Beschreibungdescription
Technisches GebietTechnical area
Die Erfindung betrifft eine Brenneranordnung insbesondere zur Beheizung, Trocknung und/oder Warmhaltung insbesondere von Verteilern einer Stranggießanlage.The invention relates to a burner arrangement, in particular for heating, drying and / or keeping warm in particular of distributors of a continuous casting plant.
Stand der TechnikState of the art
In Schmelzbetrieben, wie beispielsweise in Stahlwerken mit Stranggießanlagen wird das geschmolzene flüssige Metall in der Regel mittels einer Pfanne an den Gießstand einer Stranggießanlage gebracht. Das heiße flüssige Metall wird mittels eines Verteilers, wie beispielsweise einer Verteilerrinne, zwischengepuffert, bevor es in die Kokille der Stranggießanlage einströmt. Der Verteiler dient auch dazu, dass ein laufender Wechsel der Gießpfannen durchgeführt werden kann, somit also ein Sequenzgießen des Metalls durchführbar ist.In smelting operations, such as in steel plants with continuous casting plants, the molten liquid metal is usually brought by means of a pan to the casting stand of a continuous casting plant. The hot liquid metal is buffered by means of a distributor, such as a distributor trough, before it flows into the mold of the continuous caster. The distributor also serves to allow a continuous change of the ladles, so that a sequence casting of the metal is feasible.
Die Verteiler werden in der Regel zyklisch neu zugestellt und vor jeder Sequenz gegebenenfalls neu zwischenrepariert und mit einem Tauchrohr bestückt. Danach wird der Verteiler getrocknet und aufgeheizt. Zur Beheizung wird dabei ein Brenner mit fossilen Brennstoffen, wie mit Erdgas, und mit Sauerstoffträgern, wie beispielsweise mit Luft, betrieben. Dabei werden üblicher Weise im Handel erhältliche Brenner verwendet, die in einen Heizdeckel eingebaut werden. Durch die Verwendung von handelsüblichen Brennern mit Flammenerzeugung wird ein sich schnell bewegendes Abgas erzeugt, das zur Strähnenbildung neigt und insgesamt einen geringen Anteil an Strahlungsenergie aufweist.As a rule, the distributors are cyclically relisted and, if necessary, newly repaired before each sequence and equipped with a dip tube. Thereafter, the manifold is dried and heated. For heating while a burner with fossil fuels, such as natural gas, and with oxygen carriers, such as air, operated. In this case, conventionally commercially available burners are used, which are installed in a heated lid. By using commercially available burners with flame generation, a fast-moving exhaust gas is generated which tends to streak and has a low proportion of radiant energy.
Durch die Flammen werden punktuelle Aufheizungen erzeugt, was zu einer lokalen Überhitzung führen kann, wo die jeweilige Flamme direkt auftrifft und wobei andere Bereiche wiederum eher zu schwach erhitzt werden, wo die Flamme zu weit entfernt ist. Dadurch werden Spannungen im Verteiler verursacht, was zu Rissbildung und somit zum Ausfall der gesamten Anlage führen kann. Wei- terhin ist durch die inhomogene Erwärmung mit der Flamme die Trocknungszeit verlängert, die Standzeit des Verteilers reduziert und gleichzeitig der Energieverbrauch sehr hoch. Auch der Ausstoß an CO2 ist ebenfalls sehr hoch. Auch ist dadurch der Verbrauch an Ausmauerungsmaterial des Verteilers erhöht, weil es bei erhöhter Rissbildung häufiger ersetzt werden muss. Dadurch sind die Kosten für die Energiebereitstellung hoch, was die Anlage weniger wirtschaftlich macht und darüber hinaus ist der Ausstoß des Verbrennungsabgase sehr hoch und insgesamt relativ weniger umweltfreundlich, was in der letzten Zeit im Rahmen der Diskussion um den Treibhauseffekt als besonders nachteilig empfunden wird.The flames produce selective heat, which can lead to localized overheating, where the flame is directly impacted, and other areas tend to be heated too weakly where the flame is too far away. As a result, voltages are caused in the distributor, which can lead to cracking and thus the failure of the entire system. Furthermore, the inhomogeneous heating with the flame extends the drying time, reduces the service life of the distributor and at the same time the energy consumption is very high. The emission of CO 2 is also very high. Also, this increases the consumption of lining material of the distributor because it has to be replaced more often with increased cracking. As a result, the cost of energy supply is high, which makes the system less economical and also the output of the combustion gases is very high and overall relatively less environmentally friendly, which is considered particularly disadvantageous in the recent discussion of the greenhouse effect.

Darstellung der Erfindung, Aufgabe, Lösung, VorteilePresentation of the invention, object, solution, advantages
Aufgabe der Erfindung ist es, eine Brenneranordnung insbesondere zur Behei- zung, Trocknung und/oder Warmhaltung insbesondere von Verteilern einerIt is an object of the invention to provide a burner arrangement, in particular for heating, drying and / or keeping warm, in particular distributors of a
Stranggießanlage zu schaffen, die eine verbesserte Ausnutzung der eingesetz- ten Energie, eine Reduktion des Ausstoßes von CO2 und eine hohe Verfügbarkeit der Anlage erreicht. Weiterhin ist es Aufgabe der Erfindung ein Verfahren zum vorteilhaften Steuern einer Brenneranordnung zu schaffen.Continuous casting plant, the improved utilization of the used Energy, a reduction in the emission of CO 2 and a high availability of the plant achieved. It is another object of the invention to provide a method for advantageously controlling a burner assembly.
Die Aufgabe bezüglich der Brenneranordnung wird gelöst mit einer Brenneran- Ordnung insbesondere zur Beheizung, Trocknung und/oder Warmhaltung insbesondere von einem Verteiler einer Stranggießanlage, mit einer flächigen Anordnung von zumindest einem Brenner, wobei der oder die Brenner als Porenbrenner ausgebildet ist oder sind.The object with regard to the burner arrangement is achieved with a burner arrangement, in particular for heating, drying and / or keeping hot, in particular from a distributor of a continuous casting plant, with a planar arrangement of at least one burner, wherein the burner or burners is or are formed as a pore burner.
Dabei ist es besonders vorteilhaft, wenn der Porenbrenner Porenbrennerseg- mente aufweist. Dabei kann der Porenbrenner ein Segment aufweisen oder eine Mehrzahl von Segmenten, die miteinander verbunden sind oder die zumindest bis auf eine geringe Fuge zwischen den Segmenten benachbart angeordnet sind. Die verbundenen Segmente sind erfindungsgemäß mittels Verbin- dungsmitteln verbunden und/oder derart beispielsweise mittels eines Rahmens gehalten, dass ein einheitlicher Brenner durch die benachbarte Anordnung der Segmente erreicht ist. Bei einem vorteilhaften Ausführungsbeispiel ist es zweckmäßig, wenn die Porenbrennersegmente des Porenbrenners flächig in benachbarten Reihen angeordnet sind.It is particularly advantageous if the pore burner has pore burner segments. In this case, the pore burner may have a segment or a plurality of segments which are connected to one another or which are arranged adjacent to one another at least to a small gap between the segments. According to the invention, the connected segments are connected by means of connecting means and / or held for example by means of a frame such that a uniform burner is achieved by the adjacent arrangement of the segments. In an advantageous embodiment, it is expedient if the pore burner segments of the pore burner are arranged flat in adjacent rows.
Zur Versorgung mit Brennstoff und mit einem Sauerstoffträger ist es zweckmäßig, wenn die Porenbrennersegmente jeweils mittels Zuleitungen mit Brennstoff und/oder mit einem Sauerstoffträger versorgt werden. Dabei ist es vorteilhaft, wenn zumindest einzelne der Zuleitungen über eine gemeinsame Versorgungs- leitung mit Brennstoff und/oder mit einem Sauerstoffträger versorgt werden. Auch ist es bei einem weiteren Ausführungsbeispiel vorteilhaft, wenn ein Gebläse zur Versorgung des Sauerstoffträgers über die Zuleitungen vorgesehen ist. Dadurch wird mittels des Gebläses ein Sauerstoffträger, wie beispielsweise Luft, durch die Zuleitungen zu den Segmenten gefördert. Zur Handhabung der Brenneranordnung ist es vorteilhaft, wenn die Porenbren- neranordnung von einer verschwenkbaren Halterung oder einem Schwenkarm gehalten sind, der mittels eines Gelenks verschwenkbar ausgebildet ist. Dabei kann es bei einem weiteren Ausführungsbeispiel zweckmäßig sein, wenn das Gebläse ebenfalls von der Halterung oder dem Schwenkarm gehalten ist, und somit auch das Gebläse verschwenkbar angeordnet ist.For supplying fuel and with an oxygen carrier, it is expedient if the pore burner segments are supplied in each case by means of feed lines with fuel and / or with an oxygen carrier. It is advantageous if at least some of the supply lines are supplied via a common supply line with fuel and / or with an oxygen carrier. It is also advantageous in a further embodiment, when a blower for supplying the oxygen carrier is provided via the supply lines. As a result, an oxygen carrier, such as air, is conveyed through the supply lines to the segments by means of the blower. To handle the burner assembly, it is advantageous if the Porenbren- neranordnung are held by a pivotable holder or a pivot arm, which is designed to be pivotable by means of a hinge. It may be useful in another embodiment, when the blower is also held by the bracket or the pivot arm, and thus the fan is pivotally mounted.
Die Aufgabe hinsichtlich des Verfahrens wird gelöst durch ein Verfahren zum Steuern einer Brenneranordnung, wobei in Abhängigkeit der gewünschten Heizungsintensität bzw. Heizleistung Porenbrennersegmente zugeschaltet und/oder abgeschaltet werden. Dabei ist es zweckmäßig, wenn Segmente zu- oder abgeschaltet werden, die zumindest abwechselnd in Reihen oder die beispielsweise in einem Schachbrettmuster angeordnet sind.The object with regard to the method is achieved by a method for controlling a burner arrangement, wherein pore burner segments are switched on and / or switched off as a function of the desired heating intensity or heating power. It is expedient if segments are switched on or off, which are arranged at least alternately in rows or, for example, in a checkerboard pattern.

Fig. 2 eine Aufsicht einer Brenneranordnung nach Figur 1.2 shows a plan view of a burner arrangement according to FIG. 1.
Bevorzugte Ausführung der Erfindung Die Figur 1 zeigt eine Ansicht einer Brenneranordnung 1 insbesondere zur Beheizung, Trocknung und/oder zur Warmhaltung von Verteilern insbesondere von einer Stranggießanlage. Die Brenneranordnung 1 weist dabei einen Bren- ner 2 auf, der an einer Halterung 3 aufgenommen ist und der mittels der Halte- rung 3 mit Schwenklager 4 verschwenkbar ausgebildet ist. Die Halterung bildet also einen Schwenkarm. Dabei kann der Brenner über dem Verteiler 5 liegen, wie in einer Heizposition 8, und diesen Beheizen oder der Brenner kann nach oben geklappt werden, in eine Parkposition 9, so dass er im Wesentlichen senkrecht steht und der Verteiler für weitere Arbeiten im Wesentlichen frei zugänglich ist. Zwischen diesen Positionen ist der Schwenkarm beispielsweise mittels einer Hydraulik oder mittels Druckluft betätig verschwenkbar.Preferred embodiment of the invention FIG. 1 shows a view of a burner arrangement 1, in particular for heating, drying and / or keeping warm the distributors, in particular of a continuous casting plant. In this case, the burner arrangement 1 has a burner 2, which is accommodated on a holder 3 and which is designed to be pivotable by means of the holder 3 with a pivot bearing 4. The holder thus forms a pivoting arm. In this case, the burner can lie above the distributor 5, as in a heating position 8, and this heating or the burner can be folded upwards, into a parking position 9 so that it is substantially vertical and the distributor is essentially freely accessible for further work is. Between these positions, the pivot arm is actuated, for example, by means of a hydraulic or by means of compressed air.
Der Brenner 2 ist dabei erfindungsgemäß als Porenbrenner 10 ausgebildet. Der Porenbrenner 10 weist dabei die vorteilhafte Eigenschaft auf, dass er als Gasbrenner eine Verbrennung eines Gas-Luft-Gemischs in einer porösen Struktur oder Zelle erlaubt, die quasi oder völlig ohne die Ausbildung einer offenen Flamme auskommt. Als Resultat wird eine flammenlose, volumetrische Verbrennung des Gas-Luft-Gemischs erreicht. Dabei wird somit eine Verbren- nung in der porösen Struktur erreicht, so dass nach dem Einleiten des Gas-Luft- Gemischs als Reaktionsprodukt ein Abgasstrom ausgangsseitig erzeugt wird.The burner 2 is formed according to the invention as a pore burner 10. The pore burner 10 has the advantageous property that it allows combustion of a gas-air mixture in a porous structure or cell as a gas burner, which manages quasi or completely without the formation of an open flame. As a result, a flameless, volumetric combustion of the gas-air mixture is achieved. In this case, a combustion in the porous structure is thus achieved, so that after the introduction of the gas-air mixture as the reaction product, an exhaust gas flow is generated on the output side.
Der Sauerstoffträger, wie beispielsweise die Luft, wird beispielsweise mittels eines Gebläses 6 in den Porenbrenner 10 eingeblasen. Dabei wird der Sauer- stoffträger durch das Gebläse angesaugt und über Versorgungskanäle oder Versorgungszuleitungen 7 dem als Porenbrenner 10 ausgebildeten Brenner zugeführt.The oxygen carrier, such as the air, for example, is blown by means of a blower 6 in the pore burner 10. In this case, the oxygen carrier is sucked in by the blower and fed via supply channels or supply feed lines 7 to the burner designed as a pore burner 10.
Der in Figur 2 dargestellte Porenbrenner 10 ist vorteilhaft aus mehreren Seg- menten des Porenbrenners zusammengesetzt. Die einzelnen SegmenteThe pore burner 10 shown in FIG. 2 is advantageously composed of several segments of the pore burner. The individual segments
11 ,12,13 sind dazu im Wesentlichen flächig angeordnet und weisen eine Ver- bindung zu zumindest einer Zuleitung 14,15 auf, mittels welcher der Brennstoff und/oder der Sauerstoffträger dem jeweiligen Segment zugeführt wird. Dabei kann, wie oben dargestellt, die Luft oder der Sauerstoffträger über ein Gebläse in die Porenbrennersegmente eingebracht werden. Auch kann bei einem anderen Ausführungsbeispiel eine Zuleitung für ein Brennstoff-Luft-Gemisch vorge- sehen sein.11, 12, 13 are arranged essentially flat and have a Binding to at least one supply line 14,15, by means of which the fuel and / or the oxygen carrier is supplied to the respective segment. In this case, as shown above, the air or the oxygen carrier can be introduced via a blower in the pore burner segments. Also, in another embodiment, a supply line for a fuel-air mixture can be provided.
Die flächig angeordneten Segmente sind dazu vorteilhaft mit geringem Fugenabstand nebeneinander angeordnet, so dass eine mehrreihige flächige Anordnung der Porenbrennersegmente vorgesehen ist. Dazu können die Porenbren- nersegmente mittels Haltemitteln, wie beispielsweise in einem Halterahmen, gehalten sein, welcher mit dem Schwenkarm verbunden ist, so dass die flächige Anordnung der Porenbrennersegmente mit dem Schwenkarm gemeinsam verschwenkt werden kann.The flat arranged segments are advantageously arranged side by side with a small joint spacing, so that a multi-row planar arrangement of the pore burner segments is provided. For this purpose, the pore burner segments can be held by means of holding means, such as in a holding frame, which is connected to the swivel arm, so that the planar arrangement of the pore burner segments can be pivoted together with the swivel arm.
Der Porenbrenner erzeugt einen heißen Abgasstrom und dazu auch Wärmestrahlung, welche auf den Verteiler gerichtet werden, um diesen zu heizen, zu trocknen, zu erwärmen oder auf der Temperatur zu temperieren. Dabei tritt das heiße Abgas in den Innenraum oder die Oberfläche des Verteilers auf, was eine homogene Temperaturverteilung bewirkt und somit einer Strähnenbildung ent- gegenwirkt. Dadurch, dass aber auch ein hoher Anteil der Energie in Strahlung umgesetzt wird, kann der Verteiler ebenfalls sehr effektiv beheizt werden.The pore burner generates a hot exhaust gas stream and, in addition, heat radiation, which are directed onto the distributor in order to heat it, to dry it, to heat it or to temper it at the temperature. In this case, the hot exhaust gas occurs in the interior or the surface of the distributor, which causes a homogeneous temperature distribution and thus counteracts a stratification. Due to the fact that even a high proportion of the energy is converted into radiation, the distributor can also be heated very effectively.
Besonders vorteilhaft ist die Ausbildung des Porenbrenners als im Wesentlichen flächige Anordnung, wobei die Anordnung aus einzelnen Segmenten von Porenbrennern zusammengesetzt ist. Dadurch kann vorteilhaft gesteuert vorgegangen werden, dass einzelne Segmente oder Reihen von Segmenten unabhängig von einander zu- oder abgeschaltet werden oder einzelne Segmente unabhängig voneinander zu- oder abgeschaltet werden.Particularly advantageous is the formation of the pore burner as a substantially planar arrangement, wherein the arrangement is composed of individual segments of pore burners. As a result, it can be advantageously controlled that individual segments or rows of segments are switched on or off independently of one another or individual segments are switched on or off independently of one another.
Dabei können je nach vorzunehmender Heizungsintensität bzw. Heizleistung alle Porenbrennersegmente zugeschaltet werden oder einzelne der Segmente abgeschaltet werden. Vorteilhaft kann es sein, wenn Segmente zu- oder abgeschaltet werden, die zumindest abwechselnd in Zeilen verteilt sind. Auch kann es vorteilhaft sein, wenn Segmente abwechselnd zu- oder abgeschaltet werden, die schachbrettartig angeordnet sind, so dass nur ein Bruchteil der Segmente betrieben werden. Depending on the heating intensity or heat output to be carried out, all pore burner segments can be switched on or individual segments be switched off. It can be advantageous if segments are switched on or off, which are at least alternately distributed in rows. It may also be advantageous if segments are alternately switched on or off, which are arranged like a checkerboard, so that only a fraction of the segments are operated.
