FIELD: process engineering.
SUBSTANCE: invention relates to formation of hot oxygen jet. Hot oxygen jet is formed by making the channel and fuel pipe to be displaced along the axis inside said channel. Fuel gas flows from said pipe into said channel to be mixed with oxidizer gas. Said mix flows from said channel into atmosphere sufficiently hot to mix ignition without ignition source other than atmosphere. Said mix is combusted in the flame not propagating into said channel. Thereafter, said pipe is displaced to move fuel outlet towards to the channel outlet nozzle. Thus, flame root displaces inside said channel towards fuel outlet. Now, pipe is displaced to shift fuel outlet and flame secured thereto from outlet nozzle into aid channel.
EFFECT: formation of hot oxygen jet.
