Definitions
- the present invention relates to a gas mixture ternary containing controlled amounts of propane, butane and acetylene, usable in an operation flame cutting.
- an oxygen cutting operation consists of cutting with a mixture of combustion of a sheet or the like of a material metallic containing a high proportion of iron, for example of steel.
- gases or gas mixtures can be used as a combustible gas, then that we usually use oxygen or a mixture oxygen-rich gas as a fuel gas.
- Fuel gas and fuel gas are mixed to each other to generate the gas mixture of combustion which feeds a burner, i.e. the nozzle a flame cutting torch for example.
- the object of the present invention is therefore to try to to overcome the aforementioned problem, that is to say propose a combustible gas mixture usable in an oxygen cutting operation, which gas mixture leads at preheating times before cutting proper significantly lower than those obtained with mixtures gaseous conventionally used.
- the butane is iso-butane, n-butane or a mixture of iso-butane and n-butane.
- the ratio of the proportion of butane the proportion of propane is at least 0.25 of preferably 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 mixture ternary gas and the use of said gas mixture ternary in an oxygen cutting operation, as a gas fuel intended to be mixed in a proportion desired oxygen or a gas mixture containing oxygen, like air.
- a combustion gas mixture by mixing desired proportions of a ternary gas mixture according to the invention and oxygen or a gas containing oxygen, preferably the combustion gas mixture is carried out in a gas mixer or directly in a nozzle or a burner.
- gas mixtures ternaries according to the invention were used as combustible gas in an oxygen cutting operation of a metal sheet 20 mm thick.
- the fuel gas used is oxygen.
- the time was determined preheating, i.e. the time required for the effective preheating of the sheet to cut.
- the ratio of the proportion of butane to that of propane is 0.66.
- the ratio of the proportion of butane to that of propane is 0.43.
- the ratio of the proportion of butane to that of propane is 0.25.
