Delavan Atomizing nozzle 30609-006

The Delavan 30609-006 is an atomizing nozzle designed for oil and viscous fuels, producing a solid cone spray pattern. It is constructed from brass and stainless steel, featuring large passage openings to resist clogging and a conical nozzle head. The nozzle is installed on universal threads and includes a hex body for wrench tightening. It is supplied in a protective case for safe transport.

When selecting a replacement nozzle of this type, the flow rate (in US gph or kg/h at a reference pressure, typically 7 bar or 100 psi), spray angle, and spray pattern must match the burner's specifications. The thread size must also correspond to the nozzle adapter. These parameters are typically found on the burner's data plate or manufacturer's specification.

Nozzles of this kind can wear or clog from fuel deposits, leading to poor combustion, sooting, pulsation, or ignition failure. Regular replacement is part of standard burner maintenance to avoid these issues.
