PROBLEM TO BE SOLVED: To provide (1) an apparatus for producing carbon black designed to raise the contact efficiency of a high-temperature combustion gas stream with a raw material oil and improve the conversion yield into the carbon black and to provide (2) the apparatus for production designed to inexpensively mass-produce the carbon black having characteristics of a smaller distribution width of an aggregate which is the minimum dispersion unit into a matrix measured by a centrifugal settling analysis than the conventional width. SOLUTION: The apparatus for producing the carbon black is composed of a combustion zone for burning a mixture of a hydrocarbon fuel with an oxygen-containing gas and thereby producing the high-temperature gas stream, a reaction zone for feeding a raw material hydrocarbon in a plurality of divided streams into the high-temperature gas stream produced in the combustion zone and producing a carbon black-containing gas stream by the pyrolysis and/or incomplete combustion thereof, and a quenching zone for spraying cooling water on the reaction gas stream from the reaction zone and stopping the reaction. In the apparatus for producing the carbon black in which the whole is transversely placed, the cross-sectional shape when an introduction part for the raw material oil in the reaction zone is cut at right angles from the longitudinal direction is a non-circular and non-polygonal form.
