Definitions
- the present invention relates to a gas or ternary mixture containing controlled quantities of propane, butane and acetylene, which can be used in an oxygen cutting operation.
- an oxygen cutting operation consists in making a cut with a combustion mixture of a sheet or the like from a metallic material containing a high proportion of iron, for example steel.
- the combustible gas and the fuel gas are mixed with each other to generate the combustion gas mixture which feeds a burner, that is to say the nozzle of an oxygen cutting torch for example.
- the object of the present invention is therefore to try to alleviate the aforementioned problem, that is to say to propose a combustible gas mixture usable in an oxygen cutting operation, which gas mixture leads to preheating times before cutting proper significantly lower than those obtained with the gas mixtures conventionally used.
- the invention therefore relates to a combustible ternary gas mixture consisting of:. 10 to 40% acetylene. 10 to 50% butane, and. 10 to 80% propane
- the gas mixture contains:. 15 to 30% acetylene. 14 to 43% of butane, and. 27 to 71% propane
- the gas mixture contains:. 20 to 30% acetylene
- the butane is iso-butane, n-butane or a mixture of iso-butane and n-butane.
- the ratio of the proportion of butane to the proportion of propane is at least 0.25, preferably from 0.25 to 0.66, and / or the proportion of butane is less than or equal to the proportion of acetylene.
- the proportion of acetylene is between 20 and 30%.
- the invention also relates to a container, in particular a gas cylinder containing such a ternary gas mixture and the use of said ternary gas mixture in an oxycutting operation, as combustible gas intended to be mixed in a proportion desired oxygen or a gaseous mixture containing oxygen, such as air.
- a combustion gas mixture is produced on site, by mixing desired proportions of a ternary gas mixture according to the invention and of oxygen or of a gas containing oxygen, preferably the combustion gas mixture is produced in a gas mixer or directly in a nozzle or burner.
- a gas mixer or directly in a nozzle or burner.
- ternary gas mixtures according to the invention were used as combustible gas in an oxycutting operation of a metal sheet 20 mm thick.
- the fuel gas used is oxygen.
- the preheating time was determined, that is to say the time necessary for effective preheating of the sheet to be cut.
- the ternary gas mixture contains:
- the ternary gas mixture contains:
- the results obtained show that the use of this ternary gas mixture leads to a saving in preheating time of 65% compared to butane and 45% compared to propane.
- Example 3 The ternary gas mixture contains:
- the ratio of the proportion of butane to that of propane is 0.25.
