An improved combustion element (1) for a radiant energy burner. The element comprises a generally cylindrical metal screen (4) having its outer end closed off by an end closure (5), while the inner end is connected to a source of gaseous fuel. Strands of ceramic material are braided directly on the outer surface of the screen to form a braided sleeve (6) which snugly fitted over the entire periphery of the screen. An inner end of the screen has a circumferential groove (9), where the sleeve is provided with an inner double-backed section (8), the sleeve passing into the groove to provide a mechanical interlock between the inner end of the sleeve and the screen. |
