Velocity Boiler Works (Crown) 13-142 Nozzle
The Velocity Boiler Works (Crown) 13-142 Nozzle is a high-precision Delavan 0.75/80A oil burner nozzle designed for service professionals requiring exact fuel atomization in residential and light commercial oil-burning appliances. This Type A hollow cone nozzle delivers a flow rate of 0.75 GPH at 100 PSI with an 80-degree spray angle, making it ideal for flame retention burners and combustion chambers where a stable, low-noise flame is required. Constructed with a brass body for rapid heat transfer and a stainless steel orifice disc, this part minimizes the risk of varnish and oil residue buildup that leads to common ignition failures. The sintered filter provides maximum protection against internal plugging, ensuring consistent delivery to the burner head. This nozzle is a direct OEM replacement part for Crown and Velocity boiler systems, engineered to maintain peak combustion efficiency and reduce emissions by concentrating droplet distribution on the periphery of the spray cone.
Key Benefits- Precise Atomization: The 0.75 GPH 80-degree A nozzle ensures optimal fuel-air mixing for efficient heat transfer and reduced soot.
- Hollow Cone Spray Pattern: Designed specifically for burners with a hollow air pattern, providing better ignition and a quieter flame.
- Heavy-Duty Construction: Features a bi-metal design with a brass body and stainless steel metering parts for thermal stability and wear resistance.
- Anti-Plug Design: Includes a shorter tangential slot and sintered filter to mitigate site-fuel contaminants.
- Wide Compatibility: Standard Velocity Boiler Works 13-142 part number simplifies cross-referencing for field repairs.
Is the 13-142 nozzle compatible with different oil pressures?
Yes, while rated at 0.75 GPH at 100 PSI, this nozzle can be utilized in systems with varying pump pressures; however, tech professionals should consult the manufacturer’s flow chart to ensure the BTU input remains within the boiler's rated specifications.
Why is a Type A hollow cone used instead of a Solid Type B?
Hollow cone nozzles like the Delavan .75 80A are typically preferred for smaller oil burners (firing under 1.00 GPH) and those with specific air patterns to achieve more stable combustion and easier ignition compared to solid patterns in the same flow range.
When should this nozzle be replaced?
For peak efficiency and to prevent emergency service calls, the nozzle should be replaced during every annual preventive maintenance cycle to counteract the natural wear of the orifice and filter saturation.
