Definitions

  • NICOLAUS MEURER OF BERLIN-NEUTEMPELHOF, GERMANY, ASSIG-NOR TO METAL- LOGEN GESELLSCHAFT MIT BESCHRANKTER HAFTUNG, OF BERLIN-NEUKOLLN,
  • One of the known nozzle systems consists substantially of three nozzles placed coaxially one within the other, viz, of an inner nozzle for guiding the wire-shaped mate-.
  • the economical working of spraying apparatus is to be increased and, other things being equal, the proportion of oxygen to combustible gas to be considerably reduced or its.
  • the expansion pressure of the atomizing gas (compressed air) emerging in the nozzle system which counteracts the energy of flow of the combustible, gas mixture in the direction towards the nozzle head, must be made less hurtful by the part of the nozzle for conveying the combustible gas mixture having the form of an injector for increasing the velocity of the jetof combustible gas mixture, while the quantity of combustible gas emerging may at the same time be diminished.
  • the combustible gas will be mixed with the oxygen, the amount of which is reduced as compared with what was formerly used, or. with the compressed air used in its place just before the flame is formed, i. e. in the front part of the nozzle head, instead of'as hitherto in the rear part of the nozzle head or even before it.
  • a constructional, form of the nozzle system modified on these lines and shown in longitudinal section in the drawing, has the following features:
  • the inner nozzle (1 for conveying the material to be sprayed is relatively short and is externally conical 'oint therewith.
  • a number of fine holes d are provided, which connect the annular spac'f-between the parts (i and a to the annular space 01
  • the nozzle b is surrounded by a nozzle consisting in the present case of two parts i and j, which is screwed on to a third stepped part e of the nozzle head-e, an annular space 9 being left between the .nozzle b and the surrounding nozzle and-"the part 7', which is rovided with a handle is being capable of being readily withdrawn from the part i by means of the handle.
  • the latter has openings r, which commumcate with ducts (not shown) rovided in the wallof the casing and leadmg to pipe unions (not shown).
  • Theducts and o enings r convey the 'atomizing gas throug holes a into the space 9.
  • Holes t, u, u in the parts 72, e convey the requisite combustible gas to the space 0 and holes o, w, w the requisite oxygen or compressed air to the space
  • the compressed air emerging at a high velocity at 0? through the small openings or the very small quantity of oxygen emerging at d'. carries the combustible gas, which is sucked as by an injector, from the space 0 into the bore- 7'', mixing it at -the same time, and can be ignitedin j.
  • This ignition is facilitated and causes a steady flame to be formed immediately at the point, where the space 0 merges into the bore b, if the nozzle part j be momentarily withdrawn .by the handle from the part c and be returned to itsoriginal position after the flame has been formed.
  • a method of spraying fusible material consisting in feeding the material forward in continuous lengths to a flame produced by the ignition of a combustible gas mixture, fusing the material in the saidv flame and finally atomizing the fused material by directing a jet of compressed gas into it at a point forward of the point of fusion.
  • A. method of spraying fusible material consisting in feedin the material forward in continuous .lengt s to a flame produced by igniting a jet of a combustible gas mixture supplied under pressure and moving at a high velocit fusing the material in the said flame an material by directing a jet of compressed gas into it at a point forward of the point of fusion, the pressure and velocity of the atomizingjet being lower than that of the combustible gas mixture.
  • a method of spraying fusible material consisting in feeding the material forward in continuous lengths to a flame, effecting the mixture of combustion supporting medium and combustible gas necessary for the production of the flame at a point immediately before that at which the flame is formed, fusing the material in the said flame and finally atomizing the fused material by directing a jet of compressed gas into it at a point forward of the point of fusion.
