132562 KLASSE 26«.132562 CLASS 26 «.
Kohlenklein, Sägespäne, Torf und anderer Brennstoff, in dem sich gröbere Stücke neben Gries oder Mehl vorfinden, lassen sich bis heute nur sehr schwer auf Kohlenoxyd (Generatorgas) verarbeiten. In einigen Fällen lä'fst sich zwar noch mit gewissem Erfolge der Schrägrost, in anderen eine Generatorbauart anwenden, die den zum Rösten pulverförmiger Erze gebräuchlichen Oefen ähnlich sieht, trotzdem bleiben aber noch grofse Mengen von Brennstoff, die sich überhaupt nicht verwenden lassen, wenn man nicht das kostspielige Briquettiren zu Hülfe nimmt.Coal, sawdust, peat and other fuel in which coarser pieces are next to To find semolina or flour, it is still very difficult to use carbon oxide (generator gas) to process. In some cases the inclined grate can still be used with a certain degree of success, in others a generator design use, which looks similar to the ovens commonly used for roasting powdered ores, nevertheless but there are still large quantities of fuel that cannot be used at all leave if one does not use the expensive briquetting to help.
Hierhin gehören in erster Linie die beim Sieben und Waschen der Kohlen entstehenden Rückstände, welche einen so hohen Gehalt an feinem Staub besitzen, zum Theil sogar ausschliefslich daraus bestehen, dafs eine grofse Menge beim Durchblasen unzersetzt vom Gasstrome mitgeführt wird. Diese Erscheinung, die bei allen bisherigen Verfahren lästig empfunden und der mit den verschiedensten Mitteln vergeblich abzuhelfen versucht wurde, bildet den Ausgangspunkt vorliegenden Verfahrens. Nach diesem trennt man den zu verarbeitenden Brennstoff in Grobes und Feines. Ersteres führt man in eine sich drehende Trommel (Blechcylinder mit innerer Ausfütterung aus feuerfesten Steinen) ein, welche es infolge ihrer Drehung und geneigten Lagerung oder kegelartigen Form der Länge nach durchläuft. An dem der Aufgabestelle des Groben entgegengesetzten Trommelende tritt das feine Brennmaterial mit der Verbrennungsluft ein und wird entzündet, wie bei den Kohlenstaubfeuerungen bekannter Bauart. Die entstandene Kohlensäure durchstreicht die Trommel in einem zur Fortgangsrichtung des Groben entgegengesetzten Sinne, kommt dabei mit letzterem in Berührung und wird zu Kohlenoxydgas. reducirt. Um die Reduction durch Vergröfserung der Berührungsfläche zu erleichtern, sind im Innern der Trommel schaufelartige Vorsprünge aus feuerfestem Stoff angebracht, die das Grobe bei jeder Drehung mit hoch nehmen.This includes primarily those produced by sieving and washing the coals Residues, which have such a high content of fine dust, in part even exclusively consist of the fact that a large quantity, when blown through, is undecomposed by the gas stream is carried. This phenomenon, which has been annoying in all previous procedures and which has been tried in vain to remedy the situation with the most varied of means, forms the starting point of the present proceedings. After this, the fuel to be processed is separated into coarse and fine. The former is fed into a rotating drum (sheet metal cylinder with inner lining made of refractory bricks), which is due to their rotation and inclined position or cone-like shape running through the length. At the point of application of the rough At the opposite end of the drum, the fine fuel enters with the combustion air and is ignited, as in the known type of pulverized coal combustion. The resulting Carbon dioxide sweeps through the drum in a direction opposite to the direction of progress of the coarse Senses, comes into contact with the latter and becomes carbon oxide gas. reduced. About the reduction through enlargement To facilitate the contact surface are shovel-like inside the drum Fireproof tabs attached that keep the rough with every turn with high to take.
Sieht man von dem beim Rollen des Groben gebildeten Staub ab, der aber auch nur zum Theil von den Gasen entfernt wird, so erhellt, dafs nur ganz geringe Verluste durch mitgerissenen Staub entstehen.If you disregard the dust formed when rolling the coarse, but only for the If part of the gases is removed, it is evident that only very slight losses result from it entrained dust is created.
Ein anderer Vortheil ist die vorzügliche Reduction, bedingt durch sehr hohe Temperatur und genügend lange Berührung der Kohlensäure mit dem Groben. Weil man hier nämlich nicht auf einen Luftüberschufs zu sehen braucht, da doch Kohlenoxyd das Endproduct ist, stellt man die Staubfeuerung auf die höchste Temperatur ein. Dann ist die Flamme, deren gesammte Wärme hier im Gegensatz zur Rostfeuerung nutzbar gemacht wird, so heifs, dafs sie das Trommelinnere und das grobe Brennmaterial auf eine Strecke von mehreren Metern auf über 10000 erhitzt, wobei die Reduction der Kohlensäure sich glatt vollzieht. Will man die in den Gasen enthaltene Wärme noch intensiver zum Vorwärmen des Groben ausnutzen, so legt man am besten eine Trommel vor, die für diesen Zweck besonders gebaut ist. Solches zeigtAnother advantage is the excellent reduction, due to the very high temperature and long enough contact of the carbonic acid with the coarse. Because you don't need to look at excess air here, since carbon oxide is the end product, you set the dust furnace to the highest temperature. Then the flame whose entire heat is in contrast to grate made here available, so remains hot, that they the drum interior and the coarse fuel to a distance of several meters to over 1000 0 heated, with the reduction of carbon dioxide is taking place smoothly. If you want to use the heat contained in the gases even more intensively to preheat the coarse, it is best to put a drum in front of it that is specially built for this purpose. Such shows
sich aber nur für diejenigen Fälle zweckmä'fsig, wo der Procentgehalt an Staub niedrig ist.but only useful in those cases where the percentage of dust is low.
Aus dem Gesagten ist der grundsätzliche Unterschied zwischen dem vorliegenden und dem von Bletzinger (Zeitschrift des Vereins deutscher Ingenieure 1892, Seite 23) vorgeschlagenen Verfahren ersichtlich. Dort wird in eine sich drehende, schräg gelagerte Trommel ähnlicher Bauart der gesammte Brennstoff am oberen Ende aufgegeben und durch am anderen Ende einströmende Luft in Kohlenoxyd verwandelt. Die dabei vorhandenen Nachtheile der sehr schwer erfolgenden Kohlensäurebildung, der damit verbundenen niederen Temperatur (»kalter Gang« des Generators) und des Wegführens von Staub werden beim vorliegenden Verfahren beseitigt.From what has been said is the fundamental difference between the present and that proposed by Bletzinger (Journal of the Association of German Engineers 1892, page 23) Procedure evident. There is in a rotating, inclined drum similar design abandoned the entire fuel at the top and through at the other At the end of the inflowing air, transformed into carbon monoxide. The disadvantages involved the very difficult carbonic acid formation, the associated low temperature ("cold gear" of the generator) and dust removal are eliminated with the present method.
