ABSTRACT:
A carbon black reactor having a combustion chamber, a mixing chamber and a reaction chamber positioned along a longitudinal axis of the reactor. The chambers communicate with each other so as to provide a flow path for the hot combustion gases as the combustion gases travel from the combustion chamber, through the mixing chamber and into the reaction chamber. The mixing chamber is designed in the form of an axial narrow area in a dividing wall separating the combustion chamber from the reaction chamber. In addition to the mixing chamber, the combustion chamber and the reaction chamber additionally communicate with each other through at least one bypass bore provided in the dividing wall and positioned radially externally to the mixing chamber and internally to the surface of the combustion chamber. The bypass bores can be either axially aligned so as to be parallel to a central, axial axis of the mixing chamber or inclined. The inclination of the bypass bores can be either in a divergent combustion flow arrangement or a converging combustion flow arrangement. The mixing chamber can either have a constant diameter surface along its length or a surface which narrows in an upstream to downstream direction. The extra-axial bypass bores provide a combustion gas flow, which has not been subjected to the cooling effect of the introduced feedstock, to the reaction chamber in an area radially external to the outlet opening of the mixing chamber.
