Description

The Delavan 2.75 GPH 90° Type B Solid Cone Fuel Nozzle (distinguished by its blue protective cap) is a professional-grade heating and combustion component. It serves as a critical replacement part for the burner assemblies of high-output hot water pressure washers, large industrial boilers, and commercial oil furnaces, where it atomizes fuel to ensure highly efficient, clean, and stable heat generation.

With a high 2.75 GPH flow rate and a wide 90° spray angle, this nozzle is engineered to deliver high thermal output into wide, short, or compact combustion chambers.

Key Features

• Type B Solid Cone Pattern: Distributes atomized fuel droplets evenly throughout the entire spray cone. This uniform distribution ensures smooth ignition, stable flame geometry, and highly efficient heat transfer while minimizing soot and carbon buildup.

• Wide 90° Spray Angle: Provides a shorter, wider flame profile than narrower angles (like 60° or 80°), making it ideal for compact, shallow, or round heating coils and combustion areas.

• Premium Bi-Metal Construction: Engineered with a heavy-duty brass body for rapid heat dissipation (which prevents fuel varnishing and residue clogs) and paired with a precision-machined stainless steel internal metering section for maximum wear resistance.

• Integrated Sintered Filter: Equipped with a built-in mesh strainer at the base of the nozzle body to capture microscopic sediment, rust, and fuel impurities before they can reach the orifice, maintaining an uninterrupted flame profile.

• Color-Coded Blue Cap: Standardized color coding by Delavan indicates a “Type B Solid Cone” nozzle configuration, allowing technicians to quickly identify the correct pattern type during routine maintenance.

Common Applications

• Heavy-Duty Hot Water Pressure Washers: Utilized in high-capacity industrial pressure washers (such as units from Landa, Hotsy, Karcher, or Hydro Tek) that require a wide, high-volume burner configuration to rapidly heat high-GPM water flows for heavy grease and oil removal.

• Commercial Oil Burners & Furnaces: Installed in large facility heating systems running on standard heating oils, #1 diesel, #2 diesel, or kerosene.

• Industrial Boilers & Water Heaters: Used in agricultural, automotive, and industrial facility heaters requiring a reliable, high-output, wide-angle fuel atomization pattern.
