Abstract:
1. A burner having a plenum chamber into which a source of combustible gas may be fed through an inlet thereof, said plenum chamber defining a cavity being a generally planar combustion surface of said burner, said combustion surface being formed firstly of a sheet of metal or other material capable of resisting heat provided with a plurality of apertures therein through which the combustible gas may pass to combust on or proximate the surface of said sheet of metal in the region of said apertures, and secondly of one or more sheets of permeable gauze-like material disposed immediately behind said sheet of metal or other material within the plenum chamber of said burner, said permeable gauze-like material incandescing in the presence of the heat or combustion and characterised in that the apertures within said sheet of metal or other material are arranged in a pattern which both ensures a generally uniform distribution of heat across the combustion surface during operation and which provides a visual display during operation by virtue of the incandescence of the permeable gauze like material viewable through the said apertures, wherein the sheet of metal is provided with a hardening coating which renders said combustion surface substantially black and the incandescence of the permeable gauze-like material being highlighted.
