Abstract

Bei dem Verfahren wird der flüssige Abfallstoff in einem heißen Rauchgasstrom 4 verdampft und oxidiert. Der Rauchgasstrom 4 enthält dabei den zur Oxidation nötigen Sauerstoff. Wesentlich ist dabei, daß der flüssige Abfallstoff in den heißen Rauchgasstrom 4 mit einer zur Hauptströmungsrichtung senkrechten Komponente als fächerförmiger Flachstrahl mit Hilfe einer oder mehrerer Zweistoffdüsen 6 eingedüst wird, die pulsierend mit einer Frequenz von 5 s-1 bis 70 s-1, vorzugsweise 10 s-1 bis 20 s-1 betrieben werden, wobei an jeder Zweistoffdüse 6 im Wechseltakt ein fächerförmiger Sprühteppich 7 mit relativ groben Tropfen großer Reichweite und ein fächerförmiger Sprühteppich 7 mit relativ feinen Tropfen kleiner Reichweite erzeugt wird, so daß der Rauchgasstrom 4 alternierend mit feinversprühter kurzer Reichweite und groben, das Rauchgas mit relativ großer Wurfweite durchdringenden Tropfen beaufschlagt wird.

In the process, the liquid waste material is evaporated and oxidized in a hot flue gas stream 4. The flue gas stream 4 contains the oxygen necessary for the oxidation. It is essential that the liquid waste material is injected into the hot flue gas stream 4 with a component perpendicular to the main flow direction as a fan-shaped flat jet with the help of one or more two-substance nozzles 6, which pulsate at a frequency of 5 s -1 to 70 s -1 , preferably 10 s -1 to 20 s -1 are operated, a fan-shaped spray carpet 7 with relatively coarse drops having a long range and a fan-shaped spray carpet 7 having relatively fine drops having a small range being generated in alternation at each two-component nozzle 6, so that the flue gas stream 4 alternates with finely sprayed short range and coarse, the flue gas with a relatively large throw penetrating drops.
