Abstract

Surfaces are sooted by means of a burner, which burns a carbon-containing fuel gas with air or oxygen. If a sooting step is to be repeated at relatively short intervals, the sooting flame burns continuously. This means unnecessary production of soot which pollutes the environment, and ultimately an undesired sooting of parts and devices. These disadvantages are eliminated if the fuel gas/air or fuel gas/oxygen mixing ratio is reduced in those phases in which sooting is not intended to take place, and a soot-free small flame is thus produced.
