VARIANTS The GLE burner is a "pre-packaged LE" configured to fire oil field steam generators at 62.5, 85 or 100 MM Btu/h HHV. It is supplied with a pre-piped 4020 pilot, ignition cable, NEMA 4 ignition transformer; 3 pre-piped, pre-wired, pre-set, pressure switches (for purge, low combustion air, and low fire proving); and a junction box for wiring to the necessary control hard- ware, simplifying installation and field start-up.
The LEx burner is the LE without the secondary fuel injectors. It operates at excess air rates between 60-80% at a standard input ranging from 3 to 200 MM Btu/h HHV with larger sizes available (e.g. 400 MM Btu/h built for a calciner). It is intended for lower temperature applications where secondary air is normally employed to achieve process temperatures between 300-1600°F. LEx burners normally require an extended primary zone reaction chamber to protect the flame from the lower temperature secondary process stream. See Bulletin 4213 for more information.
