Description

The Delavan 2.25 GPH 80° Type A Hollow Cone Fuel Nozzle (identified by its red protective cap) is a professional-grade heating and combustion component. It serves as a critical replacement part for the burner assemblies of hot water pressure washers, commercial boilers, and oil furnaces, where it atomizes fuel to ensure clean, efficient, and stable heat generation.

With a 2.25 GPH flow rate and an 80° spray angle, this nozzle is engineered for medium-to-high capacity heating coils that utilize a hollow cone flame profile to match specific combustion chamber shapes.

Key Features

• Type A Hollow Cone Pattern: Distributes atomized fuel droplets primarily around the outside of the spray cone, leaving a hollow center. This configuration is ideal for specific burner air patterns, offering smooth ignition, excellent flame stability, and reduced smoke or soot production.

• 80° Spray Angle: Provides a balanced flame profile that optimizes heat distribution within medium-sized combustion chambers and heating coils, ensuring efficient heat transfer to the water or air.

• 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 a consistent flame profile.

• Color-Coded Red Cap: Standardized color coding by Delavan indicates a “Type A Hollow Cone” nozzle configuration, allowing technicians to quickly identify the correct part during routine maintenance.
