Description

Verfahren zum Herstellen von Wassergas und Generatorgas in einer Schicht von feinkörnigem Brennstoff Durch das Hauptpatent 437 970 ist ein Verfahren zum Herstellen von Wassergas geschützt, bei welchem die Vergasungsmittel derartig von unten in den Gaserzeuger eingeblasen werden, daß sich der feinkörnige Brennstoff in der ganzen Schichthöhe in einer auf und ab wirbelnden Bewegung befindet. Die Vergasungsmittel werden zu diesem Zweck unter Druck in die Brennstoffschicht eingeführt.A process for the manufacture of water gas and generator gas in a layer of fine-grained fuel through the main patent 437,970 a method is protected for the manufacture of water gas, wherein the gasification agent are such blown from below into the gas generator, that the fine-grained fuel throughout the bed height in an up and down swirling motion. For this purpose, the gasification agents are introduced into the fuel layer under pressure.

Es wurde nun gefunden, daß man ebenfalls vorteilhaft arbeiten und sowohl Wassergas als auch Gener atorgas herstellen kann, wenn man die Vergasungsmittel, statt sie in den Gaserzeuger einzublasen, in diesen einsaugt. Das neue Verfahren hat verschiedene Vorteile. Es ist beispielsweise unnötig, eine geschlossene Rostkammer anzubringen. Der Rost kann unten sogar völlig frei liegen und ist daher für Ausbesserungen leicht zugänglich. Er kann z. B. auf Rollen verschiebbar eingerichtet werden, so daß der unter der glühenden Kohle befindliche Teil zur Entfernung der Schlacke jederzeit nach außen gezogen werden kann. Es ist zweckmäßig, unter dem Rost eine leicht entfernbare flache Kammer, die mit Öffnungen für den Eintritt der angesaugten Luft bzw. des Wasserdampfes versehen ist, anzubringen. Es kann auch gleichzeitig mit der Luft feiner Kohlenstaub durch den Rost eingesaugt werden, der in dem glühenden Kohlenbett unter teilweiser Ersparnis körniger Kohle vergast. Diese Staubeinführung wäre bei einer geschlossenen Rostkammer, in die die Luft unter Druck eingeführt wird, gefährlich, da im Falle einer Staubexplosion die Kammer leicht zerstört werden könnte, während im vorliegenden Falle eine Explosion ohne Schaden verläuft.It has now been found that one can also work advantageously and can produce both water gas and generator gas if one uses the gasification agents, instead of blowing them into the gas generator, sucking them into it. The new procedure has several advantages. For example, it is unnecessary to have a closed grate chamber to attach. The rust can even be completely exposed at the bottom and is therefore suitable for repairs easily accessible. He can z. B. be set up movable on rollers, so that the part located under the glowing coal to remove the slag at any time can be pulled outwards. It is useful to have an easily removable one under the grate flat chamber with openings for the inlet of the sucked air or the Is provided with water vapor. It can also be simultaneous with the air Fine coal dust is sucked in through the grate, which is in the glowing coal bed gasified with partial saving of granular coal. This dust introduction would be at a closed grate chamber, into which the air is introduced under pressure, dangerous, since in the event of a dust explosion the chamber could easily be destroyed while in the present case an explosion proceeds without damage.

In der Abbildung, die im Ausführungsbeispiel dargestellt, ist A ein Gaserzeuger mit 4 qtn Querschnitt, B ein Kühlturm für das Gas und C das Gebläse, dessen Saugseite an den Kühlturm B angeschlossen ist. Der Gaserzeuger A ist unten mit einem waagerecht verschiebbaren Rost D versehen, an dem der ebenfalls verschiebbar angeordnete Rostlasten E hängt. In dem Rostkasten sind öffnungen für die einzusaugende Luft sowie eine Öffnung für ein Dampfrohr, das den Dampf für das Wassergas liefert, vorgesehen. Bei Inbetriebnahme wird folgendermaßen verfahren: Durch die Schnecke F werden 3 cbm glühende Grude eingeführt und dabei das Gebläse C derartig betrieben, daß es stündlich etwa 400 cbm Luft durch den Rost D saugt. Die auf den Rost gelangende glühende Grude verteilt sich augenblicklich über den ganzen Rost und gerät unter der Einwirkung der durchgesaugten Luft in auf und ab wirbelnde B ew egung. Hat die Kohlenfüllunu rund goo' erreicht, dann wird durch die Schnecke F stetig mulmige Braunkohle mit io"/" Wasser, und zwar stündlich in einer Menge von 3,2 t eingedreht. Durch die Luftdüsen G läßt man weitere 4000 cbm Luft eintreten, wodurch insbesondere der aufgewirbelte Staub vergast wird. Das entstehende Gas, das 7 "J" C0_, 2i"/" CO, i2°/" H2, i°/" CH-, enthält, wird in B durch Einspritzen von Wasser gekühlt.In the figure shown in the exemplary embodiment, A is a Gas generator with 4 qtn cross-section, B a cooling tower for the gas and C the fan, whose suction side is connected to the cooling tower B. Gas generator A is down provided with a horizontally movable grate D, on which the can also be moved arranged grate loads E depends. In the grate box there are openings for the to be sucked in Air and an opening for a steam pipe that supplies the steam for the water gas, intended. The procedure for commissioning is as follows: Through the screw F 3 cbm of glowing green are introduced and the fan C is operated in such a way that that it sucks about 400 cubic meters of air through grate D every hour. The one on the grate Glowing Grude instantly spreads over the whole grate and gets underneath the effect of the air sucked through in up and down swirling motion. Has the Coal filling around goo 'is reached, then the snail F is constantly queasy Brown coal with 10 "/" water, turned in every hour in an amount of 3.2 t. A further 4000 cbm of air is allowed to enter through the air nozzles G, which in particular the raised dust is gassed. The resulting gas, the 7 "J" C0_, 2i "/" CO, i2 ° / "H2, i ° /" CH-, is cooled in B by injecting water.

Beim Herstellen von Wassergas wird eine größere Kohlenmenge auf einmal in den Gaserzeuger eingedreht. Die Kohlenfüllung wird bis auf rund iioo° heißgeblasen und dann Dampf eingesaugt. Wenn die Kohlentemperatur auf goo° gesunken ist, wird der Dampf abgestellt, von neuem Luft durchgesaugt und gleichzeitig Kohle eingedreht.When producing water gas, a larger amount of coal is used at one time screwed into the gas generator. The charcoal filling is blown hot to around 100 degrees and then sucked in steam. When the coal temperature has dropped to goo °, will the steam turned off, fresh air sucked through and coal rolled in at the same time.
