Method for heating the reducing gas of a blast furnace by means of a plasma generator. The reducing gas flows through a pipe into which issues the nozzle of the plasma generator.

The method is characterized in that the acute angle A between the axis of the nozzle and the axis of the pipe is at the most equal to 50.degree., in that the distance 1 separating the point of intersection of the axis of the pipe with the axis of the nozzle from the center of the outlet orifice of the nozzle is at the most equal to
