Abstract

Die Erfindung betrifft ein Verfahren zur thermischen Verwertung von Schredder-Leichtfraktion mit einem Korngrößenanteil größer 2 mm von zumindest 50 %, wobei die Schredder-Leichtfraktion mit einem sauerstoffhältigen Gas, welches gegenüber Luft unter Normalbedingungen in seiner chemischen Reaktivität erhöht ist, in einem Schmelzzyklon zur Zündung gebracht und geschmolzen wird.The invention relates to a process for the thermal utilization of shredder light fraction with a grain size fraction greater than 2 mm of at least 50%, the shredder light fraction with an oxygen-containing gas, which is chemically more reactive to air under normal conditions, in a melting cyclone for ignition brought and melted.
