ABSTRACT:
The aim of the invention is to produce a spray burner, starting from a conventional spray burner, for the atomisation and combustion of sulphur-containing residues, comprising a residue nozzle, for the introduction of sulphur-containing residue, which is surrounded by an outer nozzle, for the introduction of an atomising agent, whereby said burner is suitable for a method in which oxygen can be introduced in the cracking oven as additional oxidising agent to increase the capacity and improve the economic efficiency without the above disadvantages and limitations and is also optimised for a variable throughput of residue for atomising. Said aim is achieved whereby the residue nozzle comprises a multiplicity of individual nozzles which may be switched on and off, connected to an input for the residue, an inlet for fuel is provided and the outer nozzle is connected to an inlet for an oxygen-enriched gas stream.
