Hago 2.50 45° Oil Burner Nozzle

Hago 2.50 45° Industrial & Marine Oil Burner Nozzle

The Hago 2.50 45° Oil Burner Nozzle is an engineered pressure-atomizing nozzle designed for heavy-duty industrial combustion systems, marine auxiliary boilers, thermal fluid heaters, and commercial forced-draft burners. Engineered to calibrate a precise volumetric flow rate of 2.50 US Gallons per Hour (GPH) at a reference atomization pressure of 100 PSI (7.0 bar), this nozzle projects a uniform 45° conical spray pattern for optimal fuel-air mixing, soot-free combustion, and high thermal efficiency.

Technical Specifications

Key Features

1. Precision-Metered Flow Stability: Delivers calibrated 2.50 GPH throughput with ±5% tolerance at standard 100 PSI rating, maximizing burner stoichiometric balance.
2. High-Integrity AISI 416 Stainless Core: Hardened orifice disc and swirl chamber resist micro-abrasions from high-velocity distillate fuels and heavy fuel blends.
3. 120-Mesh Monel/Stainless Filtration: Integral high-surface-area filtration core prevents slot clogs without causing input-side pressure drops.
4. Controlled Droplet Size Distribution: Creates uniform micro-droplets ranging from 0.0002″ to 0.010″ for instantaneous ignition, reduced carbon buildup, and low NOx/CO emissions.
5. High-Torque Sealing Interface: Hexagonal flat geometry enables secure installation into brass or steel adapter manifolds up to 310 in-lbs (35 Nm).

Frequently Asked Questions

What does the 2.50 45° designation mean on this Hago nozzle?

The “2.50” indicates a calibrated fuel delivery rate of 2.50 US Gallons per Hour (GPH) when operated at standard pump pressure of 100 PSI. The “45°” defines the included angle of the atomized fuel spray cone entering the combustion chamber.

What is the difference between Hago Solid (B), Semi-Solid (SS), and Hollow (H) spray patterns in 45°?

A Solid Cone (Type B) distributes fuel droplets evenly across the entire circular cone volume, ideal for larger burners with uniform air distribution. A Hollow Cone (Type H) concentrates droplets around the outer rim of the cone, designed for low-flow rates or hollow air patterns. Semi-Solid (SS) is a universal hybrid pattern optimized where exact chamber air patterns vary.

How often should oil burner nozzles be replaced in commercial or marine service?

Nozzles are precision wear parts subject to high heat and erosion. In continuous industrial or marine auxiliary boiler duty, replace nozzles annually or every 1,500 to 2,000 operating hours to prevent flame distortion, elevated soot generation, and fuel waste.

Can I run heavy marine fuels or waste oil through this nozzle?

This nozzle is calibrated for distillate fuel oils (No.2 fuel oil, Marine Gas Oil, Diesel). Heavy fuel oils (HFO) or blended fuels require preheating to reduce viscosity below 5 cSt and high-pressure atomization, otherwise atomization quality drops significantly.
