Porous fuel treatment element

Abstract

The invention relates to a porous fuel treatment element for an evaporation burner, comprising at least one layer ( 8 ) formed by fibers ( 10 ). Said fibers ( 10 ) comprise basalt fibers.

1 . A porous fuel treatment element for an evaporation burner, having:
 at least one tier that is formed from fibers,   wherein the fibers comprise basalt fibers.   
     
     
         2 . The porous fuel treatment element as claimed in  claim 1 , wherein the at least one tier has a textile planar structure. 
     
     
         3 . The porous fuel treatment element as claimed in  claim 2 , wherein the textile planar structure is a felt, a non-woven fabric, a needled mat, a scrim, a woven fabric, a warp/weft-knitted fabric, a knitted fabric, or a braided fabric. 
     
     
         4 . The porous fuel treatment element as claimed in  claim 1  wherein the fibers of the textile planar structure have a diameter distribution in the range between 5 μm and 35 μm. 
     
     
         5 . The porous fuel treatment element as claimed in  claim 1 , wherein the fibers have a length of at least 150 μm. 
     
     
         6 . The porous fuel treatment element as claimed in  claim 1 , wherein the porous fuel treatment element has at least one tier comprised of basalt wool. 
     
     
         7 . The porous fuel treatment element as claimed in  claim 1 , having at least one further tier formed from fibers. 
     
     
         8 . The porous fuel treatment element as claimed in  claim 7 , wherein the fibers of the at least one further tier also comprise basalt fibers. 
     
     
         9 . The porous fuel treatment element as claimed in  claim 1 , wherein the fibers have a glass-type amorphous structure. 
     
     
         10 . The porous fuel treatment element as claimed in  claim 1 , wherein the fibers of the at least one tier are interconnected by sintering. 
     
     
         11 . The porous fuel treatment element as claimed in  claim 1 , wherein the fibers are formed by fiber bundles, multifilaments, or rovings. 
     
     
         12 . An evaporation burner for a mobile heating apparatus operated by liquid fuel, having a porous fuel treatment element as claimed in  claim 1 . 
     
     
         13 . A heating apparatus having an evaporation burner which has a porous fuel treatment element as claimed in  claim 1 . 
     
     
         14 . The porous fuel treatment element as claimed in  claim 1 , wherein the fibers have a length of at least 200 μm.
