64 F 4007 Oil Nozzle (14kg.) Buyer's Guide for Singapore Industry

The 64 F 4007 oil nozzle (14kg.) is a 14 USgph-class pressure-jet atomising nozzle for oil-fired burners. Buyers in Singapore should treat the 14 USgph flow rating, spray angle and cone pattern as the three defining specifications, then verify them against the burner OEM's commissioning data before purchase.

What is a 64 F 4007 oil nozzle (14kg.)?

A 64 F 4007 oil nozzle (14kg.) is a pressure-jet oil burner nozzle that atomises fuel oil into a fine spray at a rated flow of approximately 14 US gallons per hour (USgph). The '14kg.' suffix in trade listings refers to the shipping/pack weight class, not the flow rating — always confirm the USgph figure on the nozzle body or datasheet.

In 3G Electric's Singapore stock, the closest equivalents are Jetoil and DELAVAN pressure-jet nozzles spanning 0.35–25 USgph and 45–80° spray angles. Brand examples include [[PRODUCT:JTO12080|Jetoil 14.00 45° S and DELAVAN Type A hollow-cone 60° boiler nozzle.

Definition: An oil burner nozzle is a precision-machined orifice assembly that meters and atomises fuel oil into a controlled spray cone, allowing the burner to achieve stable ignition, efficient combustion and low emissions at a specified flow rate (USgph) and spray angle (degrees).

How does a 14 USgph oil nozzle work in a burner?

Fuel oil is pumped at 7–14 bar (typical domestic/commercial pressure-jet range) through a sintered filter, into a swirl chamber, and out through a calibrated orifice. The swirl imparts rotation, breaking the oil into droplets that mix with combustion air at the burner head.

At 14 USgph the nozzle is firmly in commercial/light-industrial territory — suitable for medium steam or hot-water boilers, large commercial kitchen steamers, and industrial process heaters. In Singapore this class of nozzle is common in F&B plants, pharmaceutical steam-raising, and marine/offshore auxiliary boilers.

Which spray angle and cone type should you choose?

Spray angle controls flame shape relative to the combustion chamber; cone type controls fuel distribution within the spray. Getting either wrong causes impingement, smoke, or unstable flame.

• 45° solid cone (S): narrow, concentrated flame — suits long, narrow combustion chambers. Example: Jetoil 14.00 45° S.
• 60° hollow cone (H): wider, hollow spray — suits short, wide chambers and boiler applications. Example: DELAVAN Type A 60° hollow-cone.
• 80°: very wide flame — short, wide fireboxes; check OEM limits.
• 30°: very narrow — long flame tubes only.

Specification comparison: 14 USgph-class and adjacent nozzles in stock

Step up the ladder when your burner OEM specifies a higher firing rate or when commissioning shows the flame is too short for the chamber. Step down when smoke or impingement appears at low fire. Always confirm the nozzle body marking matches the OEM datasheet before installation.

Selection criteria for Singapore buyers

1. Flow rate (USgph): match the burner OEM's rated firing rate — do not upsize to 'improve' output; it causes smoke and wasted fuel.
2. Spray angle: match the combustion chamber geometry (45° narrow, 60° standard, 80° wide).
3. Cone type: solid (S) for concentrated flame, hollow (H) for boiler and wider chambers.
4. Fuel compatibility: confirm the nozzle is rated for your fuel (kerosene, #2 diesel, bio-blends) — bio-blends may need OEM approval.
5. Environment: Singapore's humid tropical climate accelerates corrosion on brass nozzle bodies — store spares sealed and dry, and specify stainless or coated bodies where available.
6. Compliance: oil-fired installations fall under EMA licensing and WSH requirements; confirm your burner service provider holds the relevant permits.
7. Duty cycle: continuous industrial duty benefits from scheduled nozzle replacement (typically every 1,500–2,000 firing hours) rather than cleaning.

Types and applications in Singapore

Pressure-jet nozzles dominate Singapore's oil-fired installations. Common applications include:

• F&B plants: steam boilers and direct-fired process heaters.
• Pharmaceutical: clean-steam generation and thermal fluid heaters.
• Marine/offshore: auxiliary boilers and inert-gas generators — often 14–22 USgph class.
• Precision manufacturing: heat-treatment furnaces and ovens.
• Commercial buildings: standby diesel-fired boilers.

For very small duties (kitchen ranges, small boilers), lower-flow nozzles such as Jetoil 0.55 60° H or CBM Fluidics 2.75 60° SF are more appropriate.

Frequently asked questions

Q: What does '14kg.' mean on a 64 F 4007 oil nozzle?
A: The '14kg.' suffix is a trade pack/shipping weight class, not the flow rating. The flow rating is the USgph figure — for this class, approximately 14 USgph. Always confirm the USgph and spray angle on the nozzle body or OEM datasheet before ordering.

Q: Can I substitute a Jetoil 14.00 45° S for a 64 F 4007?
A: Only if your burner OEM datasheet specifies 14 USgph, 45° spray angle and solid cone. Substituting a different angle or cone type changes flame shape and can cause smoke, impingement or unstable ignition. Confirm with the OEM data first.

Q: How often should oil nozzles be replaced in Singapore's climate?
A: Typically every 1,500–2,000 firing hours, or annually for standby boilers. Singapore's humidity accelerates corrosion on stored spares — keep replacements sealed and dry, and replace rather than clean for reliable atomisation.

Q: What is the lead time for oil nozzles from 3G Electric in Singapore?
A: In-stock items typically ship same or next business day from Singapore stock. Non-stock items are quoted with lead time at enquiry. Contact us with your burner model and required USgph/angle for a firm quote.

Q: Do I need EMA or WSH approval to change an oil nozzle?
A: Oil-fired installations fall under EMA licensing and WSH requirements. Nozzle replacement itself is a maintenance task, but the burner must remain compliant — engage a qualified burner service provider and confirm permits with the relevant authority.
