In order to improve an enveloping gas device (20) for transporting at least one enveloping gas (H) that is allocated to at least one burner head or at least one nozzle (10) of a device (100) for working or processing at least one component or workpiece (B) by autogenous processes, so that a reduction of the contaminant concentration, particularly the concentration of nitrogen oxides (NOx) and other harmful compounds is achieved, it is suggested, a flame (F) issuing from the burner head or nozzle (10) and directed towards the component or workpiece (B) is enclosed by the enveloping gas (H), and the concentration of contaminants contained in the waste gas from the device (100), particularly the concentration of nitrogen oxides (NOx), is reduced by the enveloping gas. The present invention further relates to a corresponding method associated with the enveloping gas device (20) for working or processing at least one component or workpiece (B) with autogenous processes.
