摘要： Paper mill sludge or similiar organic sludges with a high ash content are converted by burning the sludge in a cyclone furnace (10) along with another source of fuel. The heat content of the sludge is recovered and the ash content of the sludge is converted to a glassy slag. A flux, such as limestone, may be added to the sludge before introduction into the cyclone furnace (10). The slag is useful as a construction material, an abrasive, for roofing products, or for other purposes.

摘要： Bei einem Verfahren zur thermischen Umsetzung von brennbaren, energieenthaltenden Reststoffen mit verschiedenen Korngrößen bei Temperaturen oberhalb des Schmelzpunktes von mineralischen Bestandteilen der Reststoffe zur Gewinnung von Feststoffen und Abgasen durch Umsetzung von Reststoffen mit Sauerstoff und/oder Luft bei Normaldruck werden die Reststoffe in einem oberen Bereich eines Hochtemperaturreaktors zusammen mit einem Luft- bzw. Sauerstoffstrom über eine Zufuhreinrichtung zugeführt und zur Reaktion gebracht werden. Die Reststoffe werden in dem Hochtemperaturreaktor zu flüssiger Schlacke und Gas umgesetzt. Die flüssige Schlacke wird in einem im unteren Bereich des Hochtemperaturreaktors sich befindlichen Schmelzbad gestaut. Der Feinkornanteil der Reststoffe wird zu Schlacke und Gas im wesentlichen in einem stehend angeordneten Freiraum des Hochtemperaturreaktors umgesetzt. Der Grobkornanteil der Reststoffe wird im wesentlichen im und auf dem Schmelzbad zu Schlacke und Gas umgesetzt. Die erzeugte flüssige Schlacke fließt unterhalb eines Stauelements durch und wird oberhalb eines Überlaufelements gemeinsam mit dem erzeugten Gas über eine Abflußöffnung des Hochtemperaturreaktors aus demselben abgeführt.
