Device for the purification of exhaust gases consisting of fluorine-containing compounds in a combustion reactor

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