NOZZLES for WASTE (used) OIL BURNERS

An oil burner nozzle is an intricate piece of hardware, designed to do an accurate job of atomizing and metering fuel in the spray pattern best suited to a given burner. You can help assure top performance of this vital component by following the important guidelines in this section.

Until installation, keep spare nozzles in their original containers.
They should not be permitted to roll around in a drawer or toolbox, or carried loose in pockets. To decrease burner down time it is recommended to have spare nozzle(s).

Nozzles should always be handled with clean tools…
to reduce the possibility of contamination.

Before installing a new nozzle, it is very important to flush the fuel line(s) of the burner and nozzle adapter with at least a pint of oil pumped through it to remove sludge and dirt. Or you can blow out the line with compressed air.

The nozzle orifice is polished to a glasslike finish.
Don’t ruin it with a wire or pin, or by bumping it with a wrench. This can cause streaks in the spray.

Don’t blow into the nozzle.
While this may seem to be the handiest and quickest way to “clean” a nozzle, you run the risk of contaminating it instead.

A nozzle can become overheated due to back pressure in the combustion chamber.
This results in coke and sludge formation both inside and outside of the nozzle. To correct this problem, set the over fire draft for at least .02 inches of water column or follow furnace or boiler manufacturer’s specifications.

Make sure the fuel tank is clean.
Water and sludge in the tank can clog lines, filter or nozzles.

Nozzle Cleaning.
A quality nozzle should last through a normal heating season if reasonably clean fuel is supplied to it. To decrease burner down time it is recommended to have spare nozzle(s). Use compressed air for cleaning purposes.
