7. If the burner is not being used for an extended time,
plug or cover the block opening with mullite or a
bonded AZS block instead of fiber wool.
8. If the burner is to be left out of service, close all
service valves on the metering and control skid.

Ensure
that
all
lock-out
and
tag-out
procedures
are
in place according to your plant procedures.
NOTE:
Whenever removing a burner from service, always
keep the oxygen-compatible components cleaned and
sealed. Hoses should be capped when not used. Burners
should be cleaned and stored in a sealed plastic bag.
Inspecting the Burner
Each shift should inspect the Primefire burners just as you
would inspect firing conditions in your present furnace.
Use these guidelines to inspect the burners, blocks, and
operation.
Recommended checks:
• Flame shape and appearance
• Burner block appearance
• Proper cooling effect on burner and block
• Combustion oxygen flow
• Atomizing oxygen flow and pressure
• Fuel oil flow and pressure
Obvious changes from the standard should be
investigated. If needed, fuel should be shut off with
combustion and atomizing oxygen set to a minimum while
the situation is investigated.
Maintaining the Burner
Under normal operating conditions, the Primefire oxy-oil
burner should need little attention. If you need to remove
and inspect a burner, use this procedure.
1. Follow the steps above under Burner Shutdown and
Removal.
2. The oxygen tip can be viewed and inspected. See
Figure 1.2 on page 4.
3. To remove the atomizing assembly:
a.Remove the ball lock pin.
b.Gently pull the atomizing assembly out of the
burner body.
3. The oil tip can be removed by loosening the oil boss
at the rear of the tube, then pulling the oil tube out.
4. To view and inspect the intermediate tip, remove the
roll pin from the burner adjustment screw and pull the
tube out of the burner body. See Figure 3.2
NOTE:
The o-rings are used for sealing between the oil
and atomizing oxygen tubes, the intermediate and
atomizing oxygen tubes, and the intermediate and
combustion oxygen tubes. See Figure 1.1, 3.1 and 3.2.
Use only Eclipse supplied halocarbon grease on the o-
rings to ensure oxygen compatibility. Also make sure the
surfaces that mate with the o-rings are kept clean and are
not scratched. A damaged surface can cause a leak.
Cleaning the Burner Parts
After the burner is disassembled, use the following
procedure to clean the parts.
1. Using compressed air and cleaning solvent, clean the
oil tube tip.
Handle all tips carefully to prevent damage.
2. Wipe the oil tube clean.
3. Clean the atomizing oxygen tube with appropriate
oxygen cleaning solvents. Wipe the tube clean when
done.
4. Clean all oxygen-compatible components and wipe
clean when done; reassemble the burner by reversing
the disassembly instructions under Burner
Maintenance.
When reassembling the burner:
• Examine all o-rings and apply fresh halocarbon
grease.
• Use the centering lugs for the oil tube, atomizing
oxygen tube, and intermediate tube to ensure the
respective tube is in the proper centered location for
efficient mixing.
NOTE:
Be careful not to damage the sealing surface on
the atomizing tube assembly. A damaged surface can
cause a leak.
• Verify the oil tip is in the correct position, and is
locked in position.
Always store the burner in a sealed plastic bag. This will
ensure that the burner is oxygen-compatible and ready to
fire.
