Definitions

  • the invention relates to a burner for an internal combustion engine and an internal combustion engine.
  • the internal combustion engine is in particular a gas turbine in the megawatt power range, preferably for a power plant with a power of several hundred megawatts.
  • the internal combustion engine typically comprises a plurality of burners, for example, in a ring arrangement and a compressor upstream of the burners and a turbine connected downstream of the burners.
  • each of the burners comprises a combustion region which is arranged in the interior of a combustion chamber of the internal combustion engine.
  • Each of the combustion regions is part of a combustion chamber which substantially corresponds to the interior of the combustion chamber.
  • This combustion chamber is, for example, annular, that is, as an annular combustion chamber, along which the burners are arranged.
  • a suitable fuel / air mixture is first injected and then burned.
  • the fuel is, for example, natural gas.
  • nozzles are typically provided, which run parallel to each other and in which the fuel / air mixture is respectively formed before it is injected into the combustion chamber, that is, in particular the combustion region.
  • the nozzles are often arranged annularly, sometimes along several concentric rings.
  • the nozzles each have a nozzle outlet which opens into the combustion chamber.
  • the nozzles near the nozzle outlets are connected to a nozzle carrier, which at the same time constitutes the upstream end of the combustion chamber, and in particular the combustion chamber from one on the other side of the combustion chamber Düsentheses lying nozzle chamber separates.
  • the nozzle carrier thus also serves as a cover plate.
  • the burner is designed for use in an internal combustion engine, in particular a gas turbine in the megawatt power range, and comprises a pilot burner which extends in the axial direction, a nozzle chamber and a combustion region. Furthermore, the burner comprises a cover plate, which is arranged between the nozzle chamber and the focal region and which has an inlet opening. In addition, an adapter is arranged for guiding air from the nozzle chamber along a predetermined flow path in the direction of the combustion region.
  • an embodiment of the burner is made possible in lightweight construction, as is dispensed through the adapter to a massive nozzle carrier, whereby the burner is also inexpensive to manufacture.
  • the burner is particularly easy to assemble, in particular it is advantageously possible to assemble the components of the burner through the combustion chamber of the internal combustion engine.
  • Another advantage is in particular that by means of the adapter at least a portion of the air is particularly efficient fed to the pilot burner as combustion air.
  • the cover plate advantageously prevents smoke and / or exhaust gases from reaching the combustion chamber into the nozzle chamber. This is achieved in particular by the air flowing along the flow path into the combustion region. In other words, although a fluidic connection exists between the nozzle chamber and the combustion region, the penetration of exhaust gases into the nozzle chamber is prevented, in particular, by the fact that air flows from the nozzle chamber into the combustion region.
  • the internal combustion engine has a general flow direction, which points from the compressor in the direction of the burner towards the turbine.
  • the terms used in the following upstream and downstream are to be understood in particular with respect to this general flow direction.
  • the pilot burner extends along a longitudinal axis and is in particular arranged centrally in the burner.
  • the pilot burner is used to supply a fuel, in particular oil in the combustion area.
  • a number of nozzles are arranged, each extending parallel to the longitudinal axis, that is to say also in the axial direction.
  • the nozzles are arranged in the nozzle chamber and each have downstream of a nozzle outlet, which corresponds to a respectively introduced into the cover plate recess.
  • Words the nozzles each lead into the focal area.
  • the nozzles are arranged in particular on a number of rings, the center of each of which lies on the longitudinal axis.
  • Each ring of nozzles is also called a stage. In the case of several stages, the rings are preferably arranged concentrically.
  • Upstream of the nozzles are formed in particular for receiving air from the nozzle chamber, that is, have a suitable nozzle inlet into which in particular in each case a burner lance for supplying fuel protrudes.
  • the air provided in the nozzle chamber is, in particular, compressed air, which is conducted into the nozzle chamber from a compressor of the internal combustion engine arranged upstream of the burner.
  • the nozzle chamber thus serves in particular as a reservoir for compressed air.
  • the nozzle chamber is fluidically connected to the combustion region, whereby a supply of the pilot burner with air as combustion air is made possible.
  • the adapter serves in particular for suitable guidance of the air, that is to say in particular of an air flow along a suitable flow path.
  • the air in this case has a flow direction, which is generally oriented from the nozzle chamber in the direction of the focal region.
  • the flow direction does not generally correspond to the axial direction, but may change along the flow path.
  • the adapter allows a deflection of the air in a particularly suitable manner.
  • a flow channel is formed between the adapter and the cover plate, whereby a suitable flow path is realized in a particularly simple manner.
  • the flow channel is therefore limited by the adapter and the cover plate, that is, the adapter and the cover plate each form a boundary of the flow channel.
  • the flow channel is in particular a flow space which extends around the inlet opening in such a way that the air is at a predetermined position in the flow space each flows substantially in the direction of the inlet opening.
  • the adapter in a further preferred embodiment, a head portion into which projects the pilot burner.
  • the head area encloses the downstream end of the pilot burner and in particular also the outlet opening.
  • annular channel is expediently formed between the pilot burner and the head region.
  • the air is thereby introduced particularly uniformly.
  • the pilot burner or at least its end in particular has a circular border; Likewise, the inlet opening is circular.
  • part of the cover plate is designed as an axial cone, at the upstream end of which the inlet opening is arranged.
  • the axial cone is arranged in the center of the cover plate and widens in the opposite direction to the pilot burner, that is, downstream.
  • the axial cone thus forms in particular a cone-shaped extension of the combustion chamber in the direction of the burner.
  • the axial cone is in this case also referred to as axial lattice cone and serves accordingly for improved guidance or introduction of the fuel / air mixture in the direction of the combustion chamber.
  • the adapter has a diagonally extending portion which extends at a distance from the axial cone and thereby forms a cone-shaped portion of the flow channel.
  • the cone-shaped portion is also referred to as a diagonal section.
  • an axial swirler is arranged between the inlet opening of the axial cone and the outlet opening of the pilot burner, for improved mixing of air supplied by means of the annular channel and fuel supplied by means of the pilot burner.
  • the axial swirler extends at least partially past the end of the pilot burner and into the annular channel.
  • the Axialverwirbler is expediently surrounded or surrounded by a collar which is formed in particular on the axial cone. In this case, the Axialverwirbler is disposed within the collar and the outer side of the collar forms in combination with the adapter an advantageous extension of the diagonal portion of the flow channel.
  • the adapter For cooling the cover plate by means of the air, the adapter has a radially extending, annular portion, which forms a radial portion of the flow channel with the cover plate.
  • the radial section of the flow channel is also referred to as a radial section.
  • the annular portion of the adapter and the cover plate include an annular flow space through which the air flows substantially in the radial direction and in the direction of the diagonal portion.
  • each of the nozzles extending in the axial direction in the flow channel forms an interruption.
  • the nozzles each have an end portion which is arranged in the flow space, that is to say in the radial section and is thereby advantageously surrounded by the air flowing there.
  • the adapter is shaped in particular in the manner of a bell, wherein the head portion forms an upper bell portion and the diagonal portion forms a lower part of the bell, which in turn is followed by the radial portion.
  • the three sections are formed either in one piece or the radial section and the bell are separate, interconnected parts.
  • the air flowing out of the nozzle chamber is then drawn in via the outer edge of the radial section and flows along the nozzle-chamber-side wall of the cover plate into the lower part of the bell.
  • the cover plate is cooled by means of the air.
  • the air flows along the axial cone and in particular also cools it.
  • the flow direction on the diagonal section is substantially opposite to the general flow direction in the internal combustion engine.
  • the air flows into the head region and is deflected there in such a way that the direction of flow of the air essentially corresponds to the general direction of flow.
  • the air is guided along the downstream end of the pilot burner and finally provided in the combustion area as combustion air for the pilot burner.
  • the air thus flows generally from outside to inside along the inner wall of the adapter.
  • the flow channel is designed as an annular space.
  • annular space is understood in particular to mean that the flow channel is a space enclosed by suitable side walls, which has an extension in at least one direction transverse to the flow direction which is comparable to the length of the flow channel in the flow direction of the air.
  • the flow channel formed as an annular space can be made particularly cost-saving and is also lighter in terms of its weight.
  • the cover plate advantageously increases.
  • the latter preferably has an air inlet lying in the radial direction.
  • an air flow is formed from outside to inside and a particularly large part of the cover plate is cooled by means of the air flowing past it.
  • the air inlet is in particular annular and is then also referred to as a ring inlet. This has a radius which is in particular greater than the radial distances of the nozzles to the longitudinal axis of the burner. The air is thus sucked in from the outside of the nozzle area with respect to the nozzles. Due to the outer layer of the air inlet also a particularly large flow cross-section can be achieved. Thus, a corresponding amount of air is available for cooling and then for introduction into the combustion area.
  • annular gap is formed in the radial direction between the pilot burner and the adapter, into which a sealing ring is inserted. This serves, in particular, to prevent or at least reduce an inflow of air out of the nozzle chamber through the gap, that is to say past the pilot burner into the head interior enclosed by the head region of the adapter.
  • the sealing ring is attached to one of the two parts, namely the pilot burner or the adapter and displaceable relative to the other of these two parts.
  • the sealing ring is thus either attached to the pilot burner and displaceable relative to the adapter or attached to the adapter and displaceable relative to the pilot burner. Due to the thermal load of the various parts of the burner, which is usually present in operation, a thermal expansion results, which may also be different for different parts or directed in different directions.
  • the displaceability of the Sealing piston then allows in particular an avoidance of tension of the pilot burner against the adapter and possibly resulting damage.
  • the sealing ring has at least one web which extends in the axial direction and rotates the sealing ring, wherein the web forms a sealing surface which abuts on the adapter.
  • the sealing ring thus has an approximately H-shaped cross-section and is therefore particularly economical to produce, at the same time suitable sealing effect.
  • the adapter has at least one spacer, which abuts on the cover plate.
  • the spacer is attached to the diagonal portion of the adapter and abuts the axial cone, whereby in particular at the same time a suitable spacing in the radial and in the axial direction takes place.
  • the mounting of the burner is simplified by the spacer so that when assembling automatically a suitable spacing and alignment, in particular centering of the cover plate, the adapter and the pilot burner takes place.
  • the spacer is formed as a deformation of the adapter.
  • a suitable spacer can be produced in a particularly simple manner.
  • the spacer is designed as a dimple, nub or cam and constitutes an elevation or depression along the surface of the adapter.
  • a plurality of spacers are provided, in particular for improving the spacing during assembly and for improved centering with respect to the longitudinal axis of the burner. In the case of several spacers, these are in particular distributed uniformly in the direction of rotation of the adapter.
  • the adapter and the cover plate are each made of sheets, that is, with a low material thickness, whereby the burner can be produced in an advantageous lightweight construction.
  • the material thickness is in particular about 1-4 mm in the case of both the adapter and the cover plate.
