Abstract
A concentric burner and feedstock injection assembly, for a carbon black reactor, designed for the atomizing and burning of liquid fuels to provide the heat required for the reaction. The atomizing tip consists of two annular rings machined to form a throat having a generally converging annulus through which part of the combustion air, brought first into strong swirling motion, is accelerated and passes as an air stream having a hollow, frusto-conical, divergent pattern. Fuel oil is injected, through a plurality of holes drilled through the inner annular ring, into said air stream and is atomized by said stream. The balance of the combustion air is supplied to the combustion chamber which surrounds the burner and is in communication with the reaction zone of the reactor. Feedstock oil is injected into the reaction chamber through a tubular subassembly inserted through a central opening in the assembly.
