Improved Ferrule and Tube Design for Prevention of Film Boiling in SRU Waste Heat Boiler

In November 2005, an improved tube and ferrule design was installed into a boiler in the CITGO Corpus Christi Refinery East Plant SRU unit. 12 years later, the performance of the improved tube and ferrule design was considered successful as the heat flux lowered enough to avoid film boiling.

Learn about the results that this plant has realized utilizing a patented ferrule design in cooperation with Blasch, including:

  • lower heat flux
  • longer tube life
  • lower pressure drop
