Abstract

The invention relates to a compact burner for the pressurized gasification of pulverized fuel dust for producing synthesis gas, wherein a plurality of concentric media channels transition into a conical burner tip. Said burner tip provides a reduced contact surface on the reaction chamber side. The nozzle components of the burner tip are produced by means of selective laser melting, which permits a design for cooling by means of supplied media, such as fuel gas, flushing gas, or oxidation means. A sliding guide having an intermediate seal is arranged between the nozzle components of two media channels to equalize temperature-driven linear extensions. The compact burner according to the invention makes the expense for liquid cooling unnecessary.

Kompaktbrenner für einen Flugstromvergaser, bar einer Compact burner for an air flow gasifier, bar one
Flüssigkeitskühlung liquid cooling
Die Erfindung betrifft einen Kompaktbrenner für die Druckvergasung von Brennstäuben zur Erzeugung von Synthesegas. The invention relates to a compact burner for the pressure gasification of fuel dusts for the production of synthesis gas.
In Reaktoren zur Flugstromvergasung von Brennstäuben unter erhöhtem Druck zu Synthesegas kommen Pilot- und Hauptbrenner für die Zuführung sämtlicher Medien zum Einsatz, die reakti- onsraumseitig mehrfach wassergekühlt sind. Die Wasserkühlun¬ gen sind durch Druckräume gegeben, die zum Reaktionsraum hin eine vergrößerte Angriffsfläche für die Brennerflamme und die heißen Gase aus dem Reaktor darstellen. Überwiegend durch An- und Abfahrvorgänge verursacht hat die reaktionsraumseitige Brennerspitze eine begrenzte Lebensdauer. Dabei erfordern be¬ sonders die mit Kühlwasser betriebenen und als geschlossene Druckräume ausgebildeten Brennerkühlteile einen hohen In reactors for the flow-stream gasification of combustion dusts under increased pressure to syngas, pilot and main burners are used for the supply of all media, which are water-cooled several times on the reaction side. The Wasserkühlun ¬ gen given by pressure chambers, which represent an enlarged contact surface for the burner flame and the hot gases from the reactor to the reaction compartment. Predominantly caused by startup and shutdown, the reaction chamber side burner tip has a limited life. Here be ¬ Sonders the operated with cooling water and designed as a closed pressure chambers burner cooling parts require a high
Instandhaltungsaufwand bei den wiederkehrenden Brennerrepara¬ turen. Die verschiedenen zuzuführenden Medien, wie zum Beispiel Brenngas, Brennstaub und Oxidationsmittel , haben unter¬ schiedliche Temperaturen und erfordern baulich aufwendige Maßnahmen (z. B. Wellrohrkompensatoren) zur Aufnahme der un- terschiedlichen Dehnungen der Brennerkanalwände. Maintenance costs for the recurring Brennerrepara ¬ tures. The various media to be supplied, such as fuel gas, pulverized fuel and oxidant have schiedliche under ¬ temperatures and require structurally complicated measures (z. B. Wellrohrkompensatoren) for receiving the un- terschiedlichen expansions of the burner channel walls.
Aus der DE 102007040890 ist ein Kohlenstaubkombinationsbrenner mit integriertem Pilotbrenner bekannt. Aus der CN2688677Y ist eine Vergasungsdüse bekannt, bei der an der Verbindungsstelle zwischen Innenspritzrohr und Außen- spritzrohr eine Gleitdichtung zum Ausgleich von Längenänderungen angeordnet ist. Der Erfindung liegt das Problem zugrunde, einen Brenner für die Druckvergasung von Brennstäuben zur Erzeugung von Synthesegas zu schaffen, dessen Brennerspitze ohne Zuführung einer Kühlflüssigkeit Standzeiten erreicht, wie herkömmliche From DE 102007040890 a coal dust combination burner with integrated pilot burner is known. CN2688677Y discloses a gasification nozzle in which a sliding seal is arranged at the connection point between the inner injection pipe and the outer injection pipe to compensate for changes in length. The invention is based on the problem of providing a burner for the pressure gasification of fuel dusts for the production of synthesis gas whose burner tip without supplying a Coolant life reaches as conventional
Flüssigkeits-gekühlte Brennerspitzen . Liquid-cooled burner tips.
Das Problem wird durch einen Brenner mit den Merkmalen des Anspruchs 1 gelöst. The problem is solved by a burner having the features of claim 1.
Die Kühlung der Brennerdüsen durch aufwändige, wassergekühlte, geschlossene Druckteile wird ersetzt durch Betriebsmedien gekühlte Düsen, die konstruktiv entsprechend ausgestaltet sind. The cooling of the burner nozzles by complex, water-cooled, closed pressure parts is replaced by operating media cooled nozzles, which are structurally designed accordingly.
Der für die bisherigen Wasserkühlungen der Brennerspitze erforderliche Aufwand kann anlagenseitig eingespart werden. Die Brennerdüsenteile werden durch generative Verfahren schichtweise aufgebaut und dabei weitgehend endgefertigt. The effort required for the previous water cooling the burner tip can be saved on the system side. The burner nozzle parts are built up in layers by generative processes and are largely finished.
Das für den schichtweisen Aufbau eingesetzte Verfahren verwendet ein metallisches Pulver, das partiell mittels Laser- strahl verschmolzen wird, das überschüssige Pulver abschlie¬ ßend entfernt wird und die gewünschte Bauteilkontur abschlie¬ ßend entnommen werden kann. The method used for the layered structure using a metallic powder which is partially melted by means of laser ray, which is lockable excess powder ¬ ßend removed and can be removed, the desired component contour lockable ¬ ßend.
Bei dem generativen Herstellungsverfahren handelt es sich um das SLM-Verfahren (Selektive Laser Melting) . The generative manufacturing process is the SLM (Selective Laser Melting) process.
Gegenüber dem bisherigen spanenden Herstellungsverfahren aus Schmiedeteilen wird der Fertigungsaufwand für die Brennerdü¬ sen um mehr als 80 % gesenkt. Compared to the previous cutting production method of the forged parts of the manufacturing expense for the Brennerdü ¬ sen is reduced by more than 80%.
Durch den Einsatz des Laser Melting Prozesses als Fertigungsverfahren für die Düsenteile können durch konventionelle Me¬ thoden nicht oder nur sehr schwer herstellbare Konturen in zufriedenstellender Qualität erzeugt werden, wie beispiels- weise enge Medienkanäle oder der ca. 0,7 mm große, der ge¬ knickten Düsenkontur folgende Kanal für einen Temperatursensor . Mittels Einbringung von Temperatursensoren an den Brennerdüsenteilen in einer im Normalbetrieb relativ geschützten Position können Rückschlüsse auf die Prozessbedingungen an der Brennerspitze und den Verschleißzustand gewonnen werden. By using the laser melting process as a manufacturing method for the nozzle parts ¬ methods can not by conventional Me or very difficult to prepare contours are generated in satisfactory quality as beispiels- as close media channels or approximately 0.7 mm, the ge ¬ nozzle contour buckled the following channel for a temperature sensor. By introducing temperature sensors to the burner nozzle parts in a relatively protected in normal operation position conclusions on the process conditions at the burner tip and the state of wear can be obtained.
Durch die Ausführung dünnwandiger Düsenteile wird neben deren guter Kühlung durch die Betriebsmedien eine Optimierung der Vermischung der reagierenden Medien und damit des Umsatzes von Brennstoff und Oxydationsmittel erreicht. By carrying out thin-walled nozzle parts, in addition to their good cooling by the operating media, an optimization of the mixing of the reacting media and thus of the conversion of fuel and oxidant is achieved.
Zur Einstellung auf wechselnde Brennstoffe ist die Anpassung des Dralls des Oxydationsmittels von Vorteil, was hier durch Einbringung einer Trennwand in den Oxydationsmittelkanal er¬ reicht wird. Dabei kann in einem Kanal das Medium axial unverdrallt und im anderen durch Leitbleche- oder schaufeln verdrallt der Brennerspitze zugeführt werden. Durch die Men¬ genregelung der beiden Teilströme kann an der Brennerdüse der gewünschte resultierende Drall eingestellt werden. Der Einsatz von Gleitführungen mit Abdichtung an den Düsen zwischen den Medien befreit die Bauteile von Spannungen aus behinderter Wärmedehnung und beseitigt den Aufwand für Zu- satzmaßnahmen wie Dehnungskompensatoren in den Medienkanal- wänden . To adjust to changing fuels, the adaptation of the twist of the oxidizing agent is advantageous, which is achieved by introducing a dividing wall into the oxidant channel . In this case, the medium can be axially untwisted in one channel and the burner tip are supplied in the other by baffles or vanes. By the Men ¬ gene control of the two partial flows of the desired resulting swirl can be adjusted at the burner nozzle. The use of sliding guides with a seal at the nozzles between the media frees the components from tensions caused by impaired thermal expansion and eliminates the expense of additional measures such as expansion compensators in the media channel walls.
Durch übliches Anschweißen ohne weitere Druckprüfungen wird im Instandhaltungsfall der Düsenwechsel weitgehend verein¬ facht . Die Einhaltung der technischen Regularien des Druckbehälterbaues kann entfallen und somit entsteht eine Kostensenkung für Neubau und Reparaturfall des Brenners. By usual welding without further pressure tests the nozzle change is largely verein ¬ facht in the maintenance case. Compliance with the technical regulations of the pressure vessel construction can be omitted and thus creates a cost reduction for new construction and repair of the burner.
Vorteilhafte Weiterbildungen der Erfindung sind in den Unter- ansprüchen angegeben. Die Erfindung wird im Folgenden als Ausführungsbeispiel in einem zum Verständnis erforderlichen Umfang anhand von Figuren näher erläutert. Dabei zeigen: Fig 1 den prinzipiellen Aufbau einer erfindungsgemäßen mediengekühlten Brennerspitze, Advantageous developments of the invention are specified in the dependent claims.

In Fig 1 ist der prinzipielle Aufbau einer mediengekühlten Brennerspitze gezeigt, deren Angriffsfläche (1) reaktions- raumseitig reduziert ist. Die Düsenteile (2, 3, 4, 5) sind so gestaltet, dass sie mittels einer definierten Spülgasmenge, wie zum Beispiel Stickstoff, oder durch ein Betriebsmedium, wie zum Beispiel Brenngas oder Oxidationsmittel , ausreichend gekühlt werden. Sie sind keine Teile eines Druckbehälters mehr und in ihrer Form an die kostengünstige Fertigung mittels generativer Verfahren wie dem SLM-Verfahren (Selektive Laser Melting) angepasst. Die bisherige material- und zeit¬ aufwendige, zerspanende Herstellung aus Schmiedeteilen wird weitgehend reduziert. Die medienbedingte unterschiedliche Wärmedehnung der die einzelnen Brennerkanäle abtrennenden Rohre (6) ist unbehindert an den Gleitführungen (7) der Brennerdüsen spannungsfrei möglich und benötigt keine Dehnungs¬ ausgleicher zur Kompensation mehr. Über Dichtungen (8) wird eine zu frühe Vermischung der Medien an den Gleitführungen1 shows the basic structure of a media-cooled burner tip whose attack surface (1) is reduced reaction chamber side. The nozzle parts (2, 3, 4, 5) are designed so that they are sufficiently cooled by means of a defined amount of purge gas, such as nitrogen, or by an operating medium, such as fuel gas or oxidant. They are no longer parts of a pressure vessel and adapted in their shape to the cost-effective production by means of generative processes such as the SLM process (Selective Laser Melting). The previous material and time ¬ consuming, machining production of forgings is largely reduced. The media-related differential thermal expansion of the individual burner ducts separating pipes (6) is unimpeded on the sliding guides (7) of the burner nozzles tension-free possible and no strain compensation ¬ compensation for compensation more.

(7) prevented in the burner. Structurally, the compact nozzles (2) and (4) ensure that the reaction-side, which is particularly important for the supply of the oxidizing agent Outlet contours are independent of changes due to thermal expansion of the tubes (6) of the media channels.
Durch den Einsatz des SLM-Herstellungsverfahrens der Düsen ist die Erzeugung sehr enger, insbesondere auch geknickterBy using the SLM manufacturing process of the nozzles, the generation is very narrow, in particular also kinked

Die An¬ ordnung eines integrierten Drallkörpers (9) bringt zum Einen eine Verbesserung der Funktion des Brenners und zum Anderen eine Verlängerung der Standzeit der Düse durch eine gute me- dienseitige Kühlung. Channels, such as at the Pilotbrennerdüse (2), it is possible in sufficient Ge ¬ accuracy and surface quality, as they are conven tionally ¬ impossible or very expensive to manufacture. The An ¬ order of an integrated swirler (9) brings on the one hand an improvement in the function of the burner and on the other hand, an extension of the service life of the nozzle by a good media-side cooling.
Des Weiteren kann in der Düse in Nähe zur Brennerspitze ein Sensor (10) zur Temperaturüberwachung angeordnet sein, der sowohl Rückschlüsse auf die thermische Belastung und den Ver¬ schleißzustand des Brenners als auch auf den aktuellen Be¬ triebszustand des Vergasungsreaktors zulässt (Fig 2). Als weiteres Ausführungsbeispiel ist in Fig 3 die Einführung einer Trennwand (12) in den Oxydationsmittelkanal des Haupt¬ brenners gezeigt. Über je einen Zuführungsstutzen im hinteren Brennerbereich wird beiden Kanälen das Medium mengengeregelt zugeführt. Der äußere der beiden Kanäle erhält im Düsenbe- reich eine angepasste Drallvorrichtung (11), die diesem Strom eine drehende Bewegung aufprägt. Der resultieren Winkel des gesamten austretenden Medienstromes zur Brennerachse kann so¬ mit über die Regelung der beiden Teilvolumenströme einge¬ stellt werden. Als Drallvorrichtung kann dabei beispielsweise ein auf der Trennwand befestigtes, spiralförmig geformtesIn the nozzle in proximity to the burner tip Furthermore, a sensor (10) may be arranged for monitoring temperature, which allows both to draw conclusions about the thermal load and the Ver ¬ schleißzustand of the burner as well as on the current Be ¬ operating state of the gasification reactor (Figure 2). As a further embodiment, the introduction of a partition wall (12) in the oxidant channel of the main ¬ burner is shown in FIG. The media is fed volume-controlled to both channels via a feed connection in the rear burner area. The outer of the two channels receives in the nozzle area an adapted swirl device (11), which imparts a rotating movement to this stream. The resulting angle of the total exiting medium flow to the burner axis can thus be set ¬ by means of the control of the two partial volume flows ¬ . As a twisting device can, for example, a fixed on the partition wall, spirally shaped
