ABSTRACT:
A reaction chamber equipped with external heat exchanging coils for limiting the range of the reaction temperature, which must not go over 1200.degree. C nor below 900.degree. C, is supplied with hydrocarbon reagent and combustion-supporting reagent (air) in a way designed to enable a partial combustion reaction by which carbon black is formed to provide the main source of heat for maintaining the reaction temperature. At the entry end of the reaction chamber is a header providing a multiplicity of ante-chambers through which the reagents flow in a direction parallel to the axis of the reaction chamber while being heated up by heat from the reaction chamber. When a liquid reagent is used, it is atomized in the ante-chambers and vaporized and mixed with air in its passage through the ante-chambers. The air is preheated by a heat exchanger that cools the reaction products after a preliminary cooling by another heat exchanger. Liquid hydrocarbon reagent, when used, is heated and pressurized before distribution to the ante-chambers. When a hydrocarbon gas is used, it is mixed with air in a mixer apparatus interposed in the air supply ahead of the preheating heat exchanger. A separate heater is used to heat the reaction chamber up to reaction temperature. Controls are provided to regulate the hydrocarbon-air ratio of the reagent feed system.
