ABSTRACT:
An apparatus for producing carbon black is comprised of an elongate outer housing having mounted therein a tubular member having a flow passage therethrough which forms a reaction zone of the apparatus. At the upstream end of the reaction zone, a perforate cage is provided which has a plurality of perforations through which air enters the interior of the cage to form a vortex flow path. The side wall of the cage is spaced from the interior surface of the housing providing an air flow path therebetween. The upstream end of the cage is a wall and has a centrally located opening therethrough which has an annular ring projecting therefrom to form a seal with another annular ridge which is in sliding and sealing engagement therewith. The seal prevents entry of air through the opening from the annular flow path to the interior of the cage. Coaxial tubes extend through the opening and into the cage and are operable to introduce fuel and make oil thereinto.
