<p>A burner assembly in which an annular passage is provided for transporting an fuel/air mixture to a furnace inlet. A conical divider member is disposed within the annular passage for dividing the stream of fuel/air passing through the passage into two radially-spaced coaxial, passages. A plurality of angularly-spaced walls are disposed within one of said passages for dividing the latter passage into a plurality of segments for splitting up fuel/air stream so that, upon ignition of said fuel, a plurality of flame patterns are formed. Ribs are provided on one of the surfaces defining the other passage to concentrate the fuel portion of the mixture flowing through said latter passage to form an additional flame pattern which is surrounded by the above-mentioned plurality of flame patterns. <IMAGE></p> |
