Abstract
Peculiarities of utilization of hydrogen-oxygen flame in flame treatment of materials are generalized, the flame being formed by combustion of a mixture produced by electrolysis-water generators. The study shows that it is possible to regulate the reduction potential of the combustion product flame with respect to iron, and control the overall thermal power due to saturation of the mixture with hydrocarbon additions.
