Description

Beheizungsräume in Koksöfen und Verfahren zur BeheizungBoiler rooms in coke ovens and methods of heating
Beschreibungdescription
In Koksöfen findet die Verkokung von Kohle unter Luftabschluß durch indirekte Beheizung statt. Dazu sind in den Koksofenwänden Beheizungsräume, Heizzüge vorgesehen. Den Beheizungsräumen werden die Verbrennungsmedien Gas und Luft zugeführt, dort gemischt und verbrannt. Die Zuführung wird zur Verminderung der in en entstehenden Rauchgasen enthaltenen Schadstoffen NO bevorzugt so angeordnet, daß die Verbrennungsluft in unterschiedlicher Höhe in den Verbrennungsraum eingeführt wird, um eine zunächst unterstöchio etrische Verbrennung mit möglichst niedrigen Temperaturen an der Flammenspitze zu erzielen.In coke ovens, coking of coal takes place with the exclusion of air through indirect heating. For this purpose, heating rooms and heating trains are provided in the coke oven walls. The combustion media are supplied with gas and air, where they are mixed and burned. The supply is preferably arranged to reduce the pollutants NO contained in the resulting flue gases so that the combustion air is introduced at different heights into the combustion chamber in order to achieve an initially substoichiometric combustion with the lowest possible temperatures at the tip of the flame.
Stoffe wie N0/N02 beschleunigen dabei die Flammreaktion. Um diesen Effekt zu kompensieren beziehungsweise die Flammenreaktion zu verlangsamen, kann Rauchgas zugeführt werden. Das Rauchgas kann der Verbrennungsluft zugemischt werden.Substances such as N0 / N0 2 accelerate the flame reaction. To compensate for this effect or to slow down the flame reaction, flue gas can be added. The flue gas can be added to the combustion air.
Allen bekannten Beheizungsräumen in Koksöfen sind jedoch unkontrollierte StrömungsVerhältnisse gemeinsam. Zum Teil bestehen ausgeprägte Rezirkulationsströmungen.However, uncontrolled flow conditions are common to all known heating rooms in coke ovens. In some cases there are pronounced recirculation currents.
Der Erfindung liegt die Aufgabe zugrunde, die Heizungs¬ und Strömungsverhältnisse in Beheizungsräumen von Koksöfen zu verbessern. Nach der Erfindung wird das durch Einbauten erreicht. Die Einbauten sind aus feuerfesten Baustoffen hergestellt, die in der Atmosphäre des Beheizungsraumes beständig sind und Temperaturen bis 1800° C standhalten. Nach der Erfindung werden die Einbauten durch Wabengitter und/oder Kugelschüttungen gebildet.The object of the invention is to improve the heating and flow conditions in the heating rooms of coke ovens. According to the invention, this is achieved by internals. The internals are made of fireproof building materials, which in the Atmosphere of the boiler room are stable and can withstand temperatures up to 1800 ° C. According to the invention, the internals are formed by honeycomb grids and / or ball beds.
Die Wabengitter bewirken eineThe honeycomb grids cause one
Strömungsvergleichmäßigung und können gegebenenfalls sogar eine getrennte Führung von Gas und Luft über eine festzulegende Entfernung verursachen, die im einzelnen von der Ofenhöhe und den geometrischen Abmessungen des Beheizungsraumes abhängt.Flow equalization and may even cause a separate routing of gas and air over a distance to be determined, which depends in detail on the furnace height and the geometric dimensions of the heating room.
Vorzugsweise ist der Beheizungsräum beziehungsweise die Beheizungsvorrichtung in unterschiedliche Zonen eingeteilt, in die Gas und Verbrennungsluft getrennt, auch in unterschiedlicher Höhe eingeführt werden. Dem Gas wird in einer ersten Stufe eine zur deutlichen unterstöchiometrischen Verbrennung benötigte Luftmenge zugeführt, danach in einer weiteren Stufe das noch nicht verbrannte Gas-Rauchgemisch, mit erneut von außen zugeführter Luft verbrannt. Auf diese Weise entstehen einzelne Verbrennungsreaktioneh, die gesondert mit Luft beaufschlagt werden. Im Ergebnis kann auf diese Weise auch über große Höhen eine annähernd gleichmäßige Verbrennung mit niedriger Flammenspitzentemperatur durchgeführt werden.The heating space or the heating device is preferably divided into different zones, into which gas and combustion air are separated, and also introduced at different heights. In a first stage, the gas is supplied with the amount of air required for significant sub-stoichiometric combustion, and in a further stage the gas-smoke mixture that has not yet been burned is burned with air supplied from outside again. In this way, individual combustion reactions occur, which are acted upon separately by air. As a result, an almost uniform combustion with a low flame tip temperature can also be carried out over great heights.
Durch die unterschiedliche Höhe des Wabengitters über den Querschnitt, die Höhe des Beheizungsraumes und getrennte Führungen der Verbrennungsmedien bis zum Gitteraustritt kann die Verbrennungsart abhängig von der in der jeweiligen Höhe benötigten Wärme selektiv eingestellt werden. Damit wird ein ein- oder zweiseitiger, pyramidenförmiger, über die Höhe abgestufter Flammenfortschritt möglich. Bei solchermaßen gestuftem Flammenfortschritt ist es nicht mehr notwendig, die Verbrennungsluft in unterschiedlichen Höhen zuzuführen.Due to the different height of the honeycomb grille over the cross-section, the height of the heating room and separate guides of the combustion media up to the grille outlet, the type of combustion can be set selectively depending on the heat required at the respective height. This turns one on or Double-sided, pyramid-shaped flame progress possible over the height. With such graded flame progress, it is no longer necessary to supply the combustion air at different heights.
Die Oberflächen der Waben können zusätzlich mit Katalysatormaterial beaufschlagt sein, das die entstehenden Schadstoffe, z. B. NO , am Ort derThe surfaces of the honeycombs can also be acted upon by catalyst material that the resulting pollutants, for. B. NO, at the location of

Über die Stegstärke kann ein zusätzlicher Einfluß auf die Wärmespeicherkapazität genommen werden, die bei momentan erhöhter Wärmeabfuhr den Temperaturabfall ausgleichen kann. Außerdem kann auf die Verbrennung durch Querschnittsänderung Einfluß genommen werden.The web thickness can have an additional influence on the heat storage capacity, which can compensate for the drop in temperature with currently increased heat dissipation. In addition, combustion can be influenced by changing the cross-section.
Bei erfindungsgemäßer Verwendung von Kugeln als Einbauten besteht die Möglichkeit der Füllung des Beheizungsraumes mit gleich großen keramischen Kugeln, so daß ein Freiraum von ca. 25 % (hexagonale, dichteste Kugelpackung) verbleibt. In diesem Fall wird neben der ausgeprägten Führung mit intensiver Vermischung der Verbrennungsmedien die Wärmespeicherkapazität des Beheizungsraumes wesentlich erhöht, so daß auch eine verfahrenstechnisch bedingte momentan erhöhte Wärmeabfuhr nicht zu Temperatursenkungen im Heizzug führt.When balls are used as internals according to the invention, there is the possibility of filling the heating space with ceramic balls of the same size, so that a free space of approximately 25% (hexagonal, densest ball packing) remains. In this case, in addition to the pronounced guidance with intensive mixing of the combustion media, the heat storage capacity of the heating room is significantly increased, so that even a heat dissipation which is currently caused by the process technology does not lead to temperature drops in the heating train.
