Description
Verfahren zum Brennen mit Gas im Schachtofen. Es ist bekannt, das Gas vor Eintritt in den Schacht mit aus der Kühlzone angesaugter Luft zu verbrennen. Dabei läßt sich nicht vermeiden, daß ein Teil der Luft unmittelbar durch das Gut nach oben geht. Ebenso ist es bekannt, die Luft in Kanälen, die in der Schachtwandung liegen oder in einem für alle Brenner gemeinsamen, innerhalb des Schachtes liegenden Rekuperator zu erwärmen. Die, Nachteile dieser Konstruktionen liegen darin, daß keine wirksame Erhitzung der Luft erzielt wird bzw. keine genaue Einstellung der Gas- und Luftzufuhr zu den einzelnen Brennern möglich ist, da sie sich infolge des gemeinsamen Rekuperators gegenseitig beeinflussen.Method of burning with gas in a shaft furnace. It is known that Burn the gas with air drawn in from the cooling zone before it enters the shaft. It cannot be avoided that part of the air flows directly through the material goes up. It is also known that the air in ducts in the shaft wall or in a common for all burners, located within the shaft To heat the recuperator. The disadvantages of these designs are that no effective heating of the air is achieved or no precise setting of the Gas and air supply to the individual burners is possible, as they are due to the common recuperators influence each other.
Nach der Erfindung werden die Nachteile dadurch vermieden, daß für jeden Brenner ein besonderer, innerhalb des Schachtes liegender Rekuperator für Luft bzw. für Gas oder für beides mit entsprechenden Regelvorrichtungen vorhanden ist. Die Zeichnung zeigt einen solchen Ofen, bei dem die Luft in Rekuperatoren durch den gebrannten Kalk erhitzt wird.According to the invention, the disadvantages are avoided in that for a special recuperator located within the shaft for each burner Air or for gas or for both with appropriate control devices available is. The drawing shows such a furnace, in which the air in recuperators through the quick lime is heated.
r ist der Schachtofen, 2 die Gasleitung, 3 die Gasdüsen, q. die Lufteintrittsstellen, 5 die in -den Kühlschacht eingebauten eisernen JZekuperatoren. Das zweckmäßig unter Druck eintretende Gas saugt die Luft durch den dazugehörigen Rekuperator und verbrennt vor dem Eintritt in den Ofenschacht. Zu jeder Brennerstelle gehört ein besonderer IZekuperator. In ähnlicher Weise kann das Gas durch Rekuperatoren, die von den abziehenden Rauchgasen umspült werden, erhitzt werden. Die Anordnung kann auch so sein, daß die Rekuperatoren für Luft durch ciie Rauchgase, die Rekuperatoren für Gas durch den gebrannten Kalk bzw. die Rauchgase erhitzt werden.r is the shaft furnace, 2 the gas pipe, 3 the gas nozzles, q. the air inlets, 5 the iron JZekuperators built into the cooling shaft. That useful under Gas entering under pressure sucks the air through the associated recuperator and burns it before entering the furnace shaft. Each burner point has a special one IZekuperator. In a similar way, the gas can pass through recuperators, which are used by the withdrawing ones Flue gases are washed around, are heated. The arrangement can also be such that the recuperators for air through ciie flue gases, the recuperators for gas through the quick lime or the flue gases are heated.
Die vollkommene Vorverbrennung, die irian so erhält, ermöglicht, anstatt einer Reihe von . Brennern mehrere übereinander än%uordnen. Das Verfahren ermöglicht eine vollkommene Ausnutzung der im gebrannten Kalk und den Rauchgasen enthaltenen Wärme und eine genaue Einstellung von Luft und Gas.The perfect pre-combustion that irian gets so enables, instead a number of. Arrange several burners on top of each other. The procedure enables a complete utilization of those contained in the quick lime and the flue gases Heat and an accurate adjustment of air and gas.
