Abstract

Die Erfindung betrifft ein Verfahren zur Verbesserung der Energiezufuhr beim Aufheizen und Schmelzen eines Schrotthaufwerkes, bei dem durch ein vorgeheiztes oxidierendes Gas unter Zusatz von fossilen Brennstoffen ein Kanal in das Schrotthaufwerk geschmolzen und durch diesen Kanal weitere Energie zugeführt wird. Eine wesentliche Verbesserung dieses Verfahrens wird erreicht, indem die Heißluft zentral von oben auf das Schrotthaufwerk geblasen wird.
