Abstract

For guarantee of fire and frame safety at welding and cutting metals is expediently to use instead of acetylene the gas MAAF - methylacetylene-allene fraction. Gas MAAF is a by-product of ethylene’s manufacture. It surpasses the acetylene and propane by various parameters, but inferiors to acetylene only on temperature of burning in the environment of oxygen (2930 instead of 3080°C). The data on physical and chemical properties of MAAF are reduced. It is paid attention to technological features of use of this fraction. It is informed what it is economically profitable to apply the fuel gas MAAF as its one cylinder replaces four cylinders of acetylene. The cost of filled cylinder MAAF is at twice more cheaply than acethylene.
