Abstract

Verfahren zur Inertisierung von Flugasche aus Verbrennungsanlagen mit mindestens einem Brennraum. Die Aufgabe liegt darin, ein wirtschaftliches Verfahren vorzuschlagen. Die Aufgabe wird durch ein Verfahren, umfassend ein Abscheiden von Flugasche in einem Staubabscheider und einer Behandlung der Flugasche mit einem gasförmigen Reduktionsmittel im Temperaturbereich zwischen 600 bis 700 °C, wobei selektiv Metallsulfate in ihre metallische Form oder Sulfide überführt werden.
