Abstract

The invention relates to a burner for combustion, which is low in pollutants, of a fuel (natural gas) with an oxidation gas. As a result of the oblong, in particular wedge-shaped design according to the invention of the outlet openings of the admission ducts for the oxidation gas, an NOx reduction is achieved as a result of increased waste gas recirculation and stepwise combustion.
