Abstract

In a coke oven battery, heated with lean gas, an additional sealing is fitted to the wall of the regenerator dividing wall to reduce the CO content in the exhaust gas. Also claimed is a coke oven battery with a fine steel plate (2) in front of the regenerator dividing wall (1), pref. with an intermediate layer behind it of ceramic fibres. The facing fine steel plates (2) are held apart and supported by tensioner rods (4).

Description

Die Erfindung betrifft ein Verfahren und eine Vorrichtung zur Reduzierung des CO-Gehaltes im Abgas von mit Schwachgas beheizten Koksofenbatterien.The invention relates to a method and a device for reducing the CO content in the exhaust gas of lean gas coke oven batteries.

Für die Beheizung von Koksofenbatterien wird vielfach sogenanntes Schwachgas verwendet. Hierbei handelt es sich in der Regel um leicht aufcarboriertes Gichtgas, das einen CO-Gehalt von ca. 20 Vol.-% aufweist. Bei einer sauberen Verbrennungseinstellung werden CO-Gehalte im Bereich zwischen 50 und 200 ppm erwartet. In der Praxis hat sich allerdings gezeigt, daß in vielen Fällen Werte von 500 bis 2000 ppm CO im Abgas auftreten, obwohl eine gute Einstellung der Verbrennungsverhältnisse erfolgte.So-called lean gas is often used to heat coke oven batteries. This is usually a slightly carburized blast furnace gas with a CO content of approx. 20 vol.%. With a clean combustion setting, CO contents in the range between 50 and 200 ppm are expected. In practice, however, it has been shown that values of 500 to 2000 ppm CO occur in the exhaust gas in many cases, although the combustion conditions have been set well.

Infolge der immer strenger werdenden Umweltschutzauflagen sowie der immer genaueren Analyseverfahren wird die Forderung erhoben, den CO-Gehalt im Abgas der Koksofenbatterien möglichst niedrig zu halten.As a result of increasingly stringent environmental protection requirements and increasingly precise analysis methods, the demand is being made to keep the CO content in the exhaust gas from the coke oven batteries as low as possible.

Der Erfindung liegt deshalb die Aufgabe zugrunde, eine geeignete Lösung für dieses Problem zu finden.The object of the invention is therefore to find a suitable solution to this problem.

Zur Lösung dieses Problems wird bei einem Verfahren der eingangs genannten Art erfindungsgemäß vorgeschlagen, daß das Mauerwerk der Regeneratortrennwände der Koksofenbatterie mit einer zusätzlichen, horizontal wirksamen Abdichtung versehen wird.To solve this problem, it is proposed according to the invention in a method of the type mentioned at the outset that the masonry of the regenerator partition walls of the coke oven battery is provided with an additional, horizontally effective seal.

Weiterbildungen des Verfahrens bzw. der Vorrichtung erfolgen gemäß den Merkmalen der Ansprüche 2 bis 8.Further developments of the method and the device take place according to the features of claims 2 to 8.

Der Erfindung liegt dabei die Erkenntnis zugrunde, daß das stark ausgeprägte temperaturabhängige Dehnen und Schrumpfen der für den Aufbau der Regeneratorwände verwendeten Silika- und Schamottesteine zum Auftreten von Haarrissen in den Mörtelfugen des Mauerwerks der Regeneratortrennwände führen kann und durch diese Haarrisse das zwecks Vorwärmung durch den Regenerator strömende Schwachgas zum Teil in benachbarte Regeneratorzellen, die von den Verbrennungsabgasen durchströmt werden, gelangen kann. Diese Gasübertritte führen dann zu einer entsprechenden Erhöhung des CO-Gehaltes im Abgas.The invention is based on the knowledge that the pronounced temperature-dependent stretching and shrinking of the silica and firebricks used for the construction of the regenerator walls can lead to hairline cracks in the mortar joints of the masonry of the regenerator partition walls and through these hairline cracks for preheating by the regenerator flowing lean gas can partly reach neighboring regenerator cells through which the combustion exhaust gases flow. These gas transfers then lead to a corresponding increase in the CO content in the exhaust gas.

Durch die erfindungsgemäße Abdichtung der Regeneratortrennwände werden unerwünschte Gasübertritte von Schwachgas in den Abgaskanal unterbunden. Die zusätzliche Abdichtung kann dabei entweder an bzw. auf den medienbeberührten Flächen der Regeneratortrennwänden durch Platten aus einem hitzebeständigen Material erfolgen, oder es wird eine zusätzliche Abdichtung innerhalb des Mauerwerks der Regeneratortrennwände vorgenommen.The inventive sealing of the regenerator partition walls prevents unwanted gas transfers from lean gas into the exhaust gas duct. The additional sealing can be carried out either on or on the media-contacting surfaces of the regenerator partition walls by means of plates made of a heat-resistant material, or an additional sealing is carried out within the masonry of the regenerator partition walls.

Zur Abdichtung der Regeneratortrennwände können die vorstehend beschriebenen Maßnahmen auch in Kombination miteinander zur Anwendung gelangen.The measures described above can also be used in combination with one another to seal the regenerator partition walls.

Ausführungsbeispiele der Erfindung werden nachfolgend anhand der Zeichnung erläutert. Hierin zeigen:

Bei der Ausführungsform gemäß Fig. 1 und zur Abdichtung sind vor den gasberührten Flächen der Regeneratortrennwände 1 Edelstahlbleche 2 angeordnet. Um den Abdichtungseffekt noch weiter zu verbessern, ist zwischen dem Edelstahlblech 2 und der Regeneratortrennwand 1 noch eine Zwischenschicht 3 aus einem Dichtungsmaterial angeordnet. Hierfür können beispielsweise kompressible temperaturbeständige Matten aus keramischer Faser oder aber auch feuerfeste Stampfmassen verwendet werden. Im vorliegenden Ausführungsbeispiel werden jeweils einander gegenüberliegende Edelstahlbleche 2 mit der darunter liegenden Zwischenschicht 3 durch die stabförmigen Spannvorichtungen 4 in Position gehalten, die im gespreizten Zustand die Edelstahlbleche 2 an die Regeneratortrennwände 1 pressen. Grundsätzlich ist es aber auch möglich sowohl die Edelstahlbleche 2 als auch die Zwischenschicht 3 durch Verklebung mittels eines hierfür geeigneten temperaturbeständigen Klebstoffes an der Regeneratortrennwand 1 zu befestigen. Anstelle der Edelstahlbleche 2 kann natürlich auch ein anderes hierfür geeignetes plattenförmiges Material verwendet werden. Bei der in Fig. 1 dargestellten Ausführungsform handelt es sich um einen sogenannten Unterbrenner-Verbundkoksofen. Bei dieser Ausführungsform ist jede zweite Regeneratortrennwand 1 mit einem senkrecht nach oben verlaufenden Starkgaskanal 5 versehen. Jede Regeneratortrennwand trennt zwei benachbarte Regeneratorkammern 6.Embodiments of the invention are explained below with reference to the drawing. Show here:

Fig. 9.
a vertical section along the line IX - IX of Fig. 8
In the embodiment according to FIG. 1 and for sealing, 1 stainless steel sheets 2 are arranged in front of the gas-contacting surfaces of the regenerator partition walls. In order to improve the sealing effect even further, an intermediate layer 3 made of a sealing material is arranged between the stainless steel sheet 2 and the regenerator partition 1. For this purpose, compressible, temperature-resistant mats made of ceramic fiber or also refractory ramming compounds can be used. In the present exemplary embodiment, opposite one another stainless steel sheets 2 with the underlying intermediate layer 3 are held in position by the rod-shaped tensioning devices 4, which press the stainless steel sheets 2 against the regenerator partition walls 1 in the spread state. In principle, however, it is also possible to fasten both the stainless steel sheets 2 and the intermediate layer 3 to the regenerator partition wall 1 by gluing with a suitable temperature-resistant adhesive. Instead of the stainless steel sheets 2, another plate-shaped material suitable for this can of course also be used. The embodiment shown in FIG. 1 is a so-called underburner composite coke oven. In this embodiment, every second regenerator partition 1 is provided with a high-pressure gas duct 5 running vertically upwards. Each regenerator partition divides two adjacent regenerator chambers 6.

Die Figuren 2 - 5 zeigen ausschnittweise den Aufbau von Regeneratortrennwänden 1, bei denen die Abdichtung mittels gasdichter Folien 7 erfolgt, die in den Vertikalfugen hinter den Rechtecksteinen 8 angeordnet sind. Als gasdichte Folien können dabei Folien aus z.B. Metall verwendet werden. Die Figuren 2 und 3 betreffen dabei die Regeneratorwand eines Unterbrenner-Verbundkoksofens, wobei Figur 2 einen Horizontalschnitt zeigt und Figur 3 einen Vertikalschnitt entlang der strichpunktierten Linie in Fig. 2. Die entsprechenden Darstellungen in Figur 4 und Figur 5 zeigen den Aufbau der Regeneratorwand 1 bei einem kopfbeheizten Verbundkoksofen. Hier entfallen die vertikalen Starkgaskanäle 5. Stattdessen sind in diesem Falle horizontale Kanäle vorgesehen, die in Figur 4 und Figur 5 jedoch nicht zu erkennen sind.FIGS. 2-5 show sections of the structure of regenerator partition walls 1, in which the sealing takes place by means of gas-tight films 7, which are arranged in the vertical joints behind the rectangular blocks 8. Films made of metal, for example, can be used as gas-tight films. FIGS. 2 and 3 relate to the regenerator wall of an underburner composite coke oven, wherein FIG. 2 shows a horizontal section and FIG. 3 shows a vertical section along the dash-dotted line in FIG. 2. The corresponding representations in FIG. 4 and FIG. 5 show the structure of the Regenerator wall 1 in a head-heated composite coke oven. The vertical high-pressure gas channels 5 are omitted here. Instead, horizontal channels are provided in this case, but these cannot be seen in FIGS. 4 and 5.

Die Figuren 6 - 9 zeigen ausschnittsweise den Aufbau von Regeneratortrennwänden 1, bei denen in den zum Wandaufbau verwendeten Formsteinen neben Nut und Feder in den Stoßfugen zusätzliche Nuten vorgesehen sind, so daß aneinander stoßende Formsteine an den Vertikalflächen gemeinsam kreisrunde Kanäle 9 bilden. In diese Kanäle 9 kann beim Aufmauern der Regeneratortrennwände 1 eine Dichtungsmasse eingefüllt bzw. eingepreßt werden. Auch durch diese Maßnahme kann verhindert werden, daß durch eventuell offene gasseitige Stoßfugen Gas eindringt bzw. austritt. Als Dichtungsmaterial können feuerfesten Massen verwendet werden.FIGS. 6-9 show sections of the structure of regenerator partition walls 1, in which, in addition to tongue and groove, additional grooves are provided in the shaped stones used for the wall structure, so that abutting shaped stones jointly form circular channels 9 on the vertical surfaces. A sealing compound can be poured or pressed into these channels 9 when the regenerator partition walls 1 are bricked up. This measure can also be used to prevent gas from entering or escaping through any open gas-side butt joints. Refractory materials can be used as sealing material.

Die Figuren 6 und 7 betreffen dabei wiederum die Regeneratortrennwand 1 eines Unterbrenner-Verbundkoksofens, wobei Figur 6 einen Horizontalenschnitt zeigt und Figur 7 einen Vertikalschnitt entlang der strichpunktierten Linie in Figur 6. Die entsprechenden Darstellungen in Figur 8 und Figur 9 zeigen den Aufbau der Regeneratortrennwand 1 bei einem kopfbeheizten Verbundkoksofen. Bezüglich der Unterschiede zwischen den beiden Ofentypen wird auf die Ausführungen weiter oben zur Figur 2 bis Figur 5 verwiesen.FIGS. 6 and 7 in turn relate to the regenerator partition 1 of an underburner composite coke oven, wherein FIG. 6 shows a horizontal section and FIG. 7 shows a vertical section along the dash-dotted line in FIG. 6. The corresponding representations in FIG. 8 and FIG. 9 show the structure of the regenerator partition 1 in a head-heated composite coke oven. With regard to the differences between the two types of furnace, reference is made to the explanations above for FIGS. 2 to 5.

Zur Abdichtung der Regeneratortrennwände können selbstverständlich vorstehend beschriebenen Maßnahmen gegebenenfalls auch in Kombination untereinander zur Anwendung gelangen.The measures described above can of course also be used in combination with one another, of course, for sealing the regenerator partition walls.
