Zusatz zum Patent 311073.Addition to patent 311073.

Patentiert im Deutschen Reiche vom 8. Mai 1917 ab. Längste Dauer: 7. August 1931.Patented in the German Empire on May 8, 1917. Longest duration: August 7, 1931.

Gegenstand des Hauptpatentes 311073 ist ein Verfahren nebst Vorrichtung zur Erzeugung von Leuchtgas sowie von Kraftgas neben wertvollem Koks in einem Ofen. In einem in seinem unteren Teile generatorartig ausgebildeten Schachtofen erfolgt die Entgasung des kohlenstoffhaltigen Gutes durch die strahlende Wärme, wie auch durch die heißen Gase des Generators, wobei die Erhitzung der Kohle usw. nur so weit getrieben wird, daß völlige Verkokung erfolgt, während nach Beendigung der Kokungsperiode durch stärkeres Blasen des Generators mit Luft oder Dampf die Entgasung völlig beendet wird. Bei der im Hauptpatent beschriebenen Vorrichtung hat sich nun gezeigt, daß die Verarbeitung solcher' Kohle (oder anderen kohlenstoffhaltigen Gutes), welche beim Verkoken stark zusammenbackt, mit gewissen Schwierigkeiten verbunden ist.The subject of main patent 311073 is a method and device for generating luminous gas and fuel gas in addition precious coke in an oven. In one designed like a generator in its lower part In the shaft furnace, the carbonaceous material is degassed by the radiant Heat, as well as by the hot gases from the generator, heating the coal etc. is only driven so far that complete coking takes place, while after completion degassing during the coking period by blowing the generator more strongly with air or steam is completely terminated. In the device described in the main patent has now shown that the processing of such 'coal (or other carbonaceous goods), which caked strongly during coking, is associated with certain difficulties.

Man muß bei solchem Gut dafür sorgen, daß der Koks sowohl in dem Generatorteil gut und leicht nachrutscht, wie auch daß der im Ofenraum gebildete und zu gewinnende Koks aus dem Ofen leicht entfernt werden kann. Dies ist bei der Vorrichtung des Hauptpatentes nicht immer glatt ausführbar; die Schwierigkeiten lassen sich aber leicht beseitigen durch den Gegenstand vorliegender Erfindung. Dieser betrifft in erster Linie eine Vorrichtung, bei der Generator- und Ofenteil senkrecht nebeneinander angeordnet sind, wobei der Ofenteil sich nach unten zu etwas konisch erweitert. Beide Teile der Vorrichtung sind voneinander entweder durch rippenartig durchbrochene oder durch volle Querwände teilweise getrennt, derart, daß diese Rippen oder Querwände bis über die halbe Höhe des Ofenteiles hinanreichen, während im oberen Teile Generator- und Ofenraum miteinander frei verbunden bleiben.With such a good one must ensure that the coke in the generator part is good and easily slips, as well as that the coke formed in the furnace space and to be extracted from can be easily removed from the oven. This is the case with the device of the main patent not always smoothly executable; but the difficulties can easily be eliminated through the subject matter of the present invention. This primarily concerns a device in the generator and furnace part are arranged vertically next to each other, the The oven part widens conically towards the bottom. Both parts of the device are from each other either through rib-like perforated or partially through full transverse walls separated in such a way that these ribs or transverse walls up to over half the height of the furnace part while the generator and furnace areas remain freely connected to one another in the upper part.

Die Vorrichtung ist in Fig. 1 in einer Ausführungsform, in Fig. 2 in einer anderen Ausführungsform im senkrechten Schnitt dargestellt. In Fig. ι bezeichnet 1 den Generatorteil mit dem Rost 3; 2, 2 bezeichnet den Ofenteil, der von 1 durch Rippen oder durchbrochene Wände 8 teilweise getrennt ist. Der in 2 gebildete Koks kann sich bei dieser Vorrichtung von dem im Generatorteil befindlichen leicht ablösen und wird beim öffnen der Entleerungstüren 7, 7 ohne jede Schwierigkeit herausgleiten und sich so bequem entnehmen lassen; dies wird noch durch die nach unten schwach konisch erweiterte Gestalt des Ofenraumes befördert. In gleicher Weise kann das im Generatorraum 1, der also schachtartig von senkrechten Flächen begrenzt ist, befindliche Feuerungsmaterial, der Vergasung der unteren Schichten folgend, leicht nachrutschen.The device is shown in Fig. 1 in an embodiment, shown in Fig. 2 in another embodiment in vertical section. In Fig. Ι 1 denotes the generator part with the grate 3; 2, 2 designates the furnace part which is partially separated from 1 by ribs or perforated walls 8. Of the In this device, coke formed in 2 can come from that located in the generator part easy to peel off and is without any difficulty when opening the emptying doors 7, 7 slide out and can be easily removed; this is made even more by the after The shape of the furnace chamber is slightly widened conically at the bottom. In the same way can do this in the generator room 1, which is bounded by vertical surfaces like a shaft is the combustion material located, following the gasification of the lower layers, light slide down.

Für den Ofen- und Generatorraum sind besondere Einfüllvorrichtungen 4, 4 und 5 vorgesehen. Durch diese Anordnung wird auch ermöglicht, von vornherein die beiden Special filling devices 4, 4 and 5 are provided for the furnace and generator room. This arrangement also enables the two from the outset

Claims

To fill rooms with various goods. For example, the furnace chamber can be filled with the goods to be degassed (hard coal, brown coal, wood, peat, slate, animal or vegetable waste of all kinds, etc.), while the generator room, for example, with! Lean coal, brown coal, briquettes or coke can be charged. At 6, 6 are the gas exhausts for the to be obtained: ίο light and power gas. Fig. 3 shows a section through the line A-B. As can be seen from this, the heat transfer by radiation, such as by the hot generator gas, can take place to a sufficient extent through the spaces remaining between 8, 8. A second embodiment of the device for carrying out the method is shown in FIG. Fig. 4 shows this in a section through the line B-C. With this arrangement, the gas outlets at the lower end of the furnace chamber are not far above the emptying doors J, "J. j In the latter case, the heat transfer to the coal to be degassed etc. takes place essentially through the hot generator gases rising in the generator chamber 1 , enter the furnace chamber 2, 2 over the upper ends of the transverse walls and pass through the material to be degassed going downwards. In both devices described above, the mode of operation and the process is exactly the same as described in the main patent the filling of the lower exposed part of the generator space is blown hot and the entire furnace is thus heated up, coal j or possibly another generator heated material is filled through the filling openings 4, 4 and 5 in 5. Then, by gently blowing in Air, with or without the addition of steam, under the grate 3 a weak stream of very hot G generated energy gas, which sweeps through the material to be degassed and, in combination with the radiant heat of the generator filling and the furnace wall, quickly brings it to the temperature required for degassing. A high-heat gas is formed in addition to a lot of tar and ammonia, and degassing takes place in a short time as a result of the direct heat transfer. The resulting luminous gas is fed through one of the two outlet lines 6 to the cleaner and then used again. After the actual degassing has ended, a strong flow of very hot gases with a lower calorific value is generated by blowing in more air and steam, which can be discharged through the other gas outlet 4 and used as fuel or heating gas. During these processes the contents of the furnace are heated so high that complete coking occurs. The coke obtained is withdrawn through the discharge doors 7, 7, and the process described takes place again. The two devices described also have the following advantages: Low system costs , increased yield of gas, tar and ammonia, low consumption of underfiring and simultaneous generation of a heating gas that can be used for power and heating requirements of the degassing system.
