Description
Die Neuerung betrifft eine Reaktorwand nach dem Oberbegriff des ersten Patentanspruches. Die Neuerung ist einsetzbar für Flugstromvergaser zur Vergasung von konventionellen Brennstoffen sowie von Rest- und Abfallstoffen.The innovation concerns a reactor wall according to the preamble of the first claim. The innovation is can be used for Traction current gasifier for the gasification of conventional fuels as well as residues and waste materials.
Unter Brenn-, Rest- und Abfallstoffen sind solche mit einem Aschegehalt > 0,3 Ma% wie Braun- oder Steinkohlen, Öle, Teere und Schlämme sowie Reste oder Abfälle von chemischen Prozessen sowie der Papier- und Zellstoffindustrie, wie beispielsweise Schwarzlauge aus dem Kraftprozeß, sowie feste und flüssige Fraktionen aus der Abfall- und Recyclingwirtschaft, wie Altöle, PCB-haltige Öle, Plaste- und Hausmüllfraktionen oder ihre Aufbereitungsprodukte sowie Produkte der Erdölverarbeitung wie Schweröle oder Petrolkokse zu verstehen.Among fuels, residues and waste materials are those with an ash content> 0.3 Ma% such as brown or hard coal, oils, tars and sludges as well as residues or waste chemical processes as well as the pulp and paper industry, such as black liquor from the power process, as well solid and liquid Fractions from the waste and recycling industry, such as waste oils, PCB-containing oils, plastics and household waste fractions or their processing products and petroleum processing products like heavy oils or To understand petroleum coke.
In der Technik der Gaserzeugung ist die autotherme Flugstromvergasung von festen, flüssigen und gasförmigen brennbaren Stoffen langjährig bekannt. Das Verhältnis von Brennstoff zu sauerstoffhaltigen Vergasungsmitteln wird dabei so gewählt, daß aus Gründen der Synthesegasqualität höhere Kahlenstoffverbindungen zu Synthesegaskomponenten wie CO und H2 aufgespalten werden und die anorganischen Bestandteile als schmelzflüssige Schlacke ausgetragen werden (Ch. Higman, "Gasification", Elsevier 2003, Seite 109).In the technology of gas generation is the autothermal entrained-flow gasification of solid, liquid and gaseous combustible Long-lasting fabrics known. The relationship from fuel to oxygen-containing gasification agents chosen so that for the sake of Synthesis gas quality higher bare metal compounds split into synthesis gas components such as CO and H2 and the inorganic constituents are discharged as molten slag (Ch. Higman, "Gasification", Elsevier 2003, Page 109).
Nach verschiedenen in der Technik eingeführten Systemen können dabei Vergasungsgas und der schmelzflüssige anorganische Anteil als Schlacke, getrennt oder gemeinsam aus dem Reaktionsraum der Vergasungsvorrichtung ausgetragen werden, siehe DE 19718131A1.After various in engineering introduced Systems can thereby gasification gas and the molten inorganic portion as Slag, separately or together from the reaction chamber of the gasification device are carried out, see DE 19718131A1.
Für
die innere Begrenzung der Reaktionsraumkontur des Vergasungsreaktors
werden sowohl mit feuerfester Auskleidung versehene oder gekühlte Systeme
eingeführt
(
Mit feuerfester Auskleidung versehene Vergasungssysteme haben den Vorteil geringer Wärmeverluste und bieten deshalb eine energetische effektive Umsetzung der zugeführten Brennstoffe. Sie sind allerdings nur für aschefreie Brennstoffe einsetzbar, da die bei der Flugstromvergasung an der inneren Oberfläche des Reaktorraumes abfließende flüssige Schlacke die feuerfeste Auskleidung auflöst und deshalb nur sehr begrenzte Reisezeiten bis zu einer kostenintensiven Neuzustellung erlaubt.Provided with fireproof lining Gasification systems have the advantage of low heat loss and therefore offer an energetic effective implementation of the supplied fuels. However, you are only for Ash-free fuels can be used, since they are used in entrained-flow gasification on the inner surface of the reactor space flowing out liquid slag the refractory lining dissolves and therefore only very limited travel times to an expensive one Redelivery allowed.
Um diesen Nachteil bei aschehaltigen Brennstoffen
zu beheben, wurden deshalb gekühlte Systeme
nach dem Prinzip ein Membranwand geschaffen, wie es
Ein Nachteil besteht allerdings im
komplizierten Aufbau der Reaktorwand, was zu erheblichen Problemen
bei der Herstellung und im Betrieb führen kann. So besteht beispielsweise
die Reaktorwand aus einem drucklosen Wassermantel, dem Druckmantel,
der auf der Innenseite korrosionsgeschützt ist sowie dem Kühlschirm,
der wie eine im Kesselbau übliche
Membranwand aus gasdicht verschweißten, wasserdurchströmten Kühlrohren
besteht, die bestiftet und mit einer dünnen SiC-Schicht belegt sind
(
Diese Aufgabe wird durch Vorrichtungen nach den Merkmalen des ersten Anspruches gelöst. Unteransprüche geben weitere vorteilhafte Ausführungen der Neuerung wieder.This task is accomplished by devices solved the features of the first claim. Give subclaims further advantageous designs the innovation again.
Die Reaktorwand für einen Flugstromvergaser für kohlenstoffhaltige Brenn-, Rest- und Abfallstoffe mit einem sauerstoffhaltigen Oxidationsmittel und einem Vergasungsraum für Drücke zwischen Umgebungsdruck und 100 bar, bei dem die Reaktionsraumkontur durch ein Kühlsystem begrenzt wird, wobei der Druck im Kühlsystem immer höher gehalten wird, als der Druck im Reaktionsraum zeichnet sich dadurch aus, daß Kühlkanäle auf Innenseite des Druckmantels aufgeschweißt sind oder eine profilierte Kühlwand mit dem Druckmantel einen Ringspalt bildet. Sowohl die Kühlkanäle als auch der Ringspalt sind wasserdurchströmt. Die Auslegung erfolgt so, daß die Druckdifferenz zwischen Kühlkanälen oder Ringspalt zum Vergasungsraum durch die auf den Druckmantel aufgeschweißten Kühlkanäle oder der profilierten Kühlwand aufgenommen werden. Der Druck in den Kühlkanälen oder dem Ringspalt liegt 1 bis 2 bar über dem Druck im Vergasungsraum. Diese Druckdifferenz soll bewirken, daß im Falle eines Lecks in keinem Fall Vergasungsgas aus dem Vergasungsraum in die Kühlkanäle oder den Ringspalt eindringen kann, sondern daß in einem solchen Fall immer Kühlwasser in den Vergasungsraum übertritt.The reactor wall for an entrained flow gasifier for carbonaceous Fuels, residues and waste materials with an oxygen-containing oxidizing agent and a gasification room for pressures between ambient pressure and 100 bar at which the reaction chamber contour through a cooling system is limited, the pressure in the cooling system being kept higher and higher is characterized as the pressure in the reaction space that cooling channels on the inside of the pressure jacket welded on are or a profiled cooling wall forms an annular gap with the pressure jacket. Both the cooling channels as well water flows through the annular gap. The design is such that the pressure difference between cooling channels or annular gap to the gasification chamber through the cooling channels welded onto the pressure jacket or the profiled cooling wall be included. The pressure in the cooling channels or the annular gap is 1 to 2 bar above the pressure in the gasification room. This pressure difference should that in In the event of a leak, in no case gasification gas from the gasification room into the cooling channels or can penetrate the annular gap, but that in such a case always cooling water enters the gasification room.
Die Vorrichtungen sind von außen nach innen wie folgt aufgebaut: Druckmantel, Kühlkanäle oder Kühlspalt, feuerfeste Schutzschicht aus beispielsweise SiC-Stampfmasse, Schlackepelz aus erstarrter Schlacke, Film flüssiger Schlacke.The devices are from the outside internally constructed as follows: pressure jacket, cooling channels or cooling gap, fire-proof protective layer from, for example, SiC ramming mass, slag fur from solidified Slag, film more fluid Slag.
Vorteilhaft für die Neuerung ist, daß Druck und Temperatur in den Kühlkanälen oder dem Ringspalt so geregelt werden, daß sich der Zustand oberhalb oder unterhalb des Siedepunktes des Kühlwassers befinden kann.The advantage of the innovation is that pressure and Temperature in the cooling channels or the annular gap should be regulated so that the state above or below the boiling point of the cooling water.
Neuerungswesentlich ist es, daß die feuerfeste Schutzschicht auf den Kühlkanälen oder der perforierten Kühlwand durch aufgeschweißte stiftähnliche oder gespreizte Anker befestigt wird. Die Vorrichtungen eignen sich für die Vergasung von Brenn-, Rest- und Abfallstoffen unterschiedlichen Aschegehaltes sowie für die simultane Vergasung von kohlenwasserstoffhaltigen Gasen, Flüssigkeiten, und kohlenstoffhaltigen Feststoffen. Es ist vorgesehen, die Reaktionsraumkontur für den Vergasungsprozeß durch eine Schicht aus erstarrter Schlacke zu begrenzen. Durch die intensive Kühlung wird die im Vergasungsprozeß bei Temperaturen zwischen 900 und 1600°C verflüssigte Schlacke zur Erstarrung gebracht, so daß sich eine feste Schlackeschicht als thermische Isolierschicht bildet.It is essential for innovation that the refractory Protective layer on the cooling channels or the perforated cooling wall through welded on pen-like or spread anchor is attached. The devices are suitable for the Gasification of fuels, residues and waste materials with different ash contents also for the simultaneous gasification of hydrocarbon-containing gases, liquids, and carbonaceous solids. It is contemplated the reaction space contour for the Gasification process through to delimit a layer of solidified slag. Because of the intense cooling will the in the gasification process Temperatures between 900 and 1600 ° C liquefied slag for solidification brought so that forms a solid slag layer as a thermal insulation layer.
Eine Ausführungsvariante besteht darin, die Kühlwand als auf den Druckmantel aufgeschweißte kühlwasserdurchströmte Halbrohre auszubilden. Zur besonderen Befestigung der feuerfesten Stampfmasse ist es vorteilhaft, auf die Halbrohre Anker aufzubringen. Die Form der Halbrohre muß auch nicht halbrund ausgeführt sein. Vorteilhafterweise können die Rohre auch eine elliptische Form aufweisen.One variant is the cooling wall as half-pipes through which cooling water flows and welded onto the pressure jacket train. For special attachment of the refractory ramming compound it is advantageous to apply anchors to the half-tubes. Form the half pipe must also not semi-circular his. Advantageously, the Pipes also have an elliptical shape.
Am Folgenden wird die Neuerung an drei Figuren erläutert.The following is the innovation three figures explained.
