Definitions
- the invention relates to a burner arrangement with Mischkanä ⁇ len, in which Ver Whyrendluft and fuel are pre-mixed before they are injected as a fuel-air mixture in a combustion chamber.
- WO 2015/176908 AI discloses such a burner arrangement which comprises a nozzle carrier with a hot side facing a combustion zone during operation and an opposite cold side facing away from the combustion zone, wherein passages in the nozzle carrier from the cold side to the hot side, ie parallel to the main axis the burner assembly horrre ⁇ ck, each with an inlet on the cold side and an outlet on the hot side.
- the passages serve as Strahldü ⁇ sen, which are arranged on one or more circles, for example in two fuel groups, each with a group on a circle, and fuel lances are arranged at the inlets.
- the two jet burner stages formed by the fuel groups are each substantially uniform in circumference with respect to the flame temperature because the fuel is evenly distributed. Only comparatively slight differences in air distribution result in comparatively low different flame temperatures.
- the object of the invention is therefore to provide a burner assembly of the type mentioned, which has an improved behavior with respect to high-frequency vibrations.
- the invention solves the addressed to a burner assembly object by providing that, in such a Bren ⁇ neran extract extending with several parallel to the main axis of the burner assembly and arranged on at least two concentric rings mixing channels in which during operation of the burner assembly of fuel and
- Compressor air are mixed, the mixing channels are summarized in fuel ⁇ fuel levels, wherein a fuel stage mixing channels with common fuel supply, which are jointly controlled in operation, and wherein a, based on the geometric distribution of the respective fuel stages associated mixing channels, irregular Stu ⁇ tion in the circumferential direction of the burner assembly results.
- the invention thus provides a primasstufung for the burner arrangement instead of the radial in the art of ⁇ fenbarten graduation.
- Staging is carried out so that they on the circumference no Re ⁇ gel marching the type AABB (A and B are nozzles or groups of nozzles with common fuel supply).
- a and B are nozzles or groups of nozzles with common fuel supply.
- the proposed grading also allows for more stable operation of the burner assembly against flame loss during loading.
- the burner assembly comprises a centrally disposed pilot burner to the combustion of the ⁇ bilize provided by the mixing ducts fuel-air mixture to sta.
- a fuel stage consists of at least two subgroups, which in turn consist of at least two immediately adjacent mixing channels of different rings. The formation of subgroups stabilizes the flames of the respective ones
- a number of mixing channels of a ring is twice as high within a Untergrup ⁇ pe no more than, like a number of mixing channels of another ring. This ensures that a ratio of the number of mixing channels of the individual subgroups over the entire burner arrangement is usefully distributed in order to ensure the highest possible combustion stability over all.
- the subgroups a distinct An ⁇ number of mixed channels. This asymmetry helps to prevent high-frequency combustion oscillations.
- the number of Mischkanä ⁇ le a fuel stage does not exceed more than 50%, data of the entire burner arrangement, the load of subsequent components due to adjustments of the fuel allocation to the individual fuel stages to avoid of combustion vibrations can be kept as small as possible.
- FIG. 1 shows schematically and not to scale a burner assembly 1 with a plurality of parallel to the main axis 2 of the burner assembly 1 extending and arranged on two concentric rings 3 mixing channels 4, in which during operation of the burner assembly 1 fuel and
- the mixing channels 4 are summarized in fuel stages 5, which are marked in the figure with A and B, that results in an irregular gradation in the circumferential direction 6 of the burner assembly 1.
- the figure shows only an example, but the principle of a fuel staging over the circumference can be transferred to any number of mixing channels 4 and it is irrelevant whether it is an even or odd number of mixing channels 4. Also, the number of rings 3, on which the mixing channels 4 are arranged, may vary.
- the burner assembly 1 can also have more than two premixed fuel stages 5 (A and B), but this is not sensible due to cost considerations.
- the mixing ⁇ channels 4 of the fuel stages 5, which are designated A and B, are distributed unevenly over the circumference.
- bil ⁇ always at least two adjacent mixing channels 4 from the inner and the outer ring 3, a sub-group 8 of the
- a fuel level 5 may be made of two, three or more sub-groups ⁇ 8 with different numbers of mixing ducts 4 sawn In the example of the figure, there are two subgroups 8 per fuel level 5.
