A burner for low-pollutant combustion of a fuel with an oxidising agent is proposed, the end of each fuel feed channel being fitted, according to the invention, with a projection of a section of length L beyond the end of each feed channel for the oxidising agent. In this way, stagewise combustion and aspiration of furnace waste gases for reducing the flame temperature can be accomplished, especially in order to avoid the formation of nitrogen oxides. The emission of pollutants can be further reduced by conical widening of the outside of the end piece of this feed channel. |
