Description

The Delavan 2.75 GPH 80° Type B Solid Cone Fuel Nozzle (identified by its blue protective cap) is a professional-grade, high-capacity heating and combustion component. It serves as a critical replacement part for the burner assemblies of high-output hot water pressure washers, commercial boilers, and large 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 standard 80° spray angle, this nozzle is engineered to deliver substantial thermal energy into mid-to-large sized 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.

• 80° Spray Angle: Provides a balanced, standard-width flame profile that matches the internal geometry of medium-to-large heating coils and combustion chambers, preventing the flame from directly impinging on the chamber walls.

• Premium Bi-Metal Construction: Features a heavy-duty brass body for rapid heat dissipation (preventing fuel varnishing and residue buildup) combined 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 part during routine maintenance.
