Description

The Delavan 30609-008 is an oil nozzle designed for use in various heat generators. It atomizes fuel oil into a fine spray cone to ensure complete combustion. This nozzle is a consumable precision part, selected by flow rate, spray angle, and spray pattern. It is a wear item and should be replaced annually or per the service manual.

Choosing and fitting

Parts of this type are selected by three parameters: flow rate (given in USGPH or kg/h at a reference pressure), spray angle (typically between 30° and 80°), and spray pattern (hollow cone, solid cone, or semi-solid cone). The thread size must also match the burner adaptor. All three ratings must match the burner manufacturer's specification as stamped on the burner data plate. When replacing, ensure the old gasket or copper washer is removed and a new one fitted; overtightening can distort the nozzle body and alter the spray.

Signs of failure

Fitting a nozzle with the correct flow rate but an incorrect pattern leads to sooting, unstable ignition, or pressure pulsation in the combustion head. These symptoms indicate a mismatch in spray pattern or other parameters. Check the nozzle's ratings against the burner data plate and inspect for wear or damage.
