Abstract
The present invention features a center feed system in combination with a coking vessel of a delayed coking system, or any other similar system. 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 the vessel, thus effectuating or inducing even thermal distribution throughout the vessel. The retractable nozzle is structured to extend through an opening in the coking vessel while introducing the residual byproduct into the coking vessel and retract out of the coking vessel and cover the opening for at least a portion of a coking cycle.
