Abstract

Sulfur-free combustion gases of low soot content are produced by mixing oxygen and an off-gas of a defined composition in a defined weight ratio, passing the final mixture thus obtained through a defined number of slit channels of gas burners into a combustion chamber and combusting it at a defined temperature. Compared to the prior art, the process of the invention gives sulfur-free combustion gases, containing little or no soot (in general containing no detectable soot), more simply and more economically. These gases are used for heating, in particular for raising steam.
