Keramische Beschichtung von VergasungsbrennerteilenCeramic coating of gasification burner parts
Die Erfindung betrifft einen Brenner für einen mit festem o- der flüssigen Brennstoff befeuerten Reaktor aufweisend einen Zuführungskanal für ein freien Sauerstoff enthaltendes Oxida- tionsmittel und einen Zuführungskanal für den Brennstoff.The invention relates to a burner for a solid or the liquid fuel-fired reactor comprising a supply channel for a free oxygen-containing oxidant tion medium and a supply channel for the fuel.
Vergasungsstoffbrenner für Flugstromvergaser sind im Bereich der direkt an den Vergasungsraum angrenzenden Brennerteile einer starken Wärmeeinwirkung (> 10000C) ausgesetzt, welche die Lebensdauer der Bauteile negativ beeinflussen und einen höheren Wartungsaufwand verursachen kann. Weitere die Stand- zeit der direkt an den Vergasungsraum angrenzenden Brennerteile beeinflussende Faktoren sind die bei der Vergasungsreaktion entstehenden korrosiven Reaktionsprodukte wie z.B. Wasserstoff, Chlorverbindungen etc. Neben diesem hohen Wärmeeintrag reaktionsraumseitig stellt auch die Umlenkung der SauerstoffZuführung in den Brennerkanal, das Vorbeiströmen des Sauerstoffes an scharfkantigen Konturen sowie mitgeführte feste Partikel und das damit verbundene Risiko eines Sauerstoff-Metallbrandes ein potentielles Risiko für die Standzeit des Brenners dar. Die dabei auf- tretenden Wärmeeinträge müssen in ausreichender Höhe abgeführt werden bzw. muss die Temperatur der Metalloberfläche in geeigneter Weise begrenzt werden.Gasifier burners for entrained-flow carburettors are exposed to a high level of heat (> 1000 ° C) in the area of the burner parts directly adjacent to the gasification chamber, which can adversely affect the service life of the components and cause higher maintenance. Other factors influencing the service life of the burner parts directly adjacent to the gasification chamber are the corrosive reaction products such as hydrogen, chlorine compounds, etc. In addition to this high heat input on the reaction chamber side, the diversion of the oxygen supply into the burner channel also precludes the oxygen from reaching sharp edges Contours and entrained solid particles and the associated risk of an oxygen-metal fire, a potential risk for the service life of the burner. The thereby occurring heat inputs must be dissipated in sufficient height or the temperature of the metal surface must be suitably limited.
Die oben aufgeführten Belastungen der direkt an den Verga- sungsraum angrenzenden Brennerteile werden bis jetzt durch eine intensive Kühlung über verschiedene Kühlkreisläufe mittels Kühlwasser (Kühlkammern) bzw. betriebsbedingt durch gasförmige Spül- und Vergasungsmedien minimiert. Zusätzlich kommen hitze- und korrosionsbeständige Werkstoffe (z.B. Nickel- basislegierungen) zum Einsatz. Trotz dieser Maßnahmen kann nicht ausgeschlossen werden, dass direkt an den Vergasungsraum angrenzende Brennerteile aufgrund der hohen Temperatur- und Korrosionsbelastung geschädigt werden und entsprechend verkürzte Einsatzzeiten in Kauf genommen werden müssen.The above-mentioned loads on the burner parts directly adjacent to the gasification space are hitherto minimized by intensive cooling via various cooling circuits by means of cooling water (cooling chambers) or by gaseous rinsing and gasification media as a result of operation. In addition, heat and corrosion resistant materials (eg nickel based alloys) are used. Despite these measures, it can not be ruled out that burner parts directly adjacent to the gasification chamber can not be excluded due to the high temperature and corrosion stress are damaged and correspondingly shorter operating times must be taken into account.
Um der Gefahr eines Sauerstoff-Metallbrandes vorzubeugen, wird bisher die Sauerstofftemperatur auf möglichst niedrige Werte begrenzt, was die Effektivität des Verfahrens verringert und zu geringeren Wirkungsgraden führt.In order to prevent the risk of an oxygen-metal fire, the oxygen temperature has so far been limited to the lowest possible values, which reduces the effectiveness of the process and leads to lower efficiencies.
Der Erfindung liegt das Problem zugrunde, einen Brenner, ins- besondere Vergasungsbrenner für die Flugstromvergasung, derart weiterzubilden, dass die beschriebenen Nachteile vermieden werden.The invention is based on the problem of developing a burner, in particular gasification burner for the entrained flow gasification, in such a way that the described disadvantages are avoided.
Das Problem wird bei einem gattungsgemäßen Gegenstand durch die Merkmale des kennzeichnenden Teils des Anspruchs 1 gelöst .The problem is solved in a generic object by the features of the characterizing part of claim 1.
Um die durch hohen Strahlungsanteil verursachte hohe Oberflächentemperatur der Brennerkühlteile zu reduzieren, wird eine keramische Schutzschicht aufgetragen. Die Schutzschicht reduziert die Oberflächentemperatur der metallischen Bauteile auf weit unter 10000C und führt somit zu einer verringerten Temperaturdifferenz zwischen Oberflächen- und Kühlwassertemperatur und vergleichsweise geringen Spannungszuständen . Als Schutzschichtmaterial können verschiedene keramische Materialien eingesetzt werden. Besonders vorteilhaft erweist sich dabei die Verwendung von Zirkon-/Yttriumoxid-Gemischen . Diese Schutzschicht wird auf die Brennerkühlteile (Pilotbrenner, mittleres und äußeres Kühlteil) aufgebracht. Durch eine spe- zielle mehrschichtige Auftragstechnologie beim Plasmaspritzen erfolgt die Anpassung der thermischen Ausdehnungskoeffizienten des metallischen Grundmaterials und der keramischen Deckschicht. Somit wird eine gute Haftung erreicht und ein Abplatzen der Schutzschicht verhindert.In order to reduce the high surface temperature of the burner cooling parts caused by the high proportion of radiation, a ceramic protective layer is applied. The protective layer reduces the surface temperature of the metallic components to well below 1000 0 C and thus leads to a reduced temperature difference between surface and cooling water temperature and relatively low voltage states. As a protective layer material, various ceramic materials can be used. Particularly advantageous is the use of zirconium / yttrium oxide mixtures. This protective layer is applied to the burner cooling parts (pilot burner, middle and outer cooling part). By means of a special multi-layer application technology for plasma spraying, the adaptation of the thermal expansion coefficients of the metallic base material and the ceramic cover layer takes place. Thus, a good adhesion is achieved and prevents chipping of the protective layer.
Eine weitere Verbesserung der Standzeiten des Brenners kann durch die Verwendung von Metallen sehr guter Wärmeleiteigenschaften wie z.B. kupferhaltigen Nickelbasislegierungen im Sauerstoffkanal und / oder an den hoch belasteten Teilen am Brennermund erreicht werden. Neben seiner guten Wärmeleitung besitzen kupferhaltige Nickelbasislegierungen wie z. B. Monel 400 auch ausreichend hohe Festigkeitseigenschaften und eine hohe Temperaturbeständigkeit, was für die druckbelastetenA further improvement of the service life of the burner can be achieved by the use of metals of very good thermal conductivity, such as copper-containing nickel-based alloys Oxygen channel and / or be achieved at the highly loaded parts at the burner mouth. In addition to its good heat conductivity have copper-containing nickel-based alloys such. B. Monel 400 also sufficiently high strength properties and high temperature resistance, which is the pressure-loaded
Brennermundteile wichtig ist. Durch den Einsatz von Metallen mit sehr guter Wärmeleit- und hohen Festigkeitseigenschaften wird eine höhere Medientemperatur im Zuführungskanal für den freien Sauerstoff ermöglicht.Burner mouthpieces is important. The use of metals with very good thermal conductivity and high strength properties enables a higher medium temperature in the supply channel for the free oxygen.
Die keramische Beschichtung der Brennerkühlteile verbessert die Lebensdauer des Brenners und erhöht somit Anlagenverfügbarkeit bei gleichzeitiger Minimierung des Wartungsaufwandes. Zusätzlich können kostengünstigere metallische Werkstoffe eingesetzt werden, da die keramische Schutzschicht über hervorragende Dämmeigenschaften verfügt.The ceramic coating of the burner cooling parts improves the life of the burner and thus increases system availability while minimizing maintenance. In addition, more cost-effective metallic materials can be used, since the ceramic protective layer has excellent insulating properties.
Eine weitere Standzeiterhöhung ist durch den Einsatz von gut Wärme leitenden Materialien, wie Monel 400 an den gekühlten Brennermundteilen zu erreichen. Im Falle der Verwendung von sehr gut wärmeleitfähigen Metallen, wie z. B. des unter der Marke vertriebenen Monel 400 kann eine höhere Sauerstofftemperatur im Brenner zugelassen werden und somit eine Erhöhung des Vergasungswirkungsgrades erreicht werden bzw. eine Standzeitverbesserung durch Aus- Schluss von Sauerstoff-Metallbrand bewirkt werden.A further increase in service life can be achieved through the use of highly heat-conductive materials, such as Monel 400, on the cooled burner manifolds. In the case of the use of very good thermal conductivity metals, such. As the marketed under the brand Monel 400 can be allowed a higher oxygen temperature in the burner and thus an increase in the gasification efficiency can be achieved or a service life improvement by eliminating oxygen metal firing are effected.
