Q. I have a job on which it is difficult
to clean up the fire. What should I do?
- Check the fire to see whether it is off center (see discussion of off
center fires next question).
- Check the fan blades and if they are covered with lint and dirt, clean
- If this is a conventional oil burner, check for a burned-off end cone.
- Check the oil pressure to be sure that it is at least 100 PSI.
- Check for a plugged line filter or pump strainer.
- If the smoke is at the outside edges of the fire, try a narrow angle
- If the smoke occurs at the end of the fire, it might be well to try a
wider spray angle.
- The burner may have insufficient air capacity for this firing rate.
- The burner may have too high air capacity for this firing rate. This
would mean that the burner head couldn't handle a low firing rate.
- It might just be a very inefficient burner, which cannot be made to
- The nozzle may be partially plugged, resulting in poor atomization.
- The oil may have a high viscosity or it might be cold, resulting
in a collapsing spray.
- Get sufficient air into the boiler room. If necessary, put in an air
intake pipe with a screen and storm cover.
