    摘要: A method for manufacturing a porous laminate includes continuously passing a laminate preform having a metal wire mesh and a metal non-woven fiber web superposed on the wire mesh between rotating pressure rollers having differing electrical potentials. The fibers of the non-woven web are sintered together at mutual points of contact and to the mesh by passing an electrical current cross-sectionally through the laminate preform in a zone of contact with the rollers, thereby forming the porous laminate.

    摘要: 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%.
