Abstract

A method and an apparatus for the production of a melt (42) from minerals and/or raw materials preferably for mineral wool. The method is performed in a process furnace (10, 26) that at a first place is equipped with an adjustable feed opening (24) for the lumped raw material (18) and at a second place (26) with an inlet opening for a process gas that is heated by a plasma in a plasma generator (32) to a high temperature. A mixing chamber (38) is arranged to receive the process gas before it is let into the furnace. To the mixing chamber (38) a number of feed devices (45, 46, 48) are conducted and through which a fine particle fraction of the material, solid fuel resp. waste material can be introduced into the mixing chamber. Further there is a recirculation pipe (50) for the recovery of process exhaust gases from the upper part of the process furnace (16) to the plasma generator (32).
