Abstract

In the process in which, to avoid flame instability and the formation of other pollutants such as CO or soot and also condensate formation and/or fouling phenomena, a waste gas part stream is fed using a waste gas blower via a restrictor flap in a flange between the burner and the burner-mounting plate on the boiler, recycled waste gas passes into a space which is bounded by the flame tube of the burner and a tube which is held by the inserted flange and whose other end bears against the flame tube by a corresponding chamfer, and, in the front region of the flame tube, bores distributed around the circumference are provided, through which the waste gas is distributed into the root of the flame.
