Abstract

A burner having feed ducts for homogeneous or heterogeneous reactants and a burner cooling chamber placed peripherally in the area of a burner head, the burner including, coolant feed and discharge ducts in communication with the burner cooling chamber, a burner lance positionable in a recess in the burner cooling chamber, and a lance for accommodating the feed of the reactants as far as the burner orifice wherein the burner cooling chamber extends over the burner orifice in a downstream direction, starting from a downstream side of the burner orifice, and tapers conically to a smaller cross section so as to form a truncated conical burner prechamber, open on a downstream side thereof.
