Definitions
- the present invention relates to a burner according to the preamble of claim 1.
- Step on the outer boundary of the swirl flow field particularly low speeds because at constant Total pressure in the arrangement of the static pressure from the inside rises to the outside, causing the dynamic pressure caused by the absolute speed is represented with increasing Radius is getting smaller. These low speeds may no longer be able to prevent the flame from the combustion chamber, along the boundary layer, into the burner. reproduces and can then overheat and destroy it.
- the document DE-A1-44 09 918 describes a burner for operating a combustion chamber.
- This burner consists essentially of at least two hollow, conical ones Partial bodies whose axes of longitudinal symmetry are offset from one another, which means that they flow opposite air inlet slots for a combustion air flow arise.
- the burner points to the regularly arranged openings on the entire surface through which a gaseous Fuel with a certain calorific value is injected into the cone cavity. The Injection of the gas is injected at high speed, so that in front of the flame front a homogeneous mixture is present.
- the invention seeks to remedy this.
- the invention how it is characterized in the claims, the task lies based on precautions for a burner of the type mentioned to meet those capable of a flashback to prevent safely.
- the main advantage of the invention is that that this additional device of the simplest design is, and be installed as required in the burner mentioned can intervene without changing the basic concept of the same to have, with which such a burner, which is at medium compressor pressure ratios already well proven has, also for the further development stages of Gas turbines can be taken over and used.
- additional air is injected along made of the burner walls, preferably in the downstream half of the burner.
- This additional air forms a film along the wall and mixes it then slowly with the fuel-enriched main flow.
- the essential improvement in security against one Backfire is based on two principles.
- a weighty dilution of the mixture is carried out. There the burner is operating near its lean extinguishing limit weak local dilution of the mixture results along the walls to the desired loss of flammability of the mixture along the walls.
- this additional air is injected so that the axial speed is increased along the wall, which is also convenient affects the operation of such a burner.
- the pulse density ratio between film air and main flow in the range of 1 since both flows are common be accelerated from the same total pressure. Other impulses are also easily conceivable, they have striven for Effect no negative effects.
- Fig. 1 shows a burner in a perspective view.
- Fig. 2 For a better understanding of the subject, it is advantageous if at the same time when studying Fig. 1 based on the description Fig. 2 is also used.
- Partial bodies 1, 2 which are nested offset from one another are.
- Conical here not just the one shown, with a fixed opening angle understood cone shape understood, but it closes also other configurations of the partial bodies, one such Diffuser or diffuser-like shape as well as a confuser or confuser-like shape. These forms are present not shown, since it is the person skilled in the art are common.
- the displacement of the respective central axis or Longitudinal axis of symmetry of the partial bodies 1, 2 to one another see Fig. 2, Pos.
- the two tapered Partial bodies 1, 2 each have a cylindrical initial part 9, 10, which also, analogously to the aforementioned partial bodies 1, 2, offset to each other, so that the tangential Air inlet channels 5, 6 over the entire length of the Brenner are present.
- a nozzle 11 for preferably atomizing a liquid fuel 12 housed such that their injection approximately with the narrowest cross section of the the partial body 1, 2 formed conical cavity 8 coincides.
- the injection capacity and the operating mode of this Nozzle 11 depends on the given parameters of the respective Burner.
- the fuel injected through the nozzle 11 12 can be enriched with a recirculated exhaust gas if necessary become; then it is also possible through the nozzle 11 to provide the complementary injection of a quantity of water.
- the burner can be purely tapered, i.e. without cylindrical initial parts 9, 10 may be formed.
- the partial body 1, 2 each have a fuel line 13, 14, which along the tangential inlet channels 5, 6 arranged and provided with injection openings 15, through which preferably a gaseous fuel 16 in the combustion air 7 flowing there is injected, as this is symbolized by arrows 16, these Injection at the same time the fuel injection level (see Fig. 3, item 22) of the system.
- These fuel lines 13, 14 are preferably at the latest at the end of the tangential inflow, before entering the cone cavity 8, placed this to ensure an optimal air / fuel mixture.
- the burner On the combustion chamber side, the burner has an anchor for the partial body 1, 2 serving front panel 18 with a number Bores 19 through which a mixing or Cooling air 20 or the front part of the combustion chamber 17 Wall is fed.
- Liquid fuel 12 is used to operate the burner the central nozzle 11 is used, this is under one acute angle in the cone cavity 8 or in the combustion chamber 17 injected. A nozzle is thus formed from the nozzle 11 Fuel profile 23, which flows in from the tangential rotating combustion air 7 is enclosed. In axial Direction is the concentration of the fuel injected 12 continuously through the incoming combustion air 7 an optimal mixture degraded. If the burner with a operated gaseous fuel 16, this can in principle also happen via the fuel nozzle 11, preferably but this is done via the injection openings 15, wherein the formation of this fuel / air mixture right at the end the air inlet channels 5, 6 comes about.
- a backflow zone also forms there or backflow bladder 24 (vortex breakdown) with one opposite the flame front 25 acting there stabilizing Effect one, in the sense that the backflow zone 24 has the function of a disembodied flame holder.
- the optimal fuel concentration across the cross-section is only in the area of vertebral bursting, i.e. in the area the backflow zone 24 reached. Only at this point then a stable flame front 25.
- the flame stabilizing Effect results from the cone cavity 8 forming swirl number in the direction of flow along the cone axis. The flame strikes back inside the burner therefore occurs due to this fluidic specification not on.
- Fig. 2 shows the same burner according to Fig. 1 but from a different one Perspective and in a simplified form.
- This figure 2 mainly wants the disposition of the two conical ones Show part body 1, 2 and their offset to each other.
- the Displacement of the respective central axis 3, 4 of the two partial bodies to each other, based on the main central axis 26 of the Burner, which is the main axis of the central fuel nozzle 11 corresponds to the respective size of the flow openings the tangential air inlet ducts 5, 6.
- the central axes 3, 4 run parallel to each other here.
- Zone 27 in which the placements of Means for the injection of additional air takes place.
- FIGS. 4 and 5 show a development 28 of a conical partial body, which schematically shows zone 27 within which has a specific configuration of injection openings for additional air, which ensure a reignition lock, is taken as a basis.
- the orientation of the injection openings 29 as well as their number and size will be the respective Flow conditions in the burner adjusted.
- the final Purpose is primarily aimed at the reignition barrier.
- the individual oblique lines 30 want the placement of the symbolize individual rows of the injection openings 29.
- the arrows 31 point to the outflow direction of the Additional air indicate that is at right angles to the Level 30 of the injection openings 29 runs. This outflow direction can, however, range from purely axial to direction the main flow vary. For better understanding are in this processing 28 a single row and one Double row of injection openings 29 shown. The corresponding cuts are then shown in FIGS. 4 and 5.
- Fig. 4 shows the design of a simple row of injection openings 29.
- the additional air 32 is here under one injected acute angle with respect to the swirl flow 7a, that is flat to the inner wall of the corresponding partial body 2, this around improve film production.
- FIG. 5 shows a double row of injection openings 29. Basically, the same precautions are taken here as described in Fig. 3.
- the injection openings 33 run in the area the inner wall of the corresponding partial body 2 fan-shaped, as shown in Fig. 7, which is a plan view.
