Abstract

In a process for melting inorganic materials (7) in a rotary horizontal converter or a rotary kiln (1) by adding fuel (8), oxygen or oxygen-enriched gases (10) and the inorganic materials (7) to a liquid bath (5), solid fuel (8) is added in piece form. The oxygen or the oxygen-enriched gas (10) is blown at high velocity (v) onto the surface of the bath (5), reacts with the solid fuel (8) and releases heat in the course of this. By means of the process of the invention, high temperatures can be achieved with the use of inexpensive fuels.
