2012 European Ethylene Producers Conference (EEPC) – October 24-26, 2012 – Barcelona, Spain
Problem:
- Cracking furnace must be retrofitted with new hearth burners to meet lower NOx requirements (150 mg/Nm3)
- Tight burner spacing
- Flame rollover is not acceptable
Technology Used
- Zeeco “EnhancedJet” Ultra Low NOx Burner
- Secondary tips inspirate inert flue gas into flame
- Capable of sub 100 mg/Nm3 NOx emissions
Burner Design
- Secondary tips fire into flue gas, inspirating flue gas into the flame
- Primary gas tips provide “fuel staging” and allow for tuning of heat flux profile
