Apparatus for producing carbon black

Claim 1

An injection assembly for introducing a normally liquid hydrocarbon feedstock into a carbon black producing furnace, which comprises: a pipe shroud member having an upstream and downstream closure end; a feedstock supply pipe concentrically disposed within said shroud member adapted to be rotatably and longitudinally positioned therein and whose upstream end projects beyond the upstream closure end of the shroud member; a cylindrical manifold rigidly attached to and in open communication with the downstream end of said feedstock supply pipe and the header end of which is provided with a centrally located circular port and a plurality of like ports circumferentially disposed thereabout; a metallic feedstock supply tube rigidly connected to and in axial alignment with said centrally located circular port and projecting beyond the shroud member downstream closure end; a metallic feedstock supply tube rigidly connected to and in axial alignment with each of said circumferentially disposed ports via a segment of metallic flex tube the combined length thereof being about that of said centrally disposed feedstock supply tube; and a spreader plate forming the downstream rigidly affixed closure end of the shroud member and which is perforated and positioned to accommodate freely the longitudinal passage of said feedstock tubes.
