Patent ID: 7462333

Claim:
A device for the purification of exhaust gases containing nitrogen and pollutants, particularly those containing fluorocarbon compounds or other fluorine compounds, by thermal-chemical conversion in a cylindrical combustion chamber integrated with a subsequent scrubbing unit and using a burner with central exhaust gas supply and separate supply of fuel gas and oxygen characterized in that the ring burner is provided with drill holes which are arranged on a single hole circle and ensure the locally alternate, simultaneous supply of fuel gas and oxygen, the combustion chamber is closed except for an annular gap between the cylindrical jacket and the end face of the combustion chamber located opposite the burner, that a body, preferably a plate, made of heat-resistant and heat-insulating material is arranged in front of said end face of the combustion chamber, and that a double pipe is arranged concentrically to the cylindrical jacket of the combustion chamber, thus forming an annular channel for the supply of additional oxygen or additional air.
