Methods for the thermal treatment of a material

Abstract

The invention relates to a method for the thermal treatment of a substance (2) in a furnace, wherein the substance (2) is heated by the combustion of a fuel gas (16) and / or by means of a plasma which is provided in or by a plasma generating element (9) from a plasma gas (12), and / or by means of a hot gas produced with the plasma, wherein at least a part of the fuel gas (16) and / or an oxygen source (18) is used as the plasma gas (12), wherein the plasma gas (12) is supplied to a device (6) for providing thermal energy by inductive generation of the plasma.
