Atmospheric gas burner made of biosoluble and gel-cast ceramic fibers

A gas burner capable of bringing “artificial fuel” disposed thereon to incandescence, known as a “living-flames” gas burner, for use in a single-heating appliance, comprising a rigid gel-cast ceramic fibers multi-panel element made of 2 or 3 self-supporting boards or panels (1,3 ;

• 1,2,3) and to which a venturi tube supply system (4) is connected for providing primary air and fuel to the burner by gas injection, wherein
• a first upper panel (1) provided with a series of pierced holes and/or slits is disposed on and air-tightly fastened to a second lower panel (3), an intermediate rigid gel-cast ceramic fibers panel (2) being possibly disposed between said first and second panels (1,3) and air-tightly fastened to them, an inner volume (20) used as a mix chamber of primary air to fuel being hollowed out in said second lower panel (3), respectively in said intermediate panel (2), in the two-panel case (1,3), respectively the three-panel case (1,2,3) ;
• a receptacle (5), also made of rigid gel-cast ceramic fibers, is fastened to said lower panel (3) for mating with said venturi tube supply system (4).
