Abstract

1. Process for improving the quality, especially for increasing the content of volatile hydrocarbons, of the gas formed in the coking of mineral coal in horizontal-chamber coking furnaces, in which the gas is drawn off through the horizontally extending gas-collecting chamber remaining between furnace charge and coke furnace top and connected to the collecting main of the coke furnace battery, characterised in that the gas is drawn off at the same time also at the two ends of the coke furnace by way of vertical collecting chambers corresponding approximately to the volume of the gas-collecting chamber formed above the furnace charge, in such a way that the quantity of the gas which rises vertically upwards through the furnace charge and is drawn off through the horizontal gas-collecting passage is substantially reduced and the gas withdrawn at the ends of the furnace through the vertical collecting chambers is conducted away directly into the collecting main of the coke furnace battery.

Description

Die Erfindung betrifft ein Verfahren zur Verbesserung der Gasqualität des insbesondere bei der Verkokung von Steinkohle in Horizontalkammerverkokungsöfen frei werdenden bzw. entstehenden Gases, bei dem das Gas über den zwischen Ofenfüllung und Koksofendecke verbleibenden horizontal verlaufenden und an die Vorlage 'der Koksofenbatterie angeschlossenen Gassammelraum abgesaugt wird.The invention relates to a method for improving the gas quality of the gas which is released or generated, in particular, when coking coal in horizontal chamber coking ovens, in which the gas is sucked off via the gas collection space which runs horizontally between the oven filling and the coke oven ceiling and is connected to the template 'of the coke oven battery.

Bei den heute fast ausschließlich eingesetzten Koksöfen wird die Kokskohle von oben aus in die annähernd rechteckförmigen Koksöfen eingefüllt und dann von den Längsseiten her aufgeheizt und verkokt. Nach dem Einfüllen der Kokskohle wird die Ofenfüllung maschinell planiert, um zwischen Koksofendecke und Ofenfüllung einen gleichmäßig ausgebildeten und ausreichend großvolumigen Gassammelraum zu schaffen, über den das Gas dann über die gesamte Länge des Koksofens abgesaugt wird. Seitlich werden die Koksöfen durch Koksofentüren mit Türstopfen aus feuerfestem Material begrenzt, wobei über die Türstopfen einerseits ein Schutz für die Koksofentüren selbst und andererseits eine möglichst gleichförmige Verkokung der Ofenköpfe dadurch erreicht wird, daß die Ofenfüllung über den Türstopfen bis in den Bereich der ersten Heizzüge zurückgedrängt ist.iDurch diese Ausbildung des Türstopfens ist die Dichtungsfuge der Wärmeeinwirkung des ersten Heizzuges und des Kokskuchens weitgehend entzogen, wobei zwischen dem Türstopfen und der Ofenwandung ein schmaler von oben nach unten beidseitig des Türstopfens durchgehender Kanal verbleibt. Durch diesen schmalen Kanal kann eine ganz geringe Menge an Gas am Türkörper entlang nach oben entweichen. Aufgrund der Ausbildung dieses schmalen Kanals kommt es insbesondere zu Beginn des Verkokungsprozesses zu hohen Drücken, so daß das Gas nicht durch die Kanäle abgeführt, sondern vielmehr durch die Dichtleiste hindurch in die Atmosphäre dringt. Entsprechend schädliche Immissionen sind die Folge.In the coke ovens used almost exclusively today, the coking coal is filled from above into the approximately rectangular coke ovens and then heated and coked from the long sides. After the coking coal has been filled in, the furnace filling is leveled mechanically in order to create a uniformly designed and sufficiently large-volume gas collecting space between the coke oven ceiling and the furnace filling, through which the gas is then sucked off over the entire length of the coke oven. The coke ovens are opened on the sides through coke oven doors with door plugs made of refractory material limits, on the one hand protection for the coke oven doors themselves and on the other hand the most uniform coking of the furnace heads is achieved by pushing the furnace filling over the door plugs back into the area of the first heating flues The heat from the first heating flue and the coke cake are largely removed, with a narrow channel remaining from top to bottom on both sides of the door plug between the door plug and the furnace wall. A very small amount of gas can escape upwards along the door body through this narrow channel. Due to the formation of this narrow channel, high pressures occur in particular at the beginning of the coking process, so that the gas does not escape through the channels, but rather penetrates into the atmosphere through the sealing strip. This results in harmful emissions.

Es sind verschiedene Vorschläge bekanntgeworden, die Kanäle am Türkörper bzw. am Türstopfen zu erweitern. Diese Versuche zeigten auf der Druckseite kurzfristige Erfolge. Die Kanäle setzten sich jedoch aufgrund des dann erhöhten Temperaturgefälles um so schneller mit Teerkondensaten zu, was sowohl'bezüglich der Gasführung wie auch der Reinigung der Koksofentüren erhebliche Probleme mit sich brachte. Der Ersatz der Steinstopfen durch metallene Stopfen (US-PS 4 118 282) führte ebensowenig zum Erfolg, weil hier zu den Kondensatproblemen zusätzlich Materialschwierigkeiten und pyhsikalische Probleme mit der größeren Ausdehnung des Materials hinzukamen. Aufgrund des immer noch kleinen Querschnittes dieser Kanäle kann allenfalls das im unmittelbaren Türbereich freigesetzte Gas durch diese Kanäle entweichen. Aufgrund des bei diesen bekannten Koksöfen und bekannten Verfahren ungenügenden Verkokungsprozesses im Bereich der Koksofentür , wird das Gas im übrigen daran gehindert, überhaupt in den Bereich der Kanäle vorzudringen. Nachteilig ist beim bekannten Verkokungsprozeß, daß die entstehenden Gase annähernd zu 100 % durch die Ofenfüllung hindurch in den oberen horizontalen Gassammelraum aufsteigen, um von hier aus in die Vorlage abgesaugt und der weiteren Gasverwertung zugeführt zu werden. Dabei werden die Gase insbesondere beim Fortgang des Verkokungsprozesses gecrackt und ihr Gehalt an flüssigen Kohlenwasserstoffen damit reduziert. Nachteilig ist darüberhinaus, daß die abgesaugten Gase im Bereich der Vorlage hohe Temperaturen aufweisen und für die weitere Gasverarbeitung abgekühlt werden müssen.Various proposals have become known for expanding the channels on the door body or on the door plug. These attempts showed short-term success on the print side. However, due to the then increasing temperature gradient, the channels clogged with tar condensates all the more quickly, which brought considerable problems both with regard to the gas flow and the cleaning of the coke oven doors. The replacement of the stone plugs by metal plugs (US Pat. No. 4,118,282) was also unsuccessful because, in addition to the condensate problems, there were additional material difficulties and physical problems with the larger expansion of the material. Due to the still small cross-section of these channels, the gas released in the immediate door area can escape through these channels. Due to the insufficient coking process in the area of the coke oven door in these known coke ovens and known methods, the gas in the others prevented from entering the canal area at all. A disadvantage of the known coking process is that the resulting gases rise approximately 100 % through the furnace filling into the upper horizontal gas collecting space, in order to be sucked off into the receiver from here and used for further gas utilization. The gases are cracked, particularly as the coking process progresses, thereby reducing their liquid hydrocarbon content. A further disadvantage is that the extracted gases have high temperatures in the area of the receiver and have to be cooled down for further gas processing.

Der Erfindung liegt die Aufgabe zugrunde, die Gasqualität zu verbessern und dabei gleichzeitig die Ausgarung der Kopfpartien der Ofenfüllung zu verbessern und zu vergleichmäßigen.The invention has for its object to improve the gas quality and at the same time to improve and even out the cooking of the top parts of the furnace filling.

Die Aufgabe wird gemäß der Erfindung dadurch gelöst, daß das Gas gleichzeitig auch an den Stirnseiten des Koksofens gezielt abgesaugt wird.The object is achieved according to the invention in that the gas is also sucked off selectively at the end faces of the coke oven.

Durch das gezielte Absaugen des Gases im Bereich der Stirnseiten des Koksofens bzw. der Ofenfüllung wird die Menge des Gases, das durch die Ofenfüllung senkrecht nach oben steigen und durch den horizontalen Gassammelkanal abgesaugt werden muß, wesentlich verringert. Vielmehr kann das Gas nun bis zu einem gewissen Bereich in die Ofenfüllung hinein auf kurzem Wege abgesaugt und dann unmittelbar in die Vorlage abgeleitet werden. Dadurch steigt der Anteil an flüchtigen Kohlenwasserstoffen erheblich.By selectively sucking off the gas in the area of the end faces of the coke oven or the furnace filling, the amount of gas that has to rise vertically upwards through the furnace filling and must be extracted through the horizontal gas collection channel is significantly reduced. Rather, the gas can now be sucked up to a certain area into the furnace filling in a short way and then discharged directly into the receiver. As a result, the proportion of volatile hydrocarbons increases considerably.

Um eine möglichst große Menge des Gases daran zu hindern, durch den heißen Kokskuchen nach oben zu wandern und dabei gecrackt zu werden und um eine gezielte und gleichmäßige Absaugung zu gewährleisten, ist erfindungsgemäß vorgesehen, daß das Gas an den Stirnseiten des Koksofens durch einen großvolumigen, im Querschnitt in etwa dem oberhalb der Ofenfüllung ausgebildeten Gasabführungsraum entsprechenden, vertikalen Gassammelraum abgesaugt und abgeführt wird. Das Gas wird dabei über den großvolumigen vertikalen Gassammelraum bei einem Temperaturniveau abgeführt, das eine Kondensatbildung weitgehend vermeidet. Damit wird erreicht, daß sich die Tür beinahe von selbst reinigt, bis auf geringe Rückstände im horizontalen Bereich an der Unterseite der Tür. Der Wartungsaufwand beim Betrieb von Verkokungsöfen wird dadurch wesentlich reduziert. Bei entsprechender Ausbildung des großvolumigen Gassammelraumes kann die Gasqualität wie erwähnt entscheidend verbessert werden, wobei Versuche gezeigt haben, daß die entweichenden Gase im Bereich von etwa 45° unterhalb der Oberkante der Ofenfüllung von der Tür zum Inneren der Ofenkammer hin nicht mehr durch den heißen Kokskuchen in den horizontalen Gassammelraum entweichen, sondern vielmehr direkt in den vertikalen großvolumigen Gassammelraum mit dem entsprechend höheren Anteil an flüssigen Kohlenwasserstoffen.In order to prevent as much of the gas as possible from wandering up through the hot coke cake and being cracked in the process, and to ensure that it is targeted and even To ensure extraction, it is provided according to the invention that the gas is sucked off and discharged at the end faces of the coke oven through a large-volume, vertical gas collection space corresponding in cross-section approximately to the gas discharge space formed above the furnace filling. The gas is discharged through the large-volume vertical gas collection chamber at a temperature level that largely prevents condensation. This ensures that the door almost cleans itself, except for small residues in the horizontal area on the underside of the door. This significantly reduces the maintenance effort when operating coking ovens. With appropriate design of the large-volume gas collecting space, the gas quality can be decisively improved as mentioned, whereby tests have shown that the escaping gases in the region of approximately 45 ° below the upper edge of the furnace filling from the door to the interior of the furnace chamber no longer through the hot coke cake in the horizontal gas collecting space escape, but rather directly into the vertical, large volume gas collecting space with the correspondingly higher proportion of liquid hydrocarbons.

Das Entweichen des freigesetzten Gases aus dem Kokskuchen bzw. der Ofenfüllung in Richtung auf die vertikalen großvolumigen. Gassammelräume wird erfindungsgemäß weiter dadurch verbessert, daß die von den Gasen mitgeführte Wärme sowie die Wärme der ersten Heizzüge und die vom Koks ausgehende Reflektionswärme zur Beheizung der Verkokungsplatte verwendet wird. Auf diese Weise wird eine gleichmäßige Entgasung der Ofenfüllung im Bereich der Koksofentür sichergestellt, was sowohl die Gasabführung in diesem Bereich erleichtert, als auch die Menge des Gases mit höherem Anteil an flüssigen Kohlenwasserstoffen erhöht. Darüberhinaus tritt der positive Effekt ein, daß das der Vorlage zugeführte Gas eine um etwa 5o niedrigere Temperatur aufweist, als bei Vorhandensein nur des horizontalen Gassammelraumes.The escape of the released gas from the coke cake or the furnace filling in the direction of the vertical large volume. Gas collecting spaces is further improved according to the invention in that the heat carried by the gases and the heat of the first heating trains and the heat of reflection emanating from the coke is used to heat the coking plate. In this way, a uniform degassing of the furnace filling in the area of the coke oven door is ensured, which both facilitates gas removal in this area and also increases the amount of gas with a higher proportion of liquid hydrocarbons. In addition, there is the positive effect that the gas supplied to the receiver is at a temperature which is about 50 ° lower points than when only the horizontal gas collecting space is present.

Die Erfindung zeichnet sich insbesondere dadurch aus, daß durch eine Erhöhung der flüssigen Kohlenwasserstoffe im Gas der Wert des gewonnenen Gases erhöht wird, wobei zugleich durch die gleichmäßige Ausgarung der Kopfpartien auch eine Verbesserung und Vergleichmäßigung der Gasqualität sichergestellt wird.The invention is characterized in particular by the fact that an increase in the liquid hydrocarbons in the gas increases the value of the gas obtained, and at the same time an improvement and homogenization of the gas quality is ensured by the uniform cooking of the head parts.

Weitere Einzelheiten und Vorteile des Erfindungsgegenstandes ergeben sich aus der nachfolgenden Beschreibung der zugehörigen Zeichnung, die zur Verdeutlichung des Verfahrens nachfolgend erläutert wird. Dabei handelt es sich um eine perspektivische Teilansicht einer Koksofentür mit einem auf der Innenseite ausgebildeten großvolumigem Gassammelraum.Die Figur zeigt die wesentlichen Teile einer Koksofentür, mit der in den Koksofen hineinzeigenden Seite nach oben gewandt. Der die Armaturen tragenden Türkörper ist mit 1 bezeichnet. Seitlich daran sind Dichtleisten angeordnet, die beim Einschwenken der Koksofentür am Türrahmen anliegen und dadurch zu der gewünschten Abdichtung des Koksofens gegenüber der Atmosphäre führen.Further details and advantages of the subject matter of the invention result from the following description of the accompanying drawing, which is explained below to clarify the method. This is a partial perspective view of a coke oven door with a large-volume gas collecting space formed on the inside. The figure shows the essential parts of a coke oven door with the side facing the coke oven facing upwards. The door body carrying the fittings is designated by 1. Sealing strips are arranged on the side, which rest against the door frame when the coke oven door is swiveled in, thereby leading to the desired sealing of the coke oven from the atmosphere.

Auf der Innenseite des Türkörpers 1 ist der besonders ausgebildete und mit 4 bezeichnete Türstopfen angeordnet, der entsprechend weit in die Ofenkammer hineinragt und unter Belassung seitliche, schmaler Durchlässe für das Gas zwischen der Türfüllung und dem Türkörper 1 den großvolumigen Gassammelraum 7 ergibt. Durch den Gassammelraum 7 kann das Gas vom Boden der Ofenkammer zu dem im Bereich der Decke angeordneten Steigrohr und in die Vorlage aufsteigen. Zwischen dem Türstopfen bzw. der Platte 16 und dem Türkörper 1 befindet sich eine Wärmeisolierung, die den Türkörper schützt und eine Abkühlung des durch den Gassammelraum 7 streichenden Gases verhindert.On the inside of the door body 1, the specially designed and designated 4 door plug is arranged, which protrudes correspondingly far into the furnace chamber and leaves lateral, narrow passages for the gas between the door panel and the door body 1, the large-volume gas collecting space 7. Through the gas collecting space 7, the gas can rise from the bottom of the furnace chamber to the riser pipe arranged in the area of the ceiling and into the receiver. Between the door plug or the plate 16 and the door body 1 there is thermal insulation which protects the door body and a cooling of the by Prevents gas collecting space 7 streaking gas.

Der mit 4 bezeichnete Türstopfen ist hier durch die T-förmig ausgebildeten Distanzstücke 18, 19 und die darauf liegenden Abschnitte 29, 30, 31 der Platte 16 gebildet. Die einzelnen Abschnitte 29,3o, 31 sind mit einem gewissen Abstand zueinander angeordnet und liegen auf dem größeren Flansch der Distanzstücke 18, 19 auf. Auf die einzelnen Abschnitte 29, 30, 31 sind Verstärkungseisen 25, 26 aufgesetzt, so daß die Platte 16 selbst aus dünnem Blech gefertigt werden kann.The labeled door plug 4 is here formed by the T-shaped spacers 18, 19 and the lying thereon sections 29, 3 0, 31 of the plate sixteenth The individual sections 29, 31, 31 are arranged at a certain distance from one another and lie on the larger flange of the spacers 18, 19. Reinforcing irons 25, 26 are placed on the individual sections 29, 30 , 31 so that the plate 16 itself can be made from thin sheet metal.

Die Darstellung verdeutlicht, daß die Gase bei einem derart ausgebildeten vertikalen Gassammelraum sehr gut in diesen an der Platte 16 vorbei eindringen und dann durch diesen abgesaugt werden können. Die einzelnen Distanzstücke 18, 19 stellen keine Behinderung für das abgesaugte bzw. abgeführte Gas dar, zumal sie im Abstand zueinander angeordnet sind. Auch auf der Druckseite, wo oben an der Tür ein Kasten zur Durchführung der Planierstange vorgesehen ist, wird der Planierkasten so ausgebildet, daß das Gas seitlich daran vorbeigeführt werden kann.The illustration shows that the gases in a vertical gas collecting space designed in this way penetrate very well past the plate 16 and can then be sucked off through it. The individual spacers 18, 19 do not constitute a hindrance to the extracted or discharged gas, especially since they are arranged at a distance from one another. Also on the pressure side, where a box for carrying out the leveling rod is provided at the top of the door, the leveling box is designed such that the gas can be guided past it laterally.

Da die*hitzebeständige Platte 16 vorzugsweise aus einem Metall bzw. aus Stahl mit einer hohen Wärmeleitfähigkeit hergestellt ist, erfolgt eine Wärmezufuhr vom Gas an die Ofenfüllung, so daß diese Partien nicht nur seitlich von den Heizwänden her,sondern zugleich auch über diese Platte 16 aufgewärmt und erhitzt werden. Die dadurch erzielte einwandfreie Abgarung der Kopfpartien führt zu einer Verbesserung der Gasabführung in diesem Bereich in den Gassammelraum und erbringt gleichzeitig beim Koksdrücken wesentlich geringere Emissionen, da vollwertiger Koks hier ansteht.Since the * heat-resistant plate 16 is preferably made of a metal or steel with a high thermal conductivity, heat is supplied from the gas to the furnace filling, so that these parts are not only heated laterally from the heating walls, but also via this plate 16 and be heated. The resultant flawless removal of the head parts leads to an improvement in the gas discharge in this area into the gas collection space and, at the same time, produces significantly lower emissions when coke is pressed, since full coke is present here.
