Definitions
- the invention relates to a burner according to the preamble of claim 1.
- Relatively low pollutant emissions also set, among other things uniform preparation of the fuel-air mixture to be fed to the primary zone and a good degree of burnout; this in particular in combination with burners that work with air support as "low pressure systems” with high fuel atomization and partly wall-side (fuel film on sleeve) and aerodynamic fuel evaporation. Local undesirable fuel accumulations, which could give rise to soot, should be avoided.
- Such a burner for combustion chambers of gas turbine engines is e.g. known from DE-PS 2442895.
- the known burner has, without exception, stationary, that is to say non-controllable, swirl devices for the combustion air to be supplied; there is therefore no possibility of controlling different operating states, such as starting, full load, idling, cruise flight (stationary) with respect to the variable fuel-air throughputs required for this, with the least possible pollution.
- a two-zone combustion chamber concept is known from DE-OS 2460 740, with a high-temperature 1st combustion zone rich in fuel with approximately stoichiometric combustion and one axially downstream, low-fuel and low-temperature, and thus as low in pollutants as possible 2nd or main combustion zone.
- Brake chamber concepts are also complex, technically complex, prone to malfunction and expensive.
- they provide a "variable chamber geometry" in order to supply combustion and possibly mixed air via holes of the hole rows that are controllable in cross-section, by pipe sections of the flame tube jacket of the combustion chamber are displaceable relative to each other in the axial or U direction.
- annular combustion chamber for a gas turbine engine which has a plurality of burners distributed over the circumference at the air inflow-side head end;
- each burner should be assigned an "external" swirl device which can be regulated or blocked with regard to the supply of part of the combustion air;
- the "external” swirl device can be assigned a nozzle-centric, axial fixed swirl device;
- the "external” swirl device with radial inflow is formed between radial wall parts of a nozzle-coaxial central body with obliquely arranged openings arranged uniformly over the circumference.
- the regulation takes place by means of an orifice that can be turned on the outside in the circumferential direction on the central body; This has fingers at openings distributed over the circumference, which partially protrude lengthwise into the openings and, in intermediate positions of the diaphragm, each have an angular position deviating from the openings.
- the invention is based on the object of specifying a burner according to the type mentioned at the outset (preamble of claim 1), in which at least one swirl device enables the air throughput that is operationally required for low-pollutant and homogeneous combustion while maintaining a uniformly pronounced rotary vortex.
- the fingers practically each form a side wall of an opening which is moved with the sleeve in the axial direction and which has a circumferential width £ or. Height and length is designed to match the respective channel height and length.
- the breakthroughs can therefore preferably each form a rectangular or square or rhombic channel cross section, the actual throughflow being formed in each case between the one movable wall and the locally exposed stationary wall sections of the breakthroughs.
- the breakthroughs according to the invention could also be defined or formed as channels or slots.
- the swirl flow and thus the desired rotation vortex geometry which is jointly responsible for optimal preparation of the fuel-air mixture, are not impaired in various intermediate positions. All or a substantial part of the primary air required for low-pollutant combustion can be supplied with the swirl device; with only one adjustable swirl body, the through-flow channels or breakthroughs would have to be dimensioned sufficiently large.
- the invention enables the combination of at least one control or regulatable swirl device with a stationary swirl device which provides a constant air supply over the entire operating state, the fuel supply being varied depending on the load state, the variable one then An air supply is “superimposed” on operating states, which, in adaptation to the respective operating states, enables the air requirement with regard to combustion that is low in pollutants.
- the last-mentioned air requirement can e.g. can be regulated as a function of operationally increasing combustion temperature and / or pressure in the combustion chamber.
- the invention includes the possibility, in certain engine states - as well as depending on the design and range of use of the engine - that is to say when igniting and starting up and, if necessary, under extreme full load. B. to burn stoichiometrically and to burn predominantly, in cruise flight operation, airy and accordingly low in pollutants.
- the swirl means or devices in question can produce rotating or mixed air vortices rotating approximately in the same sense or in opposite directions to the burner or nozzle axis.
- 1 represents a perspective view of a controllable swirl device belonging to the burner in an intermediate position with clarification of radial / tangential air flow through the openings, partly on the outside and inside with respect to a downstream annular body of a central body, with a corresponding sleeve position,
- FIG. 2 shows the perspective view of the swirl device according to FIG. 1, but clarifying a fully open end position of the openings
- FIG. 3 shows the perspective view of the swirl device according to FIGS. 1 and 2, but clarifying a completely closed end position of the openings
- FIGS. 4 is a perspective view of the swirl device according to FIGS. 1 to 3, wherein, omitting the one end wall of the ring body, the profile bodies which are arranged uniformly distributed over the circumference and which form the openings are illustrated in connection with an intermediate position of the sleeve along with fingers,
- FIG. 5 shows a perspective view of the swirl device leaving out the end wall of the ring body according to FIG. 4, but clarifying a position of the sleeve and fingers in which the openings are almost closed
- FIG. 6 shows an axial section of the burner in a first embodiment, at the upstream head end of the combustion chamber together with flame tube and housing parts shown partially broken off, wherein the first burner version consists of the combination of an adjustable and a stationary swirl device in association with a central fuel nozzle
- 7 shows an axial section of a burner in a second embodiment in the combination of two stationary swirl devices with a third controllable swirl device connected downstream thereof, in which, in addition to the head end according to FIG Actuating device of the adjustable swirl device are illustrated,
- Fig. 8 is a view of the burner in viewing direction A of Fig. 7, with further clarification of the actuator and
- FIG. 9 shows an axial section of a burner in a third embodiment, in which the burner along with the central fuel nozzle at the upstream head end of the combustion chamber, two controllable swirl devices and the jointly responsible axially displaceable sleeve and details of the actuating means for this are shown.
- FIGS. 1 to 5 illustrate an adjustable swirl device; in relation to the application, it has an annular body 2 with openings 3 uniformly distributed over the circumference at the downstream end of a central body 1 arranged coaxially to the axis of the burner or the fuel nozzle; an axially displaceable sleeve 4 is seated on the central body 1 and engages in the openings 3 at the downstream end with fingers 5 angled vertically against the axis of the burner.
- the fingers 5 run parallel to the axially spaced straight line
- Walls of the openings 3 have a continuous four-section, in particular a rectangular cross-section; in other words, the fingers 5 represent walls in the openings 3 which can be moved axially with the sleeve 4, in order to achieve the throughput of radially supplied primary air (Arrows P) to regulate (intermediate position according to Fig. 1, 4 or 5) or to shut it off completely (Fig. 3) or to expose it completely (Fig. 2).
- Arrows P radially supplied primary air
- FIG. 5 - intermediate position of the fingers 5 with almost closed breaks 3 - the fingers 5 extend over the respective total length of an opening 5.
- the openings 3 could also be described as "slots"; they could also have a square or, for example, rhombic cross-section, each of the same shape and size, over the entire length in question.
- the respective radial / tangential openings 3 can - according to FIG. 4 - be formed on the central body 1 between wedge-shaped profiled end parts 6 which are evenly spaced in the circumferential direction; the end parts 6 could also be described or designed as blade profiles; this is, for example, similar to the way they are known from wedge-shaped diffuser blade profiles, without, however, being intended to form a diffuser here. Otherwise, the end parts could also be described as "wedge-shaped tooth-like". For example, from FIGS.
- the sleeve 4 always encompasses a wedge-shaped end part 3 or profile with two fingers 5 spaced or adjacent in the circumferential direction; in places, in each case between the fingers 5, the sleeve 4 also sits axially displaceably on the outer peripheral surfaces of the end parts 3 or profiles; these outer peripheral surfaces are therefore part of the outer cylindrical peripheral contour of the central body 1 interrupted by the openings 3; this outer "seating" of the sleeve 4 is important in order to ensure that the openings 3 are shut off as perfectly as possible (FIG. 3).
- the fingers 5 or “side walls” of the openings 3 or channels as control bodies which can be displaced axially together with the sleeve 4, on the inside of the sleeve, for example by welding; this can be advantageous when it comes to controlling several adjustable swirl devices simultaneously with one sleeve; and similar or comparable to one l arrangement according to FIG. 9 described later.
- the relevant fingers 5 or “control body” in relation to the arrangement of a burner of a combustion chamber — are angled or bent radially from the downstream outer end face of the sleeve 4.
- the design according to FIGS. 1 to 5 enables - in spite of a variable air flow change from the closed end position (FIG. 3) via intermediate positions, e.g. Fig. 1, up to the complete release (Fig.2) of the breakthroughs 3- an unchanged swirl generation, and thus rotation vortex formation.
- the specified swirl device can, in the outlet-side wall shield, coaxially to a central fuel nozzle, possibly. can be used for the sole quantity-adjustable control for the total or predominant supply of primary air. Together with the adjustable swirl device, the remaining primary air could optionally be supplied locally via special openings in the flame tube, specifically via the outer secondary air duct, between the outer housing of the combustion chamber and the flame tube.
- FIG. 6 illustrates an advantageous burner variant in the combination of a swirl device 7, which can be regulated with regard to the throughput of a part of the radially supplied primary air, in the sense of FIGS. 1 to 5, with a stationary swirl device 8 which is arranged directly axially downstream 9 and connected to a pipe 10 for fuel bent radially upwards.
- the stationary swirl device 8 likewise has radial / tangential openings 11, but for the throughput of a primary air component which remains constant over the entire operating state.
- a radial shielding wall 12 separates the openings 3, 11 axially from one another and, radially / axially bent, sits as a coaxial to the nozzle axis or to the axis 13 of the burner downstream sleeve (Venturi tube) in the direction of the Primary zone 14 continues.
- the swirl devices 7, 8 With an end part 15 which diverges in the direction of the flow, the swirl devices 7, 8 are fixed at the downstream end to the wall parts 16, 17 forming the rear wall of the flame tube 18.
- the openings 3, 11 can be made radially / tangentially in the same direction or in opposite directions in order to impress the respective emerging air currents (arrows L, G) in the same direction of rotation or rotating vortices W, W1 rotating in opposite directions.
- the central body 19 of the burner, on which the sleeve 4 is axially displaceable, is made in several parts in the present case; it consists of ring-like or sleeve-like components 20, 21 flanged together, between which a radial shielding wall 22 with a fuel nozzle 9 is held.
- the already mentioned rounded end part 15 is expanded aerodynamically to the full primary zone cross section with the sections 16, 17 of the rear wall, thermally shielding baffles 22, 23 radially outwards; In this way, an almost non-detachable air distribution via the end part 15 is also achieved on the radially outer part of the primary zone.
- 24 and 25 denote thermally insulating shielding walls or wall parts, inside, on the flame tube 18.
- FIG. 6 On the central body 19, a ring component 26 overlaps the sleeve 4, the sleeve 4 engaging with a pin 27 in a slot 28 of the ring component 26 which runs obliquely to the axis 13 of the burner; a circumferential rotation of the ring member 26 on the central body 19 causes an axial adjustment of the sleeve 4; an arm 29, which projects radially from the ring component 26, pivotably engages via hinge point 29 'on an adjusting ring 30 which is adjustable in the circumferential direction on the outer housing 45 (FIG.
- a portion of the compressor air supplied in the direction of arrow V via a diffuser 31 (FIG. 7) is radially supplied to the swirl devices 7, 8 (FIG. 6) as primary air P via chambers 32, 33 on the head side.
- the arrows B symbolize the fuel injected from the fuel nozzle 9 (spray cone).
- Portions of the supplied fuel B can flow downstream along the inner wall of the sleeve-like part of the shielding wall 12 (vortex film) and, if necessary, evaporate there and be integrated on the air side (L, G); the swirl devices here, for example downstream of the burner in the primary zone 14, produce rotational vortices W, W1; due to the relatively large shear forces that are generated when the two opposing rotational vortices W, W1 flow together, fuel arriving and draining off can be distinctly nebulized at the leading edge or tear-off edge 34 of the sleeve part of the wall 12.
- FIG. 7 embodies a burner design in which the adjustable swirl device 7 is arranged after a first and second swirl device 35 and 36 containing stationary radial / tangential openings.
- the controllable swirl device 7 a substantial proportion of the total primary air to be supplied can be fed to the primary zone 14 in a load-dependent manner in the interest of low-pollutant combustion.
- the arrows G and H, K symbolize the respective throughflow and outflow directions of the relevant primary air fractions - seen from right to left;
- G, H, K primary air fractions supplied under swirl - from outside to inside - decreasing in diameter, e.g. each other produces opposite rotating vortices, into which fuel B supplied via the fuel nozzle 9 is atomized or mist-like and homogeneously integrated.
- the first stationary swirl device 35 is assigned to the fuel nozzle 9 in the direction of the flow.
- An axially radially bent shielding wall 37 between the swirl device Tung 7.36 acts as a carrier of the axially displaceable sleeve 4.
- the Zentra arranged coaxially to the axis 13 of the burner.
- the body of the burner includes - seen from left to right - a sleeve-like component 38, the radial shielding wall 22 on the nozzle side, the swirl devices 35, 36, 7, the shielding wall 37 and the end part 15 which is rounded at the end; this is arranged downstream of the controllable swirl device 7 and at the same time is a means for holding the central body on the wall parts 16, 17 of the flame tube rear wall.
- An axial diffuser for the air V removed on the compressor end side and fed to the combustion chamber is denoted by 31.
- a portion of the air V supplied as primary air P flows into the head end of the combustion chamber via openings 39 in a closure hood 40 of the burner, in order to be fed from there via the chambers 32, 33 to the swirl devices 35, 36, 7.
- the already mentioned radial shielding wall 37 between the swirl devices 36, 7 continues as a stro openly open sleeve 41, which is bent radially outward in the sense of the rounding of the end part 15; a sleeve 42 closest to the fuel nozzle 9 is part of a shielding wall between the swirl devices 35, 36.
- a remaining part of the compressor air V supplied via the axial diffuser 31 flows as secondary air (arrows S) into annular spaces 43, 44, between outer housing walls 45, 46 and flame tube 18 of the combustion chamber in order to, among other things, from there to the flame tube 18 as mixed air (dilution air) and as tertiary air (equalization of the temperature profile and reduction of the temperature at the combustion chamber outlet).
- the ring component 26 is rotatably guided in the circumferential direction with the oblique guide slot 28 (FIG. 8) into which the pin 27 connected to the axially displaceable sleeve 4 projects.
- Positions 29, 29 'and 30 - lever arm articulation point, adjusting ring - of the adjusting system are practically identical to that according to FIG. 6; 7 shows that the adjusting ring 30 is rotatably supported and supported on the outer housing 45 by means of rollers 47 in the circumferential direction.
- FIG. 9 is a variant of the burner, modified in particular in relation to FIG. 6, according to which two adjustable swirl devices 7, 47, which follow one another in the axial direction, are provided on the central body 19; ring bodies of the two swirl devices 7, 47, fingers 5, 48 of an axially displaceable sleeve 4 'engage in the openings 3, 11; the sleeve 4 'is seated on a radial shielding wall 12', with a section widening in a step-like manner, between the axially spaced openings 3, 11, so as to be axially displaceable.
- the sleeve 4 '- as described in relation to FIG. 6 - is axially displaceable on the central body 19 (part 21).
- the sleeve 4 ' is provided with openings 49 which ensure the relevant supply of the primary air portion to the openings 3.
- the entire primary air P or a substantial part of it can be supplied to the primary zone 14 via the two swirl devices 7, 47 depending on the load and for the purpose of combustion that is as low in pollutants as possible.
- a pronounced swirl and rotation vortex formation (see also W, W 1- Fig. 6) is not impaired despite the variably controllable or regulatable primary air supply.
