Abstract

1. Coke oven battery with half-divided regenerators for firing by rich gas and/or by lean gas, characterised in that the lower ovens have unequal widths in an alternating sequence, two adjacent lower ovens together having the same width as two upper ovens.

Description

Die Erfindung bezieht sich auf eine Verkokungs-Verbundofenbatterie mit halbgeteilten Regeneratoren für die Beheizung mit Stark- und/ oder Schwachgas.The invention relates to a coking composite oven battery with semi-divided regenerators for heating with high and / or low gas.

Bei der heutigen Energiesituation gewinnt das Schwachgas für die Beheizung von Verkokungsöfen auch bei sehr niedrigem Heizwert, beispielsweise von 3000 kJ/Nm3 an Bedeutung. Der Wunsch geht zunehmend dahin, die bisher übliche Zumischung von Starkgas bis auf einen Heizwert, bei dem die Gas- und Luftmengen, die durch den Ofen strömen, gleich sind, ganz oder teilweise zu sparen. Es sollen also in Zukunft auch solche Gichtgase verwendet werden, bei denen das Mengenverhältnis von Gas zu Luft wesentlich von 1 : 1 verschieden ist. Das bedeutet bei den Verkokungsöfen eine unterschiedliche Beaufschlagung benachbarter Regeneratoren für die Aufheizung von Gas und Luft.In today's energy situation, the lean gas for heating coking ovens is gaining importance even with a very low calorific value, for example of 3000 kJ / Nm 3 . There is an increasing desire to save all or part of the hitherto usual admixture of high-power gas to a calorific value at which the gas and air quantities flowing through the furnace are the same. In the future, such top gases should also be used in which the ratio of gas to air differs significantly from 1: 1. With coking ovens, this means that different regenerators for heating gas and air are acted on differently.

Aufgabe der Erfindung ist es, auch solche Gase in Verkokungsofenbatterien für die Unterfeuerung zu nutzen, ohne daß dabei die Wirkungsgrade des Wärmeaustausches sinken und durch die Unterschiedlichkeit der strömenden Mengen nennenswerte Druckdifferenzen in den benachbarten Kammern auftreten oder Taupunktunterschreitungen in den Regeneratoren vorkommen können.The object of the invention is also to use such gases in coking furnace batteries for underfiring, without the efficiency of the heat exchange falling and due to the difference in the flowing quantities appreciable pressure differences occurring in the neighboring chambers or falling below the dew point in the regenerators.

Bekanntlich kann dieses Problem bei Verkokungsofenbatterien mit längsgeteilten Regeneratoren dadurch gelöst werden, daß man die Trennwand im Regenerator, die diesen in das Gas- und Luftabteil auftrennt, entsprechend verschiebt.As is known, this problem can be solved in coking furnace batteries with slit regenerators by moving the partition in the regenerator, which separates it into the gas and air compartment, accordingly.

Erfindungsgemäß werden bei Verkokungsofenbatterien mit halbgeteilten Regeneratoren und Oberöfen mit gleichen Mittenabständen solche Unteröfen verwendet, die in abwechselnder Reihenfolge ungleiche Breiten haben, wobei zwei benachbarte Unteröfen zusammen dieselbe Breite haben wie zwei Oberöfen. Unter Oberofen sei der Teil zwischen Ofensohle und Oberkante Ofendecke verstanden und unter dem Unterofen der Teil zwischen Ofensohle und Fundament. Ferner sollen die Mittellinien der Unteröfen (Regeneratoren) mit den Mittellinien der darüber befindlichen Ofenkammern lotrecht fluchten. Die Trennwände der Regeneratoren sollen dabei normalerweise gleich dick ausgeführt werden, während die lichten Regeneratorkammerbreiten ungleich sind.According to the invention, coking furnace batteries with half-split regenerators and upper furnaces with the same center distances are used such sub-furnaces which have different widths in alternating order, with two neighboring sub-furnaces together having the same width as two upper furnaces. The upper furnace is the part between the furnace sole and the upper edge of the furnace roof and the lower furnace is the part between the furnace sole and the foundation. Furthermore, the center lines of the sub-furnaces (regenerators) should be aligned perpendicularly with the center lines of the furnace chambers located above. The partition walls of the regenerators should normally be of the same thickness, while the clear regenerator chamber widths are not the same.

Erfindungsgemäß werden die Schwachgasregeneratoren breiter als die Luftregeneratoren ausgeführt, wobei das Breitenverhältnis maximal dem Mengenverhältnis Schwachgas/Luft entspricht. In letzterem Falle ergeben sich bei der Verwendung gleichwertiger Gittersteine in beiden Kammern gleiche Regeneratorwirkungsgrade und gleiche Druckverhältnisse in beiden Nachbarregeneratoren. Das Verhältnis der lichten Regeneratorkammerbreiten kann aber auch kleiner als das Verhältnis von Gas- zu Luftmengen, jedoch größer 1 : 1 ausgeführt werden. In diesem Falle können entweder leichte Unterschiede hinsichtlich der Regeneratorwirkungsgrade und auch kleine Druckunterschiede zwischen benachbarten Kammern bei Verwendung gleichwertiger Gittersteine auftreten, oder aber es werden Gittersteine in zwei benachbarten Regeneratoren mit unterschiedlichen spezifischen Wärmeaustauschflächen und/oder entsprechenden freien Durchtrittsquerschnitten verwendet. In letzterem Falle wird wiederum erreicht, daß in beiden benachbarten Regeneratoren für Gas- oder Luftaufheizung die Regeneratorwirkungsgrade gleich sind und keine Druckdifferenzen zwischen den beiden Kammern auftreten.According to the invention, the lean gas regenerators are made wider than the air regenerators, the width ratio corresponding at most to the lean gas / air ratio. In the latter case, the use of equivalent grid stones in both chambers results in the same regenerator efficiencies and the same pressure ratios in both neighboring regenerators. The ratio of the clear regenerator chamber widths can, however, also be made smaller than the ratio of gas to air quantities, but larger than 1: 1. In this case, either slight differences in regenerator efficiencies and also small pressure differences between adjacent chambers can occur when using equivalent lattices, or lattices are used in two adjacent regenerators with different specific heat exchange surfaces and / or corresponding free passage cross sections. In the latter case, it is again achieved that the regenerator efficiencies are the same in both adjacent regenerators for gas or air heating and that no pressure differences occur between the two chambers.

Die Gas- und Luftkanalquerschnitte in den Ofensohlen verhalten sich zueinander zweckmäßig wie die Gas-/Luftmengen. Hierdurch wird verhindert, daß durch unterschiedliche Druckverluste in den Kanälen rückwirkend unterschiedliche Druckverhältnisse in benachbarten Regeneratoren auftreten.The gas and air duct cross sections in the furnace soles behave appropriately to one another like the gas / air quantities. This prevents different pressure ratios in neighboring regenerators from retroactively occurring due to different pressure losses in the channels.

Bei Verwendung eines Unterbrennersystems für Starkgasbeheizung können die vertikalen Gasleitungen mittig oder auch außermittig in den Regeneratortrennwänden angeordnet sein.When using an underburner system for high-gas heating, the vertical gas lines can be arranged in the center or also off-center in the regenerator partition walls.

Die Erfindung ist in der Zeichnung, die einen Teil eines Längsschnittes durch eine Verkokungs-Verbundofenbatterie zeigt, beispielsweise veranschaulicht.The invention is illustrated, for example, in the drawing, which shows part of a longitudinal section through a coking composite oven battery.

In der Zeichnung sind mit 1 die Ofenkammern und mit 2 die dazwischen liegenden Heizwände angedeutet, die zusammen den erwähnten Obero- . fen bilden. Der Unterofen besteht im wesentlichen aus den Regeneratoren und den darunter befindlichen Sohlkanälen. Wie aus der Zeichnung ersichtlich, ist der Regenerator 3 für Luft erfindungsgemäß von geringerer Breite als der Regenerator 4 für Gas. Entsprechend sind die Sohlkanäle 5 für Luft schmaler als die Sohlkanäle 6 für Gas. Die Abmessungen sind hierbei so getroffen, daß zwei Ofenteilungen a die gleiche Breite aufweisen wie die Regeneratorteilung Luft b zuzüglich der Regeneratorteilung Gas c. Die Mittellinien der Regeneratoren fluchten hierbei mit den Mittellinien der darüber befindlichen Ofenkammern.In the drawing, the furnace chambers are indicated by 1 and the heating walls between them, indicated by 2, which together form the aforementioned upper. fen form. The lower furnace consists essentially of the regenerators and the bottom channels below. As can be seen from the drawing, the regenerator 3 for air according to the invention is of smaller width than the regenerator 4 for gas. Correspondingly, the sole channels 5 for air are narrower than the sole channels 6 for gas. The dimensions are such that two furnace divisions a have the same width as the regenerator division air b plus the regenerator division gas c. The center lines of the regenerators are aligned with the center lines of the furnace chambers above.
