Definitions

  • the partial burners may be individually orientatable if desired to achieve a further versatility.
  • the present invention relates to multiple fuel burners.
  • the method is well known currently of carrying out various metallurgical and siderurgical operations by means of burners of a type known as oxy-fuel burners, in which the supporter of combustion used is pure oxygen, supplied in amounts suitable for the operation envisaged.
  • oxy-fuel burner means a post mixing burner in which the liquid fuel is mixed with and atomised by oxygen jets outside the body of the burner.
  • the aim of the present invention is an improvement in the said arrangement, by which it is possible to obtain a further increase in the effective surface area covered by burners of this type.
  • the improvement provided by the invention has the considerable advantage of making it possible to keep the burner in a fixed, or practically fixed, position, which means that the whole device for the periodic operation itself of the burner can be eliminated, together with all the inconvenience inherent in operating, maintaining and contigently repairing the said device.
  • the improvement of the invention consists essentially in uniting in a single burner body at least two partialburners of the oxy-fuel-gas type, which can, be supplied with gas independently of each other, the flame of each partial-burner preferably being adapted to be directed in a different direction.
  • the invention accordingly consists in a multiple fuel burner, comprising a body having at its end on the outlet side an obturating plate, the said plate having at least two groups of nozzles, each group comprising nozzles K 3,476,321 Patented Nov. 4, 1969 "ice supplied respectively with pure oxygen, gaseous fuel, liquid fuel, according to an arrangement known per se, each of the said groups accordingly forming the head of an oxy-fuel-gas partial-burner; the nozzles of each group being connected to channels having supply members suitable for each groupandv independent of those of the other groups.
  • Each partial-burner can have a separate liquid cooling device, or the body of the burner can have a single cooling device serving both or all the partial-burners.
  • the single body of the burner serves in actual practice as a sheath for the partial-burners, which latter can arranged on its periphery, inclined in the direction of also have an individual cooling circuit.
  • Each partial-burner head can moreover have nozzles the flame axis. By supplying the said nozzles individually with fuel and oxygen, it is possible to alter the shape of the flame of each partial-burner entirely independently.
  • FIGURES la, 1b, and 1c are three views of one form of the burner of the invention.
  • FIGURES 2a, 2b, and 20 show alternative arrangements which can be adopted for the faces of three partialburners.
  • FIGURES 3a, 3b and 3c show a further alternative arrangement
  • FIGURES 4a and 4b show a still further alternative arrangement
  • FIGURES 5 and 6 are two views which show a method of producing a multiple burner in which the partialburners are themselves orientable.
  • the burner of FIGURES 1a, 1b and 1c shown in side and front elevation and in plan, is constituted of three partial-burners (1, 2, 3) of oxy-fuel-gas in juxtaposition, the three flames being in the same plane.
  • Each of the said partial-burners has its obturating plate with nozzles and each has its own supply conduits for oxygen, liquidfuel an gaseous fuel as well as compressed air.
  • FIGURES 2a, 2b and 2c show a modification of the relative arrangements of the three burners from the horizontal arrangement of burners. The views are similar to those of FIGURE 1, and show the flames inclined.
  • FIG- URES 3a, 3b and 3c show the flames vertically directed.
  • the end and side elevation of FIGURES 4a and 4b show an arrangement of three burners with their flames direct ed outwardly.
  • the burner is constituted of an external cylindrical sheath 4, in which are located three guide plates 5 having as many circular holes as there are partial-burners.
  • Each partial-burner has an external cylindrical shape and can rotate or slide in a pair of the holes in the plates 5. It is accordingly possible to adjust the position of the partial-burners somewhat, even during operation.
  • one of the groups of nozzles i s slidable and/or rotatable A multiple fuel bufn'er' do mprising a" body ha ing an outlet end, at least 0nd,:jbbtul'2lting plate on the said outlet end nozzles in the said at least one obturating plate and conduits for supplying "oxygen, liquid fuel and "gaseous fuel to individual'nozzles; the burner having the improvement that the 'nozzles in the said at least one obturating plate are divided into at least two groups each comprising at least one nozzle fed with oxygen, at least one "nozzle fed with liquid fuel, and at least one nozzle fed with gaseous fuel, the supplying conduits for each group of nozzles being independent of the supplying conduits for the remaining nozzles, whereby each group of nozzles constitutes a head of a partial oXy-fuel burner.
  • a burner as claimed in claim 2 in which at least relatiye to the o fhe r groups of nozzlesof the multiple burner, which makes it possible to alter the orientation of the flame formed by the fluids issuing from the said at least one group of nozzles.
