Abstract
The present invention describes a process for the disposal of residual substances from waste incineration plants as well as activated coke and/or activated carbon. For this purpose the residual substance as well as activated coke and/or activated carbon is introduced into the annular shaft (3) of the primary chamber (2) of the furnace (1). In the primary chamber (2) a temperature of 1250.degree. C. to 1500.degree. C. is set. The molten material flowing off leaves the primary chamber (2) together with the flue gases through the central outlet (4). The molten material is passed through the secondary chamber (5) and is discharged as slag. The present invention furthermore describes an apparatus for such process, where in the furnace roof (10) of the primary chamber (2) of the furnace (1) one or several burners (7) are disposed and at one or several points (22) of the furnace roof (10) secondary air is introduced into the primary chamber (2) and at one or several points (23) of the furnace roof (10) tertiary air is introduced into the primary chamber (2).
