Definitions

  • the present invention relates to a gas burner membrane and a method to provide such.
  • WO9704152 describes a method to provide a gas burner membrane out of metal fibers.
  • sintered metal fiber mats are stiff and therefor are difficult to bend or shape into a burner surface, other than flat. Moreover, during combustion, the sintered mats expand and tend to lift up when they are fixed to the burner housing.
  • textile fabrics comprising metal fibers are provided.
  • a textile fabric refers to a flexible fabric, comprising fibers and being a woven, braided, knitted or nonwoven structure. It does not refer to sintered metal fiber surfaces, which are not flexible. Over its surface, the textile fabric has at least two zones, which have a different air permeability.
  • a gas burner membrane as subject of the invention comprises at least a basic textile fabric layer. Different zones of the textile fabric with different air permeability may be provided to this basic textile fabric layer according to the present invention, in several different ways.
  • a first gas burner membrane as subject of the invention may be provided by adding one or more additional layers of textile fabric on the basic textile fabric layer at certain zones.
  • the various layers of textile fabric are fixed one to another, preferably by spot welding.
  • An alternative gas burner membrane as subject of the invention is provided using different textile structures to provide the different zones of the textile fabric, with different air permeability.
  • textile fabric is a woven textile fabric
  • different textile structures may e.g. be obtained by:
  • Nm metric number
  • Using locally a different weaving pattern e.g. using locally a satin weaving pattern, a rib weaving pattern, a plain weaving pattern, or any other weaving pattern.
  • the number of yarns, the yarn thickness or the knitting structure may be different in specific zones of the fabric. Also, larger or smaller stitches may be provided locally. All this resulting in zones in the textile fabric having a different air permeability.
  • Another alternative gas burner membrane as subject of the invention is provided by using different yarns to provide the textile fabric, said yarns comprising a different quantity of polymer or natural fibers, next to metal fibers.
  • These yarns may be used to provide a fabric as subject of the invention, e.g. by weaving, braiding or knitting.
  • a fabric consisting of metal fibers is left, which comprises various zones. Each zone has different air permeability, dependent on the quantity of metal fibers left in this zone.
  • Yarns having a core consisting of metal fibers, and comprising polymer fibers which cover partially of fully this core may be used.
  • yarns comprising metal fiber may also comprise ceramic fibers or ceramic fiber yarns. It was found that gas burner membranes, comprising metal fibers and ceramic fibers on its burner surface are more resistant to higher temperatures as compared to 100% metal fiber gas burner membranes. “Burner surface” is to be understood as the surface of the gas burner membrane, at which side the combustion takes place. At the same time, they are more resistant to mechanical damage as compared to 100% ceramic fiber gas burner membranes.
  • a metal fiber yarn is first covered partially or fully with ceramic fibers, e.g. by wrap spinning of ceramic fiber yarns around the metal fiber. Polymer or natural fibers may then be added to this combination e.g. by wrap spinning or core spinning techniques.
  • Ceramic fibers may be Al 2 O 3 — based fibers, further comprising SiO 2 .
  • NEXTEL®-fibers are such fibers which may be used.
  • Ceramic fibers based on Al 2 O 3 may be used, e.g. fibers comprising 62% by weight Al 2 O 3 , 24 % by weight SiO 2 and 14% by weight B 2 O 3 .
  • SiO 2 -based fibers are used, such as QUARTZEL® fibers from Quartz & Silice, which comprises more than 99.99% SiO 2 .
  • ceramic fibers are used, next to metal fibers to provide the textile fabric of the gas burner membrane, preferably more ceramic fibers are used to provide the combustion zones with the lowest air permeability.
  • each zone will provide a specific combustion zone to the gas burner membrane.
  • firing load is to be understood as the volume of combustible gas which is provided to a gas burner membrane surface per time unit.
  • the combustion zones having highest air permeability will preferably provide non-radiant combustion, whereas the zones with lower air permeability preferably provide a radiant combustion.
  • the zones, which are closest to the frame in which the gas burner membrane is mounted have low air permeability so providing preferably radiant combustion to improve the combustion stability.
  • a gas burner membrane as subject of the invention thus may comprise various combustion zones, wherein the zones differ in air permeability due to a number of layers of textile, one on top of the other, or to varying textile structure in the textile fabric.
  • Such a gas burner membrane provides the same benefits as a gas burner membrane as described in U.S. Pat. No. 5,439,372, but does not have the disadvantages of the sintered metal fiber surfaces and includes the advantage of having a very flexible and drapable gas burner membrane.
  • the various layers of textile fabric may be provided out of the same textile fabric. So only one textile fabric, with its specific structure is to be manufactured. Various zones, each with its specific shape or design can be provided just buy cutting the surfaces to the various zones out of this fabric and adding them one on top of the other. This provides a very flexible method for designing different gas burner membranes with different zones (as to say custom or tailor made).
  • All type of metal fibers may be used. Fibers obtained by bundle drawing, shaving or cutting action may be used.
  • the equivalent diameter of the metal fibers are usually between 10 and 150 ⁇ m, but preferably between 25 and 50 ⁇ m, e.g. 25 ⁇ m, 30 ⁇ m or 35 ⁇ m.
  • the metal fibers can be different types of stainless steel, nickel alloys and other specific types of steel containing, for example, chromium, aluminum and/or nickel and 0.05 to 0.3% by weight of yttrium, cerium, lanthanum, hafnium or titanium.
  • FIG. 1 shows a knitting structure, which provides a textile fabric to be used as a textile layer.
  • FIG. 2 shows a gas burner membrane as subject of the invention comprising various textile layers over its surface.
  • FIG. 3 show another gas burner membrane as subject of the invention comprising different textile structures over its knitted surface.
  • FIG. 4 shows a gas burner comprising a gas burner membrane as subject of the invention.
  • FIG. 5 show another gas burner membrane as subject of the invention comprising different textile structures over its woven surface.
  • a knitted textile fabric, to be used as a basic textile fabric layer to provide a gas burner membrane as subject of the invention may be provided by knitting sets of yarns 11 , 12 and 13 according to the knitting structure as shown in FIG. 1.
  • the fabrics are provided by knitting on a double bed knitting machine, gauge 5 from H. STOLL GmbH & Co.—Reutlingen (D), knitted on all needles 14 .

  • This ceramic fiber wrapped consolidated metal fiber bundle is than wrapped with polyamid fibers, to provide a yarn which has an outer layer, being substantially provided by this polyamid fibers.
  • the content of such yarn is approximately 63% by weight of metal fiber, 29% by weight of ceramic (Qurtzel®-) fiber and 8% by weight of polyamid fiber.
  • a basic textile fabric layer 21 is used, layer 21 being a knitted fabric as provided by the structure of FIG. 1.
  • Several strips 22 are cut out of an identical knitted fabric, and spot welded to the basic fabric layer. If required, more than one strip may be added one on top of the other.
  • this textile fabric with its different zones 23 , 24 and 25 is used as a gas burner membrane, each of the zones will have its own firing rate. This since the air permeability in zone 23 is different of the air permeability in zone 24 and 25 .
  • Air permeability of 2100 to 2300 I/dm 2* min is measured at zone 24 , comprising only one layer of the knitted fabric, where an air permeability of 1500 I/dm 2 *min is measured at zones 23 , having two layers of textile fabric an air permeability of 1200 I/dm 2 *min is obtained in zones 25 having three layers of textile fabric.
