CENTER FEED SYSTEM EMPLOYING REMOVABLE INSERTS IN A RETRACTABLE INJECTION NOZZLE
First Claim
1. A center feed system comprising:
- an inlet sleeve configured to attach to a vessel; and
a retractable injection nozzle contained within the inlet sleeve, the retractable injection nozzle sliding within the inlet sleeve to extend into and retract from the vessel for introducing residual byproduct into the vessel, the retractable injection nozzle including one or more openings that are exposed within the vessel when the retractable injection nozzle is extended, the residual byproduct exiting the retractable injection nozzle through the one or more openings;
wherein the one or more openings each include an insert that can be removed from the opening.

Abstract
The present invention extends to a center feed system that 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 in accordance with one or more embodiments of the invention 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.
