has a 10:1 turndown. Burners equipped for high turn-
down (greater than 6:1) can have different equipment to
improve fuel, air and FGR flow control.
3. Product Offering
The JBE burner can fire a variety of different vessels,
fuels and NOx levels. When fired in any boiler except a
scotch marine firetube boiler, a refractory shape is used
to contain the flame, and looks like a “tube”. The burner
can fire natural gas, LP, digester and other types of gas,
as well as #2 through #6 fuel oil. See Figure A-4 for
minimum furnace sizes.
DO NOT USE GASOLINE, CRANKCASE OIL OR ANY
OIL CONTAINING GASOLINE.
This burner is also available as a low emission burner,
and will have model designation JBEX. Several low NOx
rates are available for all gas and light oil burners, with
the standard offering of 60 ppm, 30 ppm and 20 ppm
when firing natural gas. Low sulfur heavy oil can be
used with gas FGR, when the sulfur is under ½% (the
FGR is closed during oil firing).
4. Your Complete Manual
In addition to this manual, there are several other
documents that should be considered as part of the
complete manual for the burner. All of these documents
are needed to support the installation and startup of the
unit. These additional items include:
a.
The wiring diagram, which shows the limits and
interconnection of the burner and vessel controls.
b.
The gas and oil piping schematics, which show the
components and their relative positions in the piping
train.
c.
The unit material list which provides an overview of
the burner requirements and a complete bill of
material, including the part numbers and description
for each item.
d.
The flame safeguard manual provides the operating
sequence for the burner management system. This
will be a critical document for troubleshooting any
future problems.
e.
Catalog cuts of the major components. These
provide details on the installation, adjustment and
maintenance of the components used on the burner.
