Abstract (en)
[origin: FR2774693A1] The invention concerns a fuel mixture containing acetylene, propane and propylene, such that the ratio Qp/Qa of the proportion (Qp) of propane and propylene to the proportion (Qa) of acetylene is such that: 1.1</=Qp/Qa</=4. Preferably, the propane/propylene proportion in the gas mixture ranges between 50:50 and 99:1. Advantageously, the gas mixture contains 15 % to 50 % by volume of acetylene, the remainder being propane and propylene. The invention is applicable to a fuel mixture for oxyacetylene cutting of metals, the fuel mixture being produced on the site of operation, in particular in a gas mixer.
