Description

Verfahren zum Herstellen von Wassergas. In dem Hauptpatent ist ein Verfahren zum Herstellen von Wassergas aus körnigen Kohlen beschrieben, bei welchem Luft wie Wasserdampf derart durch die Kohle geblasen werden, daß diese sowohl während des Heißblasens wie während des Wassergasblasens sich dauernd in wirbelnderBewegung befindet. Die bei dem Blasen sich bildende Asche wird hierbei zum Teil von dem Luftgas und zum Teil von dem Wassergas mit fortgeführt, so daß auch das letztere vielfach stark staubhaltig ist.Method for producing water gas. In the main patent is a Process for producing water gas from granular coals described in which Air as well as water vapor are blown through the coal in such a way that these both during during hot blowing, as during water gas blowing, are constantly in a whirling motion is located. The ash that forms during the blowing is partly relieved by the air gas and partly carried along by the water gas, so that the latter also in many cases is very dusty.

Es wurde nun gefunden, daß man ein staubarmes Wassergas dadurch erhält, daß man die Kohlen zwar beim Heißblasen mittels des Luftstromes aufwirbelt, den Wasserdampf aber derart durch die Kohle bläst, daß diese nicht in Bewegung gerät. Da nun die glühende Kohle schon mit sehr geringen von unten eingeblasenen Dampfmengen in Wirbelung gerät, so ist es zweckmäßig, den Dampf von oben nach unten durch die Kohle zu schicken. Die Kohle kann dann auch beim Durchschicken sehr großer Dampfmengen nicht in Bewegung geraten, und die sich bildende Asche kann von den Kohlenteilchen nicht abgerieben werden, so daß sich ein weitgehend staubfreies Wassergas ergibt. Läßt man dieses unmittelbar am Generator aus einer größeren öffnung ausströmen, z. B. 3 cbm in einer Minute, und entzündet es, so verbrennt es mit fast farbloser Flamme, während sonst die Flamme intensiv gelb gefärbt ist und das nichtbrennende Gas, schon dem bloßen Auge sichtbar, Staubteilchen erkennen läßt. Die Zusammensetzung des Wassergases ist die gleiche wie in dem Hauptpatent angegeben.It has now been found that a low-dust water gas is obtained by that although the coals are whirled up by means of the air flow during hot blowing, the But water vapor blows through the coal in such a way that it does not start moving. Now the glowing coal is already with very small amounts of steam blown in from below gets into a vortex, it is useful to pass the steam from top to bottom through the To send coal. The coal can then also be used when sending very large amounts of steam Do not move, and the ash that forms can be removed from the coal particles are not rubbed off, so that a largely dust-free water gas results. If this is allowed to flow out of a larger opening directly on the generator, z. B. 3 cbm in a minute, and ignite it, it burns with almost colorless Flame, while otherwise the flame is colored intensely yellow and the non-burning one Gas, even visible to the naked eye, allows dust particles to be recognized. The composition of the water gas is the same as stated in the main patent.

Sowohl das Verfahren im Hauptpatent als auch das vorliegende läßt sich wirtschaftlicher gestalten, wenn man die fühlbare Wärme des beim Heißblasen der Kohle entstehenden kohleno:cydreichen Gases ausnutzt, z. B. zur Vortrocknung des Brennstoffs oder bzw. und zur Erhitzung von Cowpertürrnen, in denen man es gegebenenfalls verbrennt, worauf dann beim Wassergasblasen der Dampf erst durch die in Hellrotglut befindlichen Türme und von da aus in den Generator geleitet wird. Man erhält so stark überhitzten Dampf und die Periode des Wassergasblasens wird bedeutend verlängert.Both the method in the main patent and the present one can not Make yourself more economical if you can feel the warmth of hot blowing the coal resulting from the coal: exploits cyd-rich gas, z. B. for pre-drying of the fuel or or and for heating cowperturrnen, in which it can be used if necessary burns, whereupon when the water gas bubbles the steam only through the bright red glow located towers and from there into the generator. You get so strongly superheated steam and the period of water gas blowing is significantly lengthened.
