A fuel mixture, which contains by volume 15 to 25% acetylene, 5 to 17% C.sub.3 hydrocarbon, preferably propylene, and the remainder ethylene. This ternary fuel having a fairly constant acetylene content, is suitable in applications pertaining to assembly, flame heat treatment, flame metal spraying and disintegration of inorganic compounds or cements.

Ternary fuel having fairly constant acetylene content in the liquid and

A stable cryogenic fuel mixture containing 25 to 30% by volume of acetylene, 61 to 72% by volume of ethylene and 3 to 9% by volume of a C.sub.3 hydrocarbon preferably propylene. This fuel mixture having a density in the gaseous state, which is less than the density of air, is particularly suited for use in welding and assembly operations.
