Abstract

The invention relates to a method of hot-repairing the heating flues of a coke-oven battery according to which the completed sections of a heating flue still under construction are heated by means of a heated gas. As heated gas the air usually provided for combustion in heating flues during coking operations is used. This air is guided through the flow paths provided for in the coke-oven battery for combustion air and waste gases as well as through the regenerator, heated as it passes through said paths and then guided through the heating flues to be repaired. The completed section of the heating flue is separated from the part still to be constructed by an air-reversion device.

Description

Verfahren zur Heißreparatur der Heizzuge einer Koksofenbatterie und Vorrichtung zum Durchfuhren dieses VerfahrensProcess for the hot repair of the heating trains of a coke oven battery and device for carrying out this process
Die Erfindung betrifft ein Verfahren und eine Vorrichtung zur Heißreparatur der Heizzuge einer Koksofenbatterie gemäß dem Oberbegriff des Anspruchs 1 bzw. des Anspruchs 5.The invention relates to a method and a device for hot repairing the heating cables of a coke oven battery according to the preamble of claim 1 and claim 5.
Aus der EP 0 421 174 Bl ist es bekannt, daß bereits wahrend des Hochmauerns der Heizzuge eine Erwärmung der schon fertiggestellten Abschnitte des jeweiligen Heizzuges bis auf eine Temperatur von ca. 250°C mittels erhitzter Luft erfolgt. Die Luft wird mittels eines Kompressors durch eine Auf- heizrohrschlange in die Heizzuge eingeblasen und verlaßt dieselben über einen Kamin an ihrem jeweiligen oberen Aufmauerungsende. Die für das Verfahren erforderliche Aufheizung der Luft erfolgt im indirekten Warmetausch mit den heißen Teilen der Koksofenbatterie. Dabei wird die Aufheiz- rohrschlange entweder oberhalb der Regeneratorgitterung im Regenerator des Koksofens oder auf der Ofensohle eingebaut.From EP 0 421 174 B1 it is known that already during the building up of the heating trains the already completed sections of the respective heating trains are heated to a temperature of about 250 ° C. by means of heated air. The air is blown into the heating cables by means of a compressor through a heating pipe coil and leaves them via a chimney at their respective upper end of the wall. The heating of the air required for the process takes place in indirect heat exchange with the hot parts of the coke oven battery. The heating coil is installed either above the regenerator grille in the regenerator of the coke oven or on the bottom of the oven.
Dieses Verfahren ist mit einem hohen Installationsaufwand an Rohr- und Leitungsmaterial verbunden. Außerdem muß ein Luft- kompressor installiert werden um die Luft durch die Rohrwege und die Heizzuge zu drucken. Der verfahrenstechnische Aufwand zum Aufheizen der neu aufgemauerten Heizzuge im Ver- gleich zu der nur kurzen erforderlichen Aufheizzeit ist sehr hoch.This process is associated with a high installation effort for pipe and line material. An air compressor must also be installed to push the air through the pipe paths and the heating cables. The procedural effort for heating the newly built-up heating elements in the right at the short heating-up time required is very high.
Der Erfindung liegt die Aufgabe zugrunde, das Verfahren zum Aufheizen der Heizzuge dahingehend zu verbessern, daß bei vereinfachter Technik zufriedenstellende Aufheizeigenschaf- ten erzielt werden.The object of the invention is to improve the method for heating the heating cables in such a way that satisfactory heating properties are achieved with simplified technology.
Diese Aufgabe wird hinsichtlich des Verfahrens durch die Merkmale des Anspruchs 1 sowie hinsichtlich der Vorrichtung durch den Anspruch 6 gelost.This object is achieved with regard to the method by the features of claim 1 and with regard to the device by claim 6.
Weiterbildungen sind in den Unteranspruchen aufgeführt.Further training is listed in the subclaims.
Erfindungsgemaß erfolgt wahrend des Hochmauerns der Heizzuge eine Erwärmung der schon fertiggestellten Abschnitte des jeweiligen Heizzuges z. B. bis auf eine Temperatur von ca. 250°C mittels ganz normaler Verbrennungsluft, die über den Regenerator des Koksofens vorgewärmt wird, wobei die in der Koksofenbatterie vorhandenen Fließwege für Verbrennungsluft und Abgase über den Regenerator benutzt werden. Zu diesem Zweck wird bei Ofen mit Zwillmgsheizzugen eine beim Aufmauern mitwandernde Luftumkehrvorrichtung in den Fließweg eingebaut. Diese Luftumkehrvorrichtung besteht zum einen an- sich aus bekannten Abdeckplatten, die ein Hineinfallen von Mörtel, Schmutz oder Sonstigem wahrend des Heizzug auerns einschranken, und zum anderen aus mindestens einem Luftuber- leitrohr, das die zwischen mindestens zwei Heizzugen liegende Binderwand umgeht im Bereich seiner Mundungsenden die Ab- deckplatten durchbricht und die mindestens zwei Heizzuge so fluidisch verbindet. In einem Luftuberleitrohr wird - vorzugsweise - ein Schieber zum Regulieren des Durchflusses der Verbrennungsluft eingebaut.According to the invention, heating of the already completed sections of the respective heating train takes place during the bricking up of the heating trains. B. up to a temperature of about 250 ° C by means of normal combustion air, which is preheated via the regenerator of the coke oven, the existing flow paths in the coke oven battery for combustion air and exhaust gases are used via the regenerator. For this purpose, in the case of furnaces with twin heating trains, an air reversing device that moves along with the masonry is installed in the flow path. This air reversing device consists, on the one hand, of known cover plates, which prevent mortar, dirt or other things from falling in during the heating pass, and, on the other hand, of at least one air transfer pipe which bypasses the binder wall lying between at least two heating passes in the region of its mouth ends the cover plates breaks through and fluidly connects the at least two heating cables. A slider for regulating the flow of the combustion air is preferably installed in an air supply tube.
Wahrend des Aufmauerns wird über den Regenerator des Koks- ofens den bereits aufgemauerten Teilen der Heizzuge vorgeheizte Luft zugeführt. Diese Luft wird durch den bereits aufgemauerten Heizzugteil und über die Luftumkehrvorrichtung in einen abfallenden Heizzugteil und wieder in Richtung des Regenerators gezogen. Vom Regenerator wird die Luft über den Rauchgaskanal zum Kamin gezogen und tritt dann in die Atmosphäre aus .During the masonry, the regenerator of the coke oven preheated air to the already bricked up parts of the heating trains. This air is drawn through the already built-up heating element and via the air reversing device into a falling heating element and back towards the regenerator. The air is drawn from the regenerator through the flue gas duct to the chimney and then escapes into the atmosphere.
Die Verbrennungsgaszufuhr zu den in Reparatur befindlichen Heizzugen bleibt unterbrochen, so daß über den Fließweg der Beheizungsmedien (Luft und Gas) eines Heizzuges lediglich die Verbrennungsluft durch den Regenerator strömt eine bestimmte Wärmemenge aufnimmt und diese an die aufzuheizenden neuerrichteten Heizzuge wieder abgibt. Die Verbrennungsluft wird als Warmetragermedium benutzt. Auf diese Weise wird ein einfaches und energiegunstiges Aufheizen des frisch aufgemauerten Mauerwerks erreicht.The combustion gas supply to the heating trains under repair remains interrupted, so that via the flow path of the heating media (air and gas) of a heating train, only the combustion air flowing through the regenerator absorbs a certain amount of heat and releases it again to the newly installed heating trains to be heated. The combustion air is used as a heat transfer medium. In this way, simple and energy-efficient heating of the freshly bricked masonry is achieved.
Mit dem Fortschreiten der Mauerarbeiten wird die Luftumkehr- Vorrichtung schrittweise hoher gesetzt, so daß die neu gemauerten Teile des Heizzuges entsprechend erwärmt werden. Dabei ist die Luftumkehrvorrichtung so ausgebildet, daß jeweils 4-6 Lagen aufgemauert werden können.With the progress of the masonry work, the air reversing device is gradually set higher, so that the newly bricked parts of the heating train are heated accordingly. The air reversing device is designed so that 4-6 layers can be bricked up.
Die Regelung des Verbrennungsluftdurchflusses erfolgt mit den am Koksofen ohnehin vorhandenen Regelorganen. Zum genauen Regulieren des Verbrennungsluftdurchflusses und damit der Temperatur in den schon fertiggestellten Abschnitten der zu reparierenden Heizzuge erfolgt z. B. mittels eines Schie- bers in der Luftumkehrrichtung. Die Temperatur wird durchThe control of the combustion air flow is carried out with the control elements already present on the coke oven. To precisely regulate the combustion air flow and thus the temperature in the already completed sections of the heating trains to be repaired z. B. by means of a slide in the direction of air reversal. The temperature is through
Temperaturmeßstellen, die, insbesondere unterhalb, der Luftumkehrvorrichtung angeordnet sind, kontrolliert.Temperature measuring points, which are arranged, in particular below, the air reversing device are controlled.
Die Kosten für das Aufheizen der Heizzuge werden durch diese einfache Verfahrensweise verringert. D. h., eine Reparatur nach diesem Verfahren wird erheblich preiswerter.This simple procedure reduces the cost of heating the heating trains. That is, a repair using this method will be significantly cheaper.

In den Heizzugpaaren 1 und 2 sind jeweils eine Luftumkehrvorrichtung 3, mit Luftuberleitrohren 4 und 4', angeordnet. Die Luftuberleitrohre 4 und 4' sind an ihrem unteren Ende mit Abdeckplatten 17, 17', die den fertiggemauerten Teil der Heizzuge 1 und 2 von dem noch aufzumauernden Teil abtrennen, gasdicht verbunden. Die Luftuberleitrohre 4' sind jeweils mit einem Schieber 5 versehen, mit dem die Luftmenge zur Einstellung der gewünschten Temperatur von ca. 250° C unterhalb der Luftumkehrvorrichtung 3 geregelt werden kann. Die Temperatur unterhalb der Luftumkehrvorrichtung wird mit Thermoelementen 6 gemessen.Fig. 3B the same air reversing device in plan view (section along the line III B - III 3B of FIG. 3A). 1 shows a section through two pairs of heating cables 1 and 2 to be repaired. In the heating cable pairs 1 and 2, an air reversing device 3, with air transfer tubes 4 and 4 ', is arranged in each case. The Luftuberleitrohre 4 and 4 'are gas-tightly connected at their lower end with cover plates 17, 17', which separate the prefabricated part of the heating elements 1 and 2 from the part still to be bricked up. The air transfer tubes 4 'are each provided with a slide 5, with which the amount of air for setting the desired temperature of about 250 ° C below the air reversing device 3 can be controlled. The temperature below the air reversing device is measured with thermocouples 6.
Der Stromungsweg der Verbrennungsluft ist durch Pfeile dargestellt. Gemäß Pfeil 7 (Fig. 1 und 2) strömt die Verbrennungsluft in den Regeneratorsohlkanal 23, durchströmt den Regenerator 8 und tritt an der Brennerebene 9 in das zu reparierende Heizzugpaar 1 ein. Die Verbrennungsluft durch- strömt dann die Luftumkehrrohre 4 und 4' und strömt in dem abfallendem Heizzug 1 über die Brennerebene 10 in einen Nachbarregenerator 11 und tritt dort über den Regeneratorsohlkanal 23 gemäß Pfeil 12 zum Kamin hinaus.The flow path of the combustion air is shown by arrows. According to arrow 7 (FIGS. 1 and 2), the combustion air flows into the regenerator channel 23, flows through the regenerator 8 and enters the pair of heating cables 1 to be repaired at the burner level 9. The combustion air then flows through the air reversal pipes 4 and 4 'and flows in the descending heating train 1 via the burner level 10 into a neighboring regenerator 11 and exits there via the regenerator channel 23 according to arrow 12 to the chimney.
Die Stromungsgeschwindigkeit der Verbrennungsluft wird durch den Kaminzug bestimmt sowie durch die Einstellung der Regelamaturen des Koksofens, die in der Fig. 1 nicht darge¬ stellt sind. Eine weitere Regelung des Verbrennungsluftdurchflusses wird mit dem Schieber 5 der Luftumkehr- Vorrichtung 3 vorgenommen.The flow velocity of combustion air is determined by the chimney draft, as well as by adjusting the Rege Lama doors of the coke oven, the non Darge in FIG. 1 ¬ is shown. A further control of the combustion air flow is carried out with the slide 5 of the air reversing device 3.
Die Fig. 2 zeigt einen senkrechten Schnitt durch drei neu aufzumauernde Heizzuge 14, 15 und 16. Die Luftumkehrvorrichtung 3 besteht in diesem Fall aus mehr Teilen. In ein Zwi- schenteil 13 werden die Luftuberleitrohre 4, 4' und 4'' hin- eingesteckt. In diesem Fall sind die Luftuberleitrohre 4'' und 4' jeweils mit einem Schieber 5 versehen. Die übrigen Bezugszeichen haben die gleiche Bedeutung wie m der Fig. 1. Die Verbrennungsluft strömt durch den mittleren Heizzug 14 nach oben durch die Luftumkehrvorrichtung 3, verteilt sich m den abfallenden Heizzugen 15 und 16 und fließt wieder über den Regenerator 8 zu den entsprechenden Abgasventilen an dem Koksofen. Nach dem Umschalten des Regenerators strömt die Verbrennungsluft m den Heizzugen 15 und 16 gemäß den eingeklammerten Pfeilen nach oben, wird über den Heizzug 14 abgesaugt und fließt durch den Regenerator 8 zu dem entsprechenden Rauchgasventil des Koksofens.FIG. 2 shows a vertical section through three new heating elements 14, 15 and 16 to be walled up. In this case, the air reversing device 3 consists of more parts. The air transfer tubes 4, 4 ′ and 4 ″ are inserted into an intermediate part 13 plugged in. In this case, the air transfer pipes 4 ″ and 4 ′ are each provided with a slide 5. The remaining reference numerals have the same meaning as m in FIG. 1. The combustion air flows through the central heating train 14 upward through the air reversing device 3, is distributed in the falling heating trains 15 and 16 and flows again via the regenerator 8 to the corresponding exhaust gas valves the coke oven. After switching over the regenerator, the combustion air flows upward in the heating elements 15 and 16 according to the bracketed arrows, is sucked off via the heating element 14 and flows through the regenerator 8 to the corresponding flue gas valve of the coke oven.
Aus der Fig. 3 A/B geht die genaue Anordnung der Luftumkehr- Vorrichtung 3 m den zu reparierenden Heizzugen, die aus den Binderwanden 19 und den Lauferwanden 24 bestehen, hervor. Die Luftumkehrvorrichtung besteht aus den Luftuberleitrohren 4 und 4', die gasdicht mit den Abdeckplatten 17, 17' verbunden sind, die Luftuberleitrohre 4 und ' werden mit ihren waagerechten Enden ineinander gesteckt und mit Hilfe mindestens einer Verriegelung 18, die auf der Abdeckplatte 17, 17' aufgeordnet ist, jeweils m den Fugen des Heizzugmauerwerkes arretiert. So ist wahrend des weiteren Aufmauerns ein schnelles Umsetzen der Luftumkehrvorrichtung 3 möglich. Die Luftuberleitrohre 4 und 4' sind derart ausgebildet, daß jeweils 4 bis 6 Lagen der Bmderwande 19 und der Lauferwande 24 aufgemauert werden können.3 A / B shows the exact arrangement of the air reversing device 3 m from the heating trains to be repaired, which consist of the binder walls 19 and the runner walls 24. The air reversing device consists of the air guide tubes 4 and 4 ', which are connected gas-tight to the cover plates 17, 17', the air guide tubes 4 and 'are inserted into one another with their horizontal ends and by means of at least one lock 18, which is on the cover plate 17, 17 'is arranged, each m the joints of the heating brickwork locked. Thus, the air reversing device 3 can be quickly moved during the further bricking up. The Luftuberleitrohre 4 and 4 'are designed such that 4 to 6 layers of the Bmderwande 19 and the Lauferwande 24 can be bricked up.
Zum Warmeschutz der Maurer und zur besseren Isolierung der Luftumkehrvorrichtung 3 wird diese mit z. B. Isolierwolle 20 umwickelt. Die Abdeckplatten 17 sollten ebenfalls an ihrer Unterseite mit Isolierwolle 21 beklebt werden. Dadurch wird auch die Abdichtung zu den Binderwanden 19 und den Lauferwanden (24) verbessert. Die Durchstromung der Luftumkehrvor- πchtung 3 wird durch die Pfeile 22 dargestellt, die Rieh- tung ändert sich entsprechend der Beheizungsumstellung der Koksofenbatterie und dem Umstellzeitraum jeweils in ca. 20 Minuten. For thermal protection of the masons and for better insulation of the air reversing device 3, this is z. B. wrapped in insulating wool 20. The cover plates 17 should also be covered with insulating wool 21 on their underside. This also improves the seal to the girder walls 19 and the runner walls (24). The flow through the air reversal device 3 is represented by the arrows 22; The system changes according to the heating changeover of the coke oven battery and the changeover period in about 20 minutes.
