Definitions

  • the present invention relates to a stable ternary fuel with a density in the gaseous state lower than the density of air.
  • the more volatile component than acetylene is ethylene.
  • the third constituent chosen so as to bring about the stabilization of the liquid phase is a hydrocarbon whose molecule contains three carbon atoms, said hydrocarbon being part of the group consisting of propane, cyclopropane and propylene and the choice preferably being directed to unsaturated hydrocarbon.
  • liquefied fuel mixtures for welding or cutting are known, composed of acetylene, ethylene, propylene and / or propane, with a relatively high content of ethylene and C 3 hydrocarbon and fairly low in acetylene, of which the reports are in the area delimited by the four points A (54.6-40), B (36.6-23, 4), C (18.3-11.7-70) and D (27.3- 70) in a ternary diagram.
  • the cryogenic ternary fuel consisting of a mixture of acetylene, ethylene and a C 3 hydrocarbon in the following proportions: 25 to 30% by volume of acetylene, 61 to 72% by volume d ethylene and 3 to 9% by volume of the C 3 hydrocabide is used in the gaseous state after vaporization of the mixture stored in the liquid state.
  • This combustible mixture is particularly suitable for welding and assembly operations.
  • the density in the gaseous state is always lower than that of air, even when an alternate sampling of the gaseous phase of the storage tank or of vaporization of the liquid is carried out, this under normal operating conditions, it is that is to say when, at the maximum, the ratio of the quantity withdrawn in phase gaseous to that withdrawn by the liquid phase remains less than 1.
  • the stability of the fuel mixture is suitable for industrial use in large quantities.
  • the low enrichment in acetylene, during slow evaporation, allows the distribution of said mixtures in bulk or in small conventional cryogenic evaporators, free of copper or copper alloys.
  • Transport and decanting are more advantageously carried out, the product being in the liquid state.
  • the fuel mixtures of the invention when the C 3 hydrocarbon is propylene, are shown in the ternary diagram appended in FIG. 1.
  • the contents of acetylene, ethylene and propylene are given as percentages by volume.
  • the properties of density lower than air in the gas phase and of low enrichment in acetylene are perfectly preserved in the quadrilateral A 'B' C 'D' located below the straight line FG representing the mixtures of density equal to air.
  • the preferred field of use corresponds to a cryogenic mixture containing approximately 26% of acetylene, approximately 69% of ethylene and approximately 5% of propylene.
