An improved process of producing carbon black by pyrolysis of a hydrocarbon charge injected into a mass with turbulent movement of very hot combination gases, characterized by burning a fuel with gas containing free oxygen, introducing the resulting hot combustión gases into a converging frustoconical section forming part of the reaction chamber of the furnace, thus forming the hot gases in a conical whirlwind that rapidly rotates with a substantial cavity and progressively narrows as the gases move towards the exit of the frustoconical section, and introducing the hydrocarbon charge directly into the frustoconical section at a point between the ends thereof so that the hydrocarbon enters the mass of the vortex adjacent to the inner wall of the frustoconical section, with the combustión of the fuel substantially complete in the point at which the hydrocarbon charge enters the c whirlwind body.
