VARIANTS
The 4231 GLE burner is a "pre-packaged LE" confi gured to fi re
oil fi eld steam generators at 62.5, 85 or 100 MM Btu/hr. 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 fi re proving);
and a junction box for wiring to the necessary control hard-
ware, simplifying installation and fi eld start-up.
The 4213 LEx burner is the 4211 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 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 be-
tween 300-1600°F. LEx burners normally re- quire an extended
primary zone reaction chamber to protect the fl ame from the
lower temperature secondary process stream. See Bulletin 4213
for more information.
