Definitions
- the invention relates to a burner according to the preamble of claims 1 and 2.
- Such combustion instabilities can be suppressed actively, for example by increasing the power of the pilot flame, or passively, for example by resonators.
- FIG. 2 shows an enlarged detail from FIG. 1,
- FIG. 3 shows a swirl vane for a burner designed according to the invention
- FIG. 4 shows a swirl vane for a burner designed according to the invention
- Figure 5 velocity vectors of a flowing fuel air-gas mixture
- FIG. 1 shows a burner 1, in particular a premix burner 1, in particular for a gas turbine.
- the burner 1 has a burner longitudinal axis 46.
- a diffusion or pilot burner 43 is arranged centrally along the longitudinal axis 46 of the burner. In the premix mode, the pilot burner 43 is operated to support the burner 1.
- fuel 7 and / or air 4 is fed to a premixing section 10 and / or a combustion chamber 19 via a channel 13 (FIG. 6) that is annular, for example, to the longitudinal axis 46.
- a channel 13 annular, for example, to the longitudinal axis 46.
- oxygen or another gas can also be supplied, which together with fuel 7 results in a combustible fuel-gas mixture.
- air 4 is first supplied to channel 13 and then fuel 7.
- the air 4 flows in the channel 13, for example, at least on one
- the swirl blades 16 are arranged, for example, in a ring shape, in particular equidistantly, around the longitudinal axis 46 of the burner (FIG. 6).
- the air 4 and the fuel 7 mix in the premixing section 10, which is indicated by dashed lines.
- FIG. 2 shows the radial end 49 of the diffusion / pilot burner 43 with the annular channel 13.
- the fuel 7 is fed to the channel 13 via at least two fuel nozzles 31 and flows there in a flow direction 88.
- the fuel is preferably supplied via fuel nozzles 31 which are arranged in the swirl vane 16.
- the fuel 7 can also be supplied to the channel 13 via other distribution units.
- the combustion instabilities result from a distribution of the fuel concentration 58 according to the prior art.
- the concentration of the fuel is approximately the same.
- the operating range for burner 1 can thus be expanded.
- the fuel concentration changes, for example, in a radial direction
- Fuel concentration for example, linearly from or to.
- FIG. 3 shows a swirl vane 16 with which this can be achieved.
- the operating range can also be expanded if a discharge angle ⁇ of a medium, ie the angle between the resulting speed and peripheral speed (FIG. 5), for example the air / fuel / 7 mixture, has a distribution similar to the concentration of the fuel 7 has, ie seen from the burner longitudinal axis 46, the outflow angle ⁇ decreases, for example, in a radial direction 55 from a maximum value to a minimum value or vice versa. This is done, for example, by twisting the swirl blade 16 as described in FIG. 4.
- the outflow angle ⁇ is also the angle between the flow direction of the medium flowing in the channel (air, oxygen, fuel, mixtures thereof) and a plane whose normal is the burner longitudinal axis 46.
- the distribution 52 of the fuel concentration and the outflow angle ⁇ can also be combined with one another in order to expand and improve the operating range of the burner 1.
- FIG. 3 shows a swirl vane 16 for a burner 1 according to the invention.
- the swirl vane 16 has a leading edge 67 and a trailing edge 70.
- the medium flows in in channel 13
- Flow direction 88 first past the leading edge 67 and then past the trailing edge 70.
- FIG. 4 shows a further swirl vane 16 for a burner 1 according to the invention.
- the swirl vane 16 is designed, for example, with respect to the size and distribution of the fuel nozzles 31, like the swirl vane in FIG. 3.
- the airfoil 61 can still be wound around a winding axis 76.
- the winding axis 76 forms a non-zero cutting angle with the flow direction 88 and is in particular 90 °.
- ⁇ 1 At one end of the swirl vane 16 in the region of the trailing edge 70, a different outflow angle ⁇ 1 is generated than at the other end, an outflow angle ⁇ 2 (not equal to ⁇ l), viewed in the direction of a longitudinal axis of the feed 64.
- the outflow angle ⁇ decreases linearly. There may also be a non-linear increase or decrease.
- This distribution in the radial direction 55 of the outflow angle ⁇ likewise suppresses combustion instabilities, so that the operating range for the burner 1 is expanded.
- the flowing medium on the swirl vane 16 with the flow direction 88 in the channel 13 forms the outflow angle ⁇ .
- the swirl vane 16 can be both twisted and have different diameters for the fuel nozzles.
- FIG. 5 shows the arrangement of the different flow vectors of the gas flowing in the channel 13.
- the vector 79 represents the meridional speed component.
- the vector 82 represents the peripheral speed, so that a resulting speed sector 85 results.
- the angle between the resulting speed 85 and the peripheral speed 82 represents the outflow angle ⁇ .
- the angle 90 ° - ⁇ is the complementary angle.
- the outflow angle ⁇ is also the angle between the direction of flow of the flowing medium and a plane which is perpendicular to the longitudinal axis 46 of the burner.
