ABSTRACT:
The invention relates to a method and plant for converting waste material containing and/or comprising thermally disintegratable chemical substances to stable final products such as CO.sub.2, H.sub.2 O and HCl, the waste material being subjected to a plasma gas of high temperature generated in a plasma generator in order to effect disintegration.
The waste material in feedable form is caused to flow through a reaction zone, heated by a plasma gas to at least 2000.degree. C. The reaction zone comprises a cavity burned in a gas-permeable filling in piece form arranged in a reaction chamber, by means of the plasma jet from the plasma generator directed towards and projecting into said filling. An appropriate oxygen potential is maintained in at least the reaction zone such that the disintegration products are continuously converted to stable final products.
