Abstract

The invention describes a tubular burner consisting of a cylindrical tubular body initially open at either end into which a distributor component can be slidingly fitted. The tubular body is provided with rows of apertures over a narrow area of the uppermost surface thereof to give the burner a flame strip. The distributor is substantially the same axial length as the tubular burner body but of smaller cross-sectional dimension than said body allowing for sliding fitment of the distributor inside the burner body. In accordance with the invention, the distributor has a first tubular portion and a second extension portion which is effectively a continuation of the upper surface of said first tubular portion, and both the tubular portion and extension portion of the distributor are provided with axially aligned flanges on either aide having a number of perforations. As the distributor is slid axially along the tubular burner body, the edges of the flanges engage with the inner walls of the tubular burner body and thus divide the burner body into an upper and lower chamber, the combustible air/gas mixture emerging from the tubular portion of the distributor into the lower chamber and subsequently being urged upwardly through the apertures in said flanges into the upper chamber before passing through the flame ports for combustion on the upper surface of said tubular body. The invention also relates to a distributor for use in such a burner.
