Description
Verfahren zum Vergasen von feinkörnigen Brennstoffen Die Erfindung .betrifft die diskontinuierliche Vergasung feinkörniger Brennstoffe mit periodischer Aufbereitung des Brennstoffbettes. Das Abwärtsgasen oder Blasen geschieht bei ruhendem Brennstoffbett. Die periodische Aufbereitung geschieht in der "'eise, daß inerte Gase, die auch teilweise oder ganz durch Vergasungsmittel (Luft, Sauerstoff, Dampf, Kohlensäure, Brenngase, Wälzgase) ersetzt werden können, von unten her das heiße Kohlenbett in wallende Bewegung bringen, wobei die frisch in das Kohlenbett eintretende Kohle getrocknet, geschwelt und entgast wird und die Schweldämpfe und Wasserdämpfe sich dem in der Aufwärtsperiode entstehenden Gas beimengen. Der hohe Staub- und Teergehalt der Aufwärtsgase ist unerwünscht, da er zu große Schwierigkeiten in der Aufbereitung macht.Method for gasifying fine-grain fuels The invention . concerns the discontinuous gasification of fine-grain fuels with periodic Preparation of the fuel bed. The downward gassing or blowing occurs when the vehicle is at rest Fuel bed. The periodic processing takes place in the "ice that inert Gases that are partially or completely caused by gasification agents (air, oxygen, steam, Carbon dioxide, fuel gases, circulating gases) can be replaced, the hot one from below Bring the coal bed into flowing motion, the freshly entering the coal bed Coal is dried, smoldered and degassed and the smoldering vapors and water vapors add to the gas produced in the upward period. The high dust and The tar content of the upward gases is undesirable as it causes great difficulty in the Processing makes.
Es wurde nun gefunden, daß sich diese Schwierigkeit in einfacher Weise dadurch beheben läßt, daß das mit Staub und Schweldämpfen verunreinigte und gegebenenfalls mit Wasserdampf oder inerten Gasen verdünnte Aufwärtsgas die Glutzone eines zweiten Gaserzeugers während dessen Abwärtsperiode passiert. Dabei wird der Staub zurückgehalten und vergast, die Schweldämpfe werden gekrackt und der Wasserdampf weitgehend zersetzt.It has now been found that this difficulty can be solved in a simple manner can thereby remedy that the contaminated with dust and smoldering vapors and possibly upward gas diluted with steam or inert gases the glowing zone of a second Gas generator happened during its downward period. The dust is retained in the process and gasified, the smoldering vapors are cracked and the water vapor largely decomposed.
Da der Staub und der Teer von oben auf das glühende Brennstoffbett des zweiten Gaserzeugers gelangen, tritt die Umsetzung sofort ein, ohne daß Verstopfung o. dgl. durch Staub und Teer auftreten. Das Brennstoffbett wirkt als Filter, zumal bei der genannten Fahrweise die feinste Körnung der Kohle oben liegt und die Korngröße im Brennstoffbett nach unten zunimmt. Die von unten eingeführten gasförmigen Mittel können nötigenfalls vorgewärmt werden, um die Aufwärtsperiode zu verlängern.Because the dust and tar from above on the glowing bed of fuel of the second gas generator arrive, the reaction occurs immediately without constipation o. The like. Occur through dust and tar. The fuel bed acts as a filter, especially since In the above-mentioned mode of operation, the finest grain size of the coal is on top and the grain size increases downwards in the fuel bed. The gaseous agents introduced from below can be preheated if necessary to extend the upward period.
Die Maßnahme, das Aufwärtsgas des einen Gaserzeugers während der Abwärtsperiode in das Kohlenbett eines anderen Gaserzeugers zu schicken, beseitigt teilweise die Nachteile der Verwendung nicht inerter Gase in der Aufwärtsperiode. Die Gaserzeugerfüllung von Wasserdampf am Ende einer jeden Spülperiode geht nicht verloren, sondern wird in der Wassergasreaktion des Nachbargaserzeugers umgesetzt.The measure, the up gas of one gas generator during the down period Sending it to another gas generator's coal bed partially eliminates the Disadvantages of using non-inert gases in the upward period. The gas generator fulfillment of water vapor at the end of each rinse period is not lost, but becomes implemented in the water gas reaction of the neighboring gas generator.
Der Gaserzeuger kann verhältnismäßig niedrig sein, da der aus dem einen Gaserzeuger getragene Staub im anderen Gaserzeuger vergast wird. Das Verfahren kann im Wechselbetrieb von zwei und mehr Gaserzeugern durchgeführt werden.The gas generator can be relatively low because of the dust carried by one gas generator is gasified in the other gas generator. The procedure can be carried out alternately by two or more gas generators.
