Abstract
A center feed system allows residual byproduct to be injected into a vessel from within the center of the vessel. The center feed system can include an inlet sleeve that is attached to the vessel and a retractable injection nozzle that extends into the vessel to inject residual byproduct into the vessel and that retracts into the inlet sleeve after injecting the residual byproduct. A retractable injection nozzle may include one or more openings that each includes an insert that can be removed from the opening. The inserts can therefore be replaced to customize the functionality of the nozzle or to replace the inserts when they have become worn.
