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).

Abstract: A method and an apparatus for thermal decomposition of stable substances, preferably chemical hazardeous waste. The intention is to achieve so high a decomposition temperature that the quantity of remaining chemical traces after the decomposition has been reduced to an absolute minimum. This is achieved by giving the waste the necessary decomposition temperature in a plasma generated in a plasma burner (12). Part of or the whole quantity of the waste is brought into the carrier gas of the plasma. Alternatively part of or the whole quantity of the waste can be supplied to the plasma and mixed with its high temperature carrier gas. The carrier gas of the plasma can be given a temperature of 3000-4000`C or under certain conditions still higher.
