  • Attenuation of the primary filaments l2 to ne short fibers is accomplished by means of a burner l5 or name blower which is capable of producing an intensely hot gaseous blast of Very high velocity.
  • the ends of the filaments are projected into the flame by the feed rolls and are substantially instantaneously melted so that the molten tips of the laments are attenuated into extremely line bers by the force of the flame or blast.
  • These bers when gathered together by suitable collecting means (not shown), form a mass having a cottony or wool-like texture which may be formed into mats, bats, or rovings, or slivers from which yarns or threads may be twisted, by any conventional process.
  • the combustion chamber burner of the present invention provides a substantial increase in both temperature and flame velocity so that increased production is realized as will be brought out in detail presently.
  • the burner l5 as illustrated in Figure 3 of the drawings comprises a shell or casing I8 preferably formed of metal and preferably of rectangular shape, and adapted to support the burner structure therein.
  • the shell is provided in one end with a slot I9 through which the burner structure dening the burner orifice projects and is open at its other end.
  • Flanges 2l] at the upper and lower edges of the open end of the shell provide means by which a cup-shaped closure cap 2
  • a pipe connection 23 is provided in the cap 2l to supply a highly combustible fuel through a pipe 24 to the burner from a suitable source.
  • Such a fuel may be a premixed fuel gas and air
  • suitable fuel gases including ordinary manufactured or natural fuel gas, methane, propane, or other readily combustible gases.
  • the gas-air mixture is supplied to the burner at a pressure less than l0 pounds per square inch and preferably at pressures of from 1 to 3 pounds per square inch.
  • the fuel gas-air mixture has the advantage of being readily obtainable and is more easily and safely handled than, for instance, propane or other highly compressed gases. Also, it is more economical than oxygen-acetylene when burned in sufficient volume to produce a blast having the high velocity obtainable with the gas-air mixture.
  • the burner includes within the shell I8 an elongated combustion chamber 25 divided by a partition wall 26 or baille to form in effect a pair of chambers 21 and 28 or compartments communicating with a common narrow rectangular dischargeorice 3B through which the products of combustion escape.
  • the partition wall 26 may be formed integral with the chamber or it may be supported when formed separately in grooves 26a provided in the side walls of the burner chamber.
  • the walls forming the chambers 21 and 28 may be formed of a suitable ceramic refractory material capable of withstanding high temperatures. The life of the refractory material is extended if a liner 32 of high melting point metal is employed to cover the refractory wall as illustrated herein although the use of the liner is not necessary.
  • the refractory materials from which the body of the burner may be formed are, for example, the metal oxides or carbides such as tungsten carbide, boron carbide,
  • the entire burner body may be formed of one or a suitable combination of some of the above materials.
  • the metallic liner 32 may be formed in any suitable way, for instance, by the powder metallurgy method of pressing nely divided metal to the proper form and then sintering the particles to consolidate them intoV an article of the desired shape.
  • Tungsten and tungsten alloys are examples of high melting point metals suitable for this method of production and are adapted to withstand the temperatures approaching 4000n F.
  • the metal liner may be used alone to form the chamber but since it is most economically formed rela.. tively thin it is preferable to reinforce the liner by a backing of ceramic refractory material as shown at 33, the refractory material acting also to insulate the liner from the shell I8.
  • Complementary orifice plates 35 mountedvwithin the cap 2l are adapted to register with the chambers 21 and 28 and provide a uniformly distributed llow of fuel to the combustion chambers.
  • the plates are preferably formed of a ceramic material and are held in place against the liner and wall members by the cap bolts 22.
  • the present burner overcomes this objection to previous burners mainly by having the orifice 30 offset with respect to each chamber so that incompletely burned gas does not pass directly from the orilce plate 35 to the discharge orifice 3U. Also, higher temperatures are developed within the present burner and cause combustion rea-ction to take place more rapidly and completely.

  • the side walls of the chambers are vertical and substantially parallel while the upper and lower walls ( Figure 3) curve or taper toward each other in the direction of the orifice.
  • the partition wall 26 is provided with a tapering forward edge and forms with the top and bottom walls substantially restricted passages through which the gas passes before reaching the orifice. This increases the Velocity of the products of combustion from each chamber before the two streams of gas are combined.
  • the complementary converging outer walls of the passages tend to direct the ames at a substantial angle toward each other which results in the increased turbulence previously mentioned.
