Process for continuously manufacturing a porous laminate

The invention relates to a burner membrane (1) for radiant burner comprising a porous sintered web of inorganic fibres that are resistant to high temperatures, wherein at least the membrane surface (3) opposite from the fuel supply side (2) has been provided with grooves (4) in the shape of a grid and which grooves bound the meshes (5) of the grid. Preferably, the meshes are regular polygons with a surface area of between 4 and 400 mm.sup.2. The porosity is between 70% and 90% and the permeability variation over its surface is less than 25%.

Burner membrane

A method of compacting a non-woven sintered metal web (1), characterized in that said non woven metal web (1) as such is isostatically pressed, preferably cold isostatically pressed. The isostatically pressed metal web may be used in filter applications and in radiant surface combustion burners.
