Abstract

Die Erfindung betrifft ein Verfahren zum Einbinden von Filterstäuben in eine Schlacke bei dem in einer Brennkammer Abfallstoffe einer thermischen Behandlung unterzogen werden, wobei die Schlacke gebildet und Rauchgase freigesetzt werden und aus den Rauchgasen die Filterstäube abgetrennt und in die Brennkammer zurückgeführt werden.The invention relates to a method for incorporating filter dusts into a slag in which waste materials in a combustion chamber are subjected to a thermal treatment, wherein the slag is formed and flue gases are released and released the filter dusts are separated from the flue gases and into the combustion chamber to be led back.

Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren der eingangs genannten Art vorzuschlagen, bei dem die Filterstäube zu einem erheblich höheren Ausmaß in die Schlacke eingebunden werden.The invention has for its object a method of propose the type mentioned, in which the filter dust incorporated into the slag to a significantly greater extent become.

Die Lösung der Aufgabe ist dadurch gekennzeichnet, daß die Filterstäube zu Preßlingen geformt werden, deren Dichte mindestens der Dichte der Schlacke entspricht, und daß die Preßlinge in die Brennkammer zurückgeführt werden.The solution to the problem is characterized in that the Filter dusts are formed into compacts, the density of which is at least corresponds to the density of the slag, and that the compacts be returned to the combustion chamber.
