The process of burning out of a torch of gas fuel in a wide range of change of the influence parameters was analyzed, which allows valid consideration of the thermal calculations of industrial units. The differential equation of burning out of the one-dimensional torch and its decision were received, on the basis of which the equations for calculation of the degree of burning out and length of the torch were deduced. Research of the influence of change of the theoretical volume of oxygen was conducted, which allows valid consideration of the calculations of burning out of gas fuel in industrial units.
