die Lfitung d juid die Verlage c nach aussen gefülurt. Gleichzeitig mit dem Dampfstrom wirdund dieses bildet das Wesentliche bei dem vorliegenden Verfahren - neben dem Dampfstrom durch die Düsen f Verbrejmungsluft in den Schacht eingeführt. Hiedurch wird ein geringer Teil des Wassergases verbrannt, dafür die Entgasungstemperatur aber wesentlich erhöht, so dass die über der aus Koks bestehenden Brennstoffsäule befindliche Brennstoffmasse bei gleichzeitiger Ein wirkung des von unten aufsteigenden heissen Wassergases wirkungsvoll und schnell ver- kokt wird.
Das Verfahren bietet gleichzeitig die Möglichkeit, durch eine ganz geringe Verminderung der erzeugten Gasqualität besonders die Ammoniakgewinnung zu verbessern. Durch das Einblasen von Verbrennungsluft kann nicht nur die zusätzliche Wärmemenge zur Entgasung der oberen Brennstoftsäule erzeugt werden, sondern es ist ohneweiters möglich, die Menge der Ver- brennungsluit derart zu vergrössern, dass die zur Entgasung erforderliche Temperatur auch dann noch erhalten werden kann, wenn neben der Verbrennungsluft oder mit derselben oberhalb der Kokssäule auch noch frischer, also verhältnismässig kalter Wasserdampf zur Erzeugung des für die Ammoniakgewinnung erforderlichen Dampfüberschusses eingeführt wird.
Das Verfahren
EMI2.1
gleichzeitig oberhalb der Wassergas erzeugenden Kokszone sowohl Verbrennungsluft als auch sekundärer Wasserdampf eingeführt wird und zwar m solchen Volumverhältnissen, dass infolge der Eingentemperatur des aufwärtsströmenden Wassergases und der durch die Einführung der Luft erzeugten Verbrennung eine solche Temperatur vorhanden ist. dass die obere Brennstcf- säule wirkungsvoll entgast und gleichzeitig der durch die Einführung des Dampfes entstehende Wärmeverlust ausgeglichen wird. Diese Benutzung des Wasserdampfes besitzt den weiteren Vorteil, dass sich bis in die Nähe der Einblasedüsen nur eine mürbe Schlacke bilden kann.

die Lfitung d juid the publishers c led to the outside world. Simultaneously with the steam flow, and this forms the essence of the present process, in addition to the steam flow, combustion air is introduced into the shaft through the nozzles f. As a result, a small part of the water gas is burned, but the degassing temperature is increased significantly, so that the fuel mass located above the fuel column consisting of coke is effectively and quickly coked with simultaneous action of the hot water gas rising from below.
At the same time, the process offers the possibility of improving ammonia production in particular by slightly reducing the gas quality produced. By blowing in combustion air, not only can the additional amount of heat for degassing the upper fuel column be generated, but it is also possible to increase the amount of combustion air in such a way that the temperature required for degassing can still be maintained when in addition to the combustion air or with the same above the coke column also even fresh, i.e. relatively cold water vapor is introduced to generate the excess steam required for ammonia production.
The procedure
EMI2.1
At the same time, above the coke zone generating water gas, both combustion air and secondary steam are introduced in such volume ratios that such a temperature is present as a result of the temperature of the water gas flowing upwards and the combustion generated by the introduction of the air. that the upper fuel column is effectively degassed and at the same time the loss of heat caused by the introduction of steam is compensated. This use of the steam has the further advantage that only a crumbly slag can form up to the vicinity of the injection nozzles.
