Definitions

  • the invention relates to an externally mixing fuel gas-oxygen burner for generating a short, fully reacted and hot flame.
  • the nozzle In order to produce an ideal mixture, ie a maximum possible burnout, in the case of external-mixing burners, the nozzle must divide the fuel gas and oxygen into an infinite number of individual jets, which are arranged alternately. Such an arrangement increases the mass transfer area between fuel gas and oxygen, which is the prerequisite for creating a short, fully reacted and hot flame. Technically, however, only a finite number of individual gas and oxygen jets can be assigned to each other for manufacturing reasons.
  • the invention has for its object to achieve the greatest possible division of the gas and oxygen individual jets with little design effort.
  • the fuel gas nozzle consists of a multiplicity of tubes of small diameter and the oxygen nozzle is formed by the free space between the tubes of small diameter .
  • the individual tubes are preferably bundled alternately to form a gap.
  • the oxygen nozzle is therefore inevitably formed by the free cross section between the gas nozzles. This eliminates any design effort for the oxygen nozzle.
  • the small diameter tubes do not touch and are arranged in parallel.
  • a perforated plate with bores is arranged in the exit plane of the tubes, into which the tubes protrude to form annular gaps.
  • the oxygen flows out through the many concentric annular gaps and is swirled intensively with the fuel gas flows. This optimally increases the mass transfer area between fuel gas and oxygen.
  • the externally mixing fuel gas-oxygen burner shown in FIGS. 1 and 2 consists of the burner housing 1, in which an intermediate base 2 is attached.
  • the intermediate floor 2 separates the oxygen indicated by an arrow 3 from the fuel gas indicated by an arrow 4.
  • a plurality of tubes 5 of small diameter are arranged in the intermediate floor 2, which run parallel and do not touch.
  • the space 7 remaining between the tubes 5 serves as an oxygen nozzle, which is delimited on the outside by a nozzle ring 6.
  • the externally mixing fuel gas-oxygen burner shown in FIGS. 3 and 4 essentially corresponds to the burner according to FIGS. 1 and 2, which is why the same reference numerals are used.
  • Only the nozzle ring 6 has been replaced by a perforated plate 8.
  • the perforated plate 8 has holes which are arranged so that the tubes 5 of small diameter for the fuel gas protrude into the holes.
  • the bores are larger than the outer diameter of the tubes 5, so that concentric annular gaps 9 are formed.
  • the oxygen flowing out through the annular gaps 9 is mixed intensively with that from the Tubes 5 emerging individual jets of fuel gas. In this way, the goal of making the mass transfer area between fuel gas and oxygen as large as possible is achieved particularly well.
  • the fuel gas-oxygen burner according to the invention can be used in many technical fields, for example as an additional burner to increase the melting capacity of electrical induction crucible furnaces.
