Abstract
Description
Verfahren und Vorrichtung zum Einführen von festen Brennstoffen in unter Druck arbeitende Vergaser Die Einführung fester Brennstoffe, wie Steinkohle oder Braunkohle, in unter erhöhtem Druck stehende Vergaser bietet Schwierigkeiten. So ist es z. B. erforderlich, die Kohle ohne Gasverluste in den Vergaser einzubringen. Man hat daher vorgeschlagen, den festen Brennstoff in einer Flüssigkeit aufzuschlämmen und ihn in dieser Form, z. B. mit Hilfe einer Pumpe, dem Vergaser zuzuführen. Nach einem anderen Vorschlag setzt man die in einem Druckbehälter befindliche Kohle mit einem Gas unter Druck und nimmt dann eine Zuteilung in den Vergaser, z. B. mittels Zellenräder, vor. Beide Verfahrensmöglichkeiten sind aufwendig. Die Einführung der Aufschlämmung besitzt ferner den Nachteil, dass die Flüssigkeit zumeist mit erheblichem Wärmeaufwand im Vergaser wieder verdampft, dann kodensiert und im Kreislauf zurückgeführt werden muss. Andererseits besitzt die Einführung mit Hilfe eines unter Druck stehenden Gases den Nachteil, dass Gasverluste in Kauf genommen werden müssen, oder eine Entstaubung und Rekompression des für die Druckhaltung benutzten Gases erfolgen muss.Method and device for introducing solid fuels into pressurized gasifiers The introduction of solid fuels such as coal or lignite, in a gasifier under increased pressure presents difficulties. So it is z. B. necessary to bring the coal into the gasifier without gas losses. It has therefore been proposed to slurry the solid fuel in a liquid and him in this form, e.g. B. with the help of a pump to feed the carburetor. To Another suggestion is to put the coal in a pressure vessel with it a gas under pressure and then takes an allotment into the carburetor, e.g. B. by means of Cell wheels, in front. Both process options are complex. The introduction of the Slurry also has the disadvantage that the liquid mostly with considerable Heat expended in the carburetor evaporated again, then coded and fed back into the circuit must become. On the other hand, the introduction has the help of a pressurized Gas has the disadvantage that gas losses have to be accepted, or dedusting and recompression of the gas used for pressure maintenance got to.
Es wurde nun gefunden, dass man unter Vermeidung der genannten Nachteile feste Brennstoffe in unter Druck arbeitende Vergaser einführen kann, wenn man die Brennstoffe, gegebenenfalls nach einer Vortrocknung und/oder einer Zerkleinerung, in Brikettiervorrichtungen verpresst und die verpressten Brennstoffe unmittelbar dem Vergaser zuführt. Mit Vorteil kann man als Brikettiervorrichtung z. B. die üblichen Strangpressen wählen. In diesen wird die gegebenenfalls vorgetrocknete und nach Erfordernis in bekannter Weise zerkleinerte Kohle verpresst, wobei Drücke bis zu 1000 bar und höher durch entsprechende Ausbildung des Pressenmundes eingestellt werden können.It has now been found that, while avoiding the disadvantages mentioned Can introduce solid fuel into pressurized gasifiers if you have the Fuels, if necessary after pre-drying and / or comminution, pressed in briquetting devices and the pressed fuels directly feeds to the carburetor. Advantageously, you can use as a briquetting z. B. the usual Choose extrusion. In these, the optionally pre-dried and after If required, crushed coal is pressed in a known manner, with pressures up to 1000 bar and higher adjusted by appropriate design of the press mouth can be.
Obschon die Vergasung von Kohle im allgemeinen bei Drücken bis etwa 100 bar durchgeführt wird, können die wesentlich höheren Pressdrücke insbesondere dann von Vorteil sein, wenn ein Vergasungsverfahren für die Verarbeitung stückiger Kohle gewählt wurde.Although the gasification of coal generally at pressures up to about 100 bar is carried out, the significantly higher pressing pressures can in particular then be of advantage when using a gasification process for processing lumpy Coal was chosen.
Die in den Vergaser geführten Presslinge trennen sich leicht voneinander, so dass ihre Förderung zum Vergaser in einfacher Weise erfolgen kann. Selbstverständlich kann der Pressdruck auch niedriger gewählt werden, insbesondere dann, wenn kleinstückigere Kohle, z. B. in der Wirbelschicht, vergast werden soll.Hier wird man den Druck nur so hoch wählen, dass durch die Reibungskräfte der verpressten Kohle an der Pressenwand ein ausreichend gasdichter Abschluss gewährleistet ist. Die gepresste Kohle wird vom Pressenmund unmittelbar in den Vergaser geleitet. Je nach Grösse und Leistung des Vergasers wird man eine oder mehrere Brikettiervorrichtungen wählen, die z. B. sternförmig um den Vergaser angebracht Werden. Die Pressen können in der Höhe der Kohleeinführung angebracht werden, aber z. B. auch am Fuss des Vergasers.The pellets fed into the carburetor separate easily from each other, so that they can be conveyed to the carburetor in a simple manner. Of course the pressing pressure can also be selected to be lower, especially when smaller pieces Coal, e.g. B. in the fluidized bed, is to be gasified. Here one is only the pressure choose so high that the frictional forces of the compressed coal on the press wall a sufficiently gas-tight seal is guaranteed. The pressed coal is made from the press mouth directly into the carburetor. Depending on size and Capacity of the gasifier one or more briquetting devices will be selected, the z. B. in a star shape around the carburetor. The presses can be in the Height of the coal inlet can be attached, but z. B. also at the foot of the carburetor.
In diesem Fall wird die verpresste Kohle durch Rohrleitungen an die Einführungsstelle gebracht. Insbesondere beim Einsatz von Braunkohle bietet das erfindungsgemässe Verfahren Vorteile, weil die sonst notwendige getrennt vorgenommene Brikettierung und die Einschleusung in den Vergaser jetzt in einem Arbeitsgang durchgeführt werden können.In this case, the compressed coal is connected to the Introductory site brought. This is particularly useful when using lignite inventive method advantages, because the otherwise necessary carried out separately Briquetting and the introduction into the carburetor are now carried out in one operation can be.
In der Zeichnung'ist eine Ausführungsform des erfindungsgemässen Verfahrens beispielhaft gezeigt.The drawing shows an embodiment of the method according to the invention shown as an example.
Aus dem Behälter 1 wird zerkleinerte Braunkohle in üblicher Weise der Strangpresse 2 zugegeben, mit deren Stempel 3 die Kohle im Kanal 8 zum Pressenmund 4 verdichtet wird. Unter der Einwirkung der Stempelbewegungen werden die Presslinge durch das unter dem im Vergasungsraum 6 herrschenden Druck stehende Rohr in den Vergasungsraum 6 befördert. Das Rohr 5 ist zur Presse 2 hin durch die im Kanal 8 und im Pressenmund 4 befindliche, bereits gepresste Kohle abgeschlossen. Mit Hilfe des Schiebers 7 kann das Rohr 5 zum Vergaser hin geschlossen werden, so dass gegebenenfalls Reparaturarbeiten an der Presse möglich sind, ohne den Vergaser abstellen zu müssen.Crushed lignite is made from the container 1 in the usual way the extruder 2 added, with the stamp 3 of the coal in the channel 8 to the press mouth 4 is compressed. The compacts are under the action of the punch movements through the pressure prevailing in the gasification chamber 6 into the pipe Gassing room 6 promoted. The tube 5 is towards the press 2 through the channel 8 and already pressed coal located in the press mouth 4 is completed. With help of the slide 7, the pipe 5 can be closed towards the carburetor, so that if necessary Repair work on the press is possible without having to turn off the carburetor.
