TROUBLE-SHOOTING
PROBLEM POSSIBLE CAUSE SOLUTION
• Fuel pressure too high at burner inlet.
• Combustion air pressure drop/flow is
too low.
• Combustion air pressure drop/flow is
too high.
• Burner is firing below rated input.
• Burner gas holes/oil ports are plugged.
• Air pressure drop/flow is lower than
design.
• Windbox air flow is restricted.
Too much air.
Orifices in the oil tip are plugged.
• The oil is too cold.
• The atomizing medium pressure is too
low.
Moisture (condensate) in the atomizing
medium.
Poor atomization.
Oil nozzle is too far forward into the
throat.
Main flame is too large at high fire.
Main flame does not achieve
capacity.
Main flame is yellow and long (in gas
applications)
OR
Main flame appears a dull orange
color (in oil applications).
Main oil flame is white and hard.
Uneven oil flame with stingers
shooting out to one side of the block.
Orange or red “sparklers” in the oil
flame.
Flame temporarily becomes black
and smokey, then clears up again
OR
Flame sputters and goes out
momentarily.
Fiery ring of burning oil on the inside
diameter of the combustor surface
OR
Carbon deposits on the inside of the
refractory block.
Carbon accumulation on the oil
nozzle cone.
Check fuel pressure against design.
Adjust main fuel pressure regulator, or
adjust control valve.
Open air damper on main air blower.
Check pressure drop or flow. Check
air damper on main air blower.
Check fuel pressure differential/flow.
Adjust main fuel pressure regulator as
necessary.
Inspect holes/ports for blockage; clean
as needed.
Check pressure drop or flow. Open air
damper on main air blower.
Inspect windbox and blower to ensure
that no foreign material is restricting
the air flow.
Check combustion air pressure drop/
flow. Close control damper as necessary.
Remove oil nozzle and clean as necessary.
Check oil heating system; increase
temperature as necessary.
Check existing atomizing pressure
versus required (see table in Appendix).
Ensure that the condensate trap is
operating properly for atomizing steam.
Install dryers in the atomizing air line.
Check atomizing pressure and adjust as
necessary.
Check oil nozzle ports for clogging.
Move gun back 1/4" at a time until
carbon no longer accumulates.
