Abstract:
1. A method for the regeneration of residues containing sulfur in that a droplet stream containing the residue is introduced into a reactor and fed to a reaction zone consisting of hot flue gases that are generated through the combustion of a fuel, and heated in said reaction zone so that compounds of the residues containing sulfur are thermally cleaved, characterized in that a droplet stream containing fuel is introduced into the reactor simultaneously with the droplet stream containing the residue, and is fed into a pre-reaction zone that is created by feeding in an oxygen-rich gas stream, whereby the residue in the pre-reaction zone is partially thermally cleaved and subsequently fed into the reaction zones, wherein the residue is atomized using an atomizing burner having a central inner nozzle that feeds in the residue-fuel mixture and that is coaxially surrounded by an inert gas nozzle and by a ring-shaped nozzle that feeds the oxygen-rich gas stream as an oxygen-rich sheathing gas stream, whereby inert gas is fed through the inert gas nozzle.
