1. Burner membrane comprising at least two metal woven fabric layers consisting only of stainless steel and present one of top of the other,wherein the at least two metal woven fiber layers are sintered to one another,wherein the burner membrane has an entry side for a fuel/air mixture and has a combustion side, the entry side facing away from the combustion side,wherein the combustion side is an exit side, is configured so that combustion takes place directly on the combustion side, is configured to take part in flame ignition and stabilization of a flame, and is configured to face a combustion chamber,wherein the burner membrane has additional openings for passage of additional fuel/air mixture,wherein each respective orifice of the additional openings has an irregular configuration projecting beyond the exit side of the burner membrane,wherein the additional openings are configured as passage holes that connect the entry side and the exit side of the burner membrane,wherein each orifice is configured to hold a respective flame root of a higher separate flame, andwherein the irregular configuration of the orifices takes place via a fiber material displacement by producing the additional openings and comprises frayings of an edge of the orifices. 2. Method for complete combustion of a homogeneous mixture of air and fuel, via a woven fabric membrane composed of inorganic precious metal fibers disposed upstream from a combustion side and downstream from a device that serves for feed of the fuel/air mixture, and is permeable for the mixture,having an entry side of the woven fabric membrane for the fuel/air mixture on the membrane side facing away from the combustion side of the membrane,having an exit side of the membrane, facing away from the entry side of the latter, forming the combustion side, on which combustion takes place directly, and which takes part in flame ignition and stabilization thereof,with generation of a planar or curved low flame field via the fuel/air mixture on the exit side of the woven fabric of the membrane, andhaving additional openings in the membrane for additional fuel/air mixture passage and for generation of a flame field having higher separate flames having separate flame roots,wherein the flame roots of the higher flames are kept cool in that the orifices of the additional openings of the membrane have an irregular special configuration,wherein the orifices furthermore project beyond the exit side of the woven fabric, for achievement of cooling of the flame root of the higher flames,wherein the additional openings are configured as passage holes that connect the two sides of the membrane, whose orifices, forming the flame root, project out of the openings, in each instance, on the exit side of the woven fabric into the combustion chamber, forming their orifices, andwherein the orifice configuration occurs by modification of the woven fabric in the form of fraying of the orifice edge. 3. Method according to claim 2, wherein the flow of the fuel/air mixture for generation of the planar low flame field is achieved on the basis of the porosity of the fiber fabric, and wherein the additional openings for generation of a separate flame field with flames having cool flame roots occur, not only in flat membranes but also in domed or tubular membranes. 4. Method according to claim 2, wherein because of the cooling of the flame root, the NOx component in the waste gas is greatly reduced, all the way down to a theoretical minimal value. 5. Method according to claim 2, wherein as a result of the cold flame root, the combustion power stress on the membrane exit side that can be achieved can be more than doubled as compared with known burners, and can be adapted to the power demand. 6. Method according to claim 2, wherein because of the configuration of the orifices of the additional openings, resonance vibrations are immediately reduced when they occur, or cannot occur in the first place. 7. Method according to claim 2, wherein for configuration of the orifices of the additional openings, disposed essentially perpendicular to the surface of the membrane, this configuration takes place via displacement of woven fabric of the membrane.
