Removal of noxious substances from gas streams

摘要

A process for the combustive destruction of noxious substances from a gas stream in which the gas stream and added fuel gas as a mixture into a combustion zone that is surrounded by an exit surface of a foraminous gas burner. A fuel gas and air/oxygen mixture are simultaneously supplied to the foraminous gas burner to effect combustion at the exit surface. The resulting combustion product stream is discharged from the combustion zone. The oxygen is added to the gas stream and the fuel gas prior to the introduction of the mixture to the combustion zone and the oxygen/fuel gas mixture burns at the point of injection.
