Verfahren zum Betriebe von Gasschachtöfell.

zu verteilen.
Ebenso ergeben sich beim Betriebe der verschiedenen Schachtöfen mit Mischfeuerung Schwierigkeiten in der Richtung, dass es nicht möglich ist, die Leistung des Ofens in weitgehendem Masse zu regeln. Die Folge einer zu weitgehenden Drosselung ist ein nicht durchgebrannte Gut. Die Ursache ist auch hier dieselbe. Sobald nämlich der Luftstrom unter ein gewisses Mass herabsinkt, füllt er nicht mehr den vollen Ofenquerschnitt aus, wodurch eine ungleichmässige Verbrennung bedingt ist.
Wenn man nun Gas bzw. Luft nicht in kontinuierlichem Strome, sondern stossweise dem Ofen zuführt, ist es einerseits möglich, die mit dem einzelnen Stosse zugeführte Gas-und Luftmenge so gross zu wählen, dass eine ausreichende Verteilung derselben über den ganzen Ofenquerschnitt erreicht wird, anderseits aber ist es möglich, durch entsprechende Wahl der Strömungspausen das dem Ofen überhaupt zugeführte Gas-und Luftquantum so weit herabzudrücken, wie es der ökonomische Ofenbetrieb verlangt.
Selbstverständlich kann die stossweise Zuführung der Verbrennungsluft auch beim Gasofen in Betracht kommen. Ein gleichmässiger Gang des Gasgenerators kann beim Gasofen trotz der stossweisen Gaszufuhr dadurch erreicht werden, dass die Gaseinströmungen nicht alle gleichzeitig, sondern abwechselnd gedrosselt werden und in die Gasleitung ein Pufferbehälter eingebaut wird.

Procedure for operating gas shafts.
EMI1.1
to distribute.
Likewise, when operating the various shaft furnaces with mixed firing, difficulties arise in the direction that it is not possible to control the output of the furnace to a large extent. If the throttling is too extensive, the product is not burned out. The cause is the same here too. As soon as the air flow drops below a certain level, it no longer fills the full cross-section of the furnace, which results in uneven combustion.
If the gas or air is not fed into the furnace in a continuous stream, but in bursts, it is possible, on the one hand, to select the amount of gas and air supplied with the individual burst so large that it is adequately distributed over the entire furnace cross-section, on the other hand, however, it is possible, by appropriate selection of the flow pauses, to reduce the amount of gas and air supplied to the furnace as far as economic furnace operation requires.
Of course, the intermittent supply of combustion air can also be considered in the gas furnace. A steady operation of the gas generator can be achieved in the gas furnace in spite of the intermittent gas supply in that the gas inflows are not all throttled at the same time, but alternately and a buffer container is installed in the gas line.
