Description

The Delavan 2.50 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 vital replacement part for the burner assemblies of hot water pressure washers, industrial boilers, and commercial oil furnaces, where it atomizes fuel to ensure highly efficient, clean, and stable heat generation.

With a high 2.50 GPH flow rate and a wide 90° spray angle, this nozzle is engineered to deliver high thermal output into short, wide, 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 the perfect choice 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.
