Verfahren zur Hochtemperaturvergasung heterogener Abfälle

摘要

Described is a method for the high-temperature gasification of optionally thermally pretreated heterogeneous waste, the method calling for oxygen to the supplied to the gasification bed by means of water-cooled oxygen lances. The oxygen is heated by an independent pilot flame and accelerated to supersonic speed. Since the pilot flame is operated permanently and independently of the flow of oxygen through the lance, the oxygen lance cannot be closed off by fused, non-gasificable components of the waste. This pulsating phase-staggered action of several concentrically disposed oxygen lances gives a circulating flow of material in the gasification zone which compensates for the heterogeneous nature of the waste.
