A center feed system for use within a delayed coking system, or any other similar system is described. The center feed system features an inlet sleeve which slidably engages a retractable nozzle, with inlet and outlet, in fluid connection with a feed source of residual byproduct, allowing residual byproduct to flow from the feed source into the interior of a vessel, thus effectuating or inducing even thermal distribution throughout the vessel.

1. A center feed system for coking a drum comprising: an inlet sleeve attached to a sidewall of a reservoir vessel; anda retractable injection nozzle contained within the inlet sleeve, the retractable injection nozzle adapted to extend into the reservoir vessel to allow residual byproduct to flow therethrough and into the reservoir vessel, and adapted to retract from the reservoir vessel and into the inlet sleeve, wherein the retractable injection nozzle is shaped such that retracting the retractable injection nozzle into the inlet sleeve blocks the flow of residual byproduct through the retractable injection nozzle, and wherein the retractable injection nozzle includes a fluid obstruction apparatus. 2. The center feed system of claim 1, wherein the retractable injection nozzle includes more than one outlet through which the residual byproduct flows out into the reservoir vessel. 3. The center feed system of claim 2, wherein the retractable injection nozzle includes two outlets. 4. The center feed system of claim 1, wherein the fluid obstruction apparatus is selected from a group consisting of: a tapered collar, a baffle, a non-tapered collar, and a collar body. 5. The center feed system of claim 4, wherein the tapered collar comprises a tapered collared inlet, a collar body and a collar outlet. 6. The center feed system of claim 4, wherein the non-tapered collar body comprises a tapered collared inlet, a collar body and a collar outlet. 7. The center feed system of claim 1, wherein the fluid obstruction apparatus comprises an outlet with multiple holes. 8. The center feed system of claim 1, wherein the inlet sleeve comprises one of: a shaped four-way pipe segment or a curved pipe segment. 9. The center feed system of claim 1, wherein the retractable injection nozzle is cylindrical in shape. 10. The center feed system of claim 1, wherein the retractable nozzle comprises a first end attached to an actuator, and a second end structured to form a portion of the interior wall surface of the reservoir vessel when retracted. 11. The center feed system of claim 1, wherein at least one of the retractable injection nozzle or the inlet sleeve has a varying cross-sectional area. 12. The center feed system of claim 1, wherein at least one of the retractable injection nozzle or the inlet sleeve has a constant cross-sectional area. 13. The center feed system of claim 1, wherein said reservoir vessel is a coke drum. 14. The center feed system of claim 1, wherein said reservoir vessel is a spool attaching at least two flanged components together. 15. The center feed system of claim 1, wherein one of said inlet sleeve and said retractable injection nozzle has a varying cross-sectional area along its span to provide for and accommodate varying volumes of said residual byproduct. 16. The center feed system of claim 1, wherein said residual byproduct is dispensed within said reservoir vessel at an angle selected from the group consisting of between 0 and 90 degrees, between 20 and 30 degrees, between 30 and 60 degrees, and between 60 and 90 degrees. 17. The center feed system of claim 1, further coinrpising: the reservoir vessel to which the inlet sleeve is attached. 18. The center feed system of claim 17, wherein the reservoir vessel is a coke drum, or a spool that is configured to attach to a coke drum. 19. A center feed system for coking a drum comprising: a spool that is configured to attach to a coke drum;an inlet sleeve attached to a sidewall of the spool; anda retractable injection nozzle contained within the inlet sleeve, the retractable injection nozzle adapted to extend into the spool to allow residual byproduct to flow therethrough and into a coke drum to which the spool is attached, and adapted to retract from the spool and into the inlet sleeve, wherein the retractable injection nozzle is shaped such that retracting the retractable injection nozzle into the inlet sleeve blocks the flow of residual byproduct through the retractable injection nozzle, and wherein the retractable injection nozzle includes a fluid obstruction apparatus. 20. The center feed system of claim 19, wherein the fluid obstruction apparatus is selected from a group consisting of: a tapered collar, a baffle, a non-tapered collar, and a collar body.
