Retractable Center Feed Injection Device

CenterFeed

Side Feed Entry, Bottom Feed Results

DeltaValve’s retractable center-feed injection device was developed to combine the benefits of traditional bottom center feed with the advantages of side-feed entry.  This technology creates uniform, centered flow channels which reduce the rate of temperature change at the drum wall, reducing overall coke drum stresses, top head blowouts, and premature drum failure.

Key Advantages
  • Facilitates side feed drum entry
  • Flow channeling up the center of the coke drum
  • Reduced coke drum stress, warping, and bulging
  • Reduced hot-spots, top head blowouts, and eruptions
