ES392638A1 - Burner and feedstock injection assembly for carbon black reactor - Google Patents

Abstract

Improved burner and feed material injector for a carbon black reactor, the assembly of which is concentrically arranged within an elongated and substantially tubular carbon carbon black reactor, at an upstream end, comprising a central pipe for introducing feed material into the reactor, terminating one end of said pipeline within the reactor and being equipped with a spray nozzle, a second pipeline concentrically arranged around the central pipeline, terminating one end of this second pipeline approximately flush with the end of the central pipeline inside the reactor, a third pipeline that ends at one of its ends inside the reactor at a point upstream from the end of the central pipeline, a series of fuel oil pipes arranged within the angle between the second and third pipes and axially parallel to them, ending ta The fuel oil pipes at a point within the reactor downstream from the end of the third pipe, but upstream from the end of the central pipe, the ends of the fuel oil pipes connecting to a series of fuel spray nozzles, each one of which is inclined at an angle of approximately 15 to 45º with respect to the axis of the central pipe, means for supplying carbon black feed material to the central pipe, means for supplying a coolant to the annulus between the first and second pipes, means for supplying a normally liquid hydrocarbon fuel to the fuel oil pipes, means for introducing a process air stream into the reactor and means for directing said downstream process air stream along the outside of the third pipe.
