invention relates to a premixing burner arrangement for operating a burner chamber with a gaseous and/or liquid fuel. Said premix burner comprises a swirl generator (2) for a combustion air influx for forming a swirl and means (5) for jetting in fuel into the swirl. The swirl generator (2) comprises at least two partial conical shells (1) that complement each other to give a flow-type body and that together include a conical swirl chamber having a cone angle η and air inlet slots (4) that are tangential relative to the longitudinal extension of the cone. The invention is characterized in that at least in the flow-distal end zone of the swirl generator (2) a shaped element (7) enclosing the partial conical shells (1) and having an inner wall (6) facing the partial conical shells (1) is provided and in that the partial conical shells (1) run flush into the inner wall (6) thereby keeping the shape of the structure.

摘要： The invention relates to a combustion chamber (3) of a combustion installation, the combustion chamber (3) having a heat shield (1) with at least two segments (2) and (2'). Each of the segments (2) and (2') has a liner element (4, 4') facing a combustion space (3) and a holding device (5, 5'), with the liner element (4) attached to a supporting structure (7) via a supporting element (6). This attachment is effected by means of a border region (8) which is formed on the liner element (4) and engages behind a flange region (9) formed by the holding device (5). To cool the border regions (8), facing a gap (10) arranged between the edges of two adjacent liner elements (4) and (4'), of the liner elements (4), the holding device (5), in the region of its flange region (9), has through-openings (12), through which cooling gas flows out of a first cooling channel (11), which is formed by the holding device (5) together with the supporting element (6), onto the border region (8) which is to be cooled.
