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

Abstract

The present invention is related to 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 multi-panel element made of rigid gel-cast molded ceramic fibers or of bio-soluble ceramic fibers.

1 . 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 ).  
 
     
     
         2 . The gas burner according to  claim 1 , wherein said burner is provided with means for horizontally bringing secondary air to the front and back on the upper panel.  
     
     
         3 . The gas burner according to  claim 2 , wherein said means comprise aligned orifices ( 6 , 7 ) in the upper, lower and possibly intermediate panels ( 1 , 2 , 3 ), each said panel containing at least one of said orifices.  
     
     
         4 . The gas burner according to  claim 1 , wherein the multi-panel element and receptacle are made of ceramic fibers soluble in physiological fluids or of ceramic fibers with low biopersistence.  
     
     
         5 . The gas burner according to  claim 1 , wherein the multi-panel element is covered by a deflector panel ( 80 ) in gel-cast or biosoluble ceramic fibers for a reduction of carbon dioxide content in the flue gases and for oxidation of the flue gases.  
     
     
         6 . The gas burner according to  claim 1 , wherein said artificial fuel comprise artefacts of solid fuel such as wood or coal made of heat-resistant concrete or refractory fibers.
