Abstract

In a device for the purification of exhaust gases, especially exhaust gases consisting of fluorine-containing compounds, bore holes (7,8) are made in a ring burner (5) for the separate supply of combustion gas and oxygen on a single hole circle around a central exhaust gas supply (9). The ring burner is arranged in a combustion chamber (1). The combustion chamber is closed up to an annular gap (20) between a cylindrical jacket (4) and a front face (16). Additional oxygen or additional air is introduced into the annular gap (20).
