Adjustments Concerning Nozzles
Annual replacement of the nozzle is recommended. The nozzle
size should match the design load. DO NOT OVER SIZE. (For
determination of over sizing refer to publications listed on page 8.)
Short cycles and low percent “on” time result in higher overall
pollutant emissions and lower thermal efficiency.
An in-line oil filter will reduce problems due to nozzle clogging. It
should be located as close as possible to the oil burner. Care
should be taken to prevent air leakage into the oil suction line. Use
continuous runs of copper tubing and use minimum number of
joints and fittings. Always use flare fittings. Select the nozzle and
spray pattern, whenever possible, using burner manufacturer’s
instructions. On burner-boiler or burner-furnace matched
assemblies, use the appliance manufacturer’s instructions. Bleed
air from the pump and nozzle piping to avoid trapped air.
Good Filtration Is Important
We’ve been saying the nozzle is the heart of the oil heating system
and it is critical to prevent nozzle contamination. Good filters will
remove extraneous dirt in the oil, as well as rust and sludge that
form in the fuel tank and could plug the nozzle slots or orifice.
Check the line filter between the tank and pump, and replace it
frequently. After working on the system, flush a pint of oil through
the oil line to get rid of any stirred-up sediment. Use properly
sized filters and strainers on the nozzle. A Delavan line filter on
installations under two gallons-per-hour flow is also
recommended.
