Description

Schwelverfahren. Bei der Schwelung fester Brennstoffe mit Innenheizung ist es üblich, die fühlbare Wärme des festen Rückstandes dadurch für den Prozeß nutzbar zu machen, daß man den Gasstrom im Kreislauf durch die Kühlzone und dann durch die Schwelzone führt. Wenn man in solchen Fällen Zusatzgas zur Erwärmung auf die Schweltemperatur verwendet, wird dieses dem vorerwähnten Gasstrom zwischen der Kühlzone und der Schwelzone beigemischt.Smoldering process. When smoldering solid fuels with internal heating it is common to use the sensible heat of the solid residue for the process to make usable that one circulates the gas stream through the cooling zone and then leads through the smoldering zone. If you use additional gas for heating in such cases the smoldering temperature is used, this is the aforementioned gas flow between the Added to the cooling zone and the smoldering zone.

Die Erfindung besteht darin, daß die Kühlung des Schwelrückstandes nicht durch den kreisenden Schwelgasstrom erfolgt, sondern durch das Zusatzgas.The invention consists in that the cooling of the smoldering residue takes place not by the circulating carbonization gas flow, but by the additional gas.

Gegenüber den früheren Verfahren bietet die vorliegende Erfindung verschiedene Vorteile.The present invention provides over the previous methods various advantages.

Ein Vorteil besteht darin, daß man bei dem neuen Verfahren sehr wasserdampfreiches Zusatzgas verwenden kann, da das Zusatzgas nicht verbrannt wird. Der 'hohe Wasserdampfgehalt wirkt aber wiederum für die Schwelung sehr günstig, da sowohl die Menge als auch die Güte des Teeres gesteigert wird.One advantage is that the new process is very rich in steam Can use make-up gas because the make-up gas is not burned. The 'high water vapor content but again has a very beneficial effect on the smoldering, as both the amount and the quality of the tar is increased.

Ein anderer Vorteil besteht darin, daß man bei dieser Arbeitsweise das gereinigte und bei dieser Gelegenheit vom Wasserdampf befreite Schwelgas für die Aufheizung verwenden kann. Dieses fast wasserdampffreie Gas ermöglicht eine ungestörte und sichere Verbrennung.Another advantage is that you can work in this way the cleaned and, on this occasion, freed from the steam for carbonisation gas can use the heating. This gas, which is almost free of water vapor, enables a undisturbed and safe combustion.

Ein dritter Vorteil ist noch der, daß man für die Erzeugung des Zusatzgases wasserreiche, billige Brennstoffe verwenden kann, ohne eine Kondensation durchführen zu müssen.A third advantage is that you have to generate the additional gas can use water-rich, cheap fuels without condensation to have to.

PATENTANSPRUCH: Verfahren zum Schwelen von Brennstoffen mittels eines kreisenden Stromes heißer Schwelgase, denen ein Fremdgas beigemischt wird, dadurch gekennzeichnet, daß der Schwelgasstrom nur in der Schwelzone kreist und das Zusatzgas vor seiner Mischung mit dem Schwelgas durch die Kühlzone geführt wird. Claim: method for smoldering fuels by means of a circulating stream of hot smoldering gases to which a foreign gas is added, characterized in that the smoldering gas flow circulates only in the smoldering zone and the additional gas is passed through the cooling zone before it is mixed with the smoldering gas.
