Title: Apparatus for the production of carbon black

Abstract: Furnace black is produced by a thermal splitting of a carbon black forming oil by oxidation of a fuel in a combustion chamber with production of a stream of hot combustion gases, introduction of this stream in a constricted mixing chamber narrower than the fuel chamber, inserting the carbon black forming material into the mixing chamber and conveying the mixture into an enlarged reaction chamber compared to the mixing chamber as well as quenching the carbon black containing reaction mixture, the stream of hot combustion gases being introduced into the mixing chamber via an annular channel or introducing the stream into an annular channel shaped mixing chamber and spraying in the carbon black forming material into the mixing chamber or ring conduit from within outwardly.
