Delavan Oil nozzles 00850-60B7

The Delavan 00850-60B7 is an oil nozzle designed for use in burners, playing a key role in fuel combustion. It delivers a fuel dose of 8.5 gallons per hour (GPH) with a spray angle of 60 degrees and a spray pattern type B. This nozzle adjusts the fuel dose to maintain an optimal fuel-air ratio, which enhances thermal efficiency and reduces emissions. It also atomizes fuel into fine droplets for uniform mixing with air, ensuring efficient combustion and proper flame formation. The nozzle is identified by article number 345.892.275 and is suitable for heating systems and other devices requiring precise fuel delivery.

When selecting a replacement oil nozzle of this type, ensure the capacity (in GPH), spray angle, and spray pattern match the burner's requirements. The nozzle must be compatible with the burner's fuel pump pressure and flow rate. Installation involves removing the old nozzle and installing the new one with the correct torque, ensuring the O-ring or gasket is in good condition. Always verify the nozzle's specifications against the burner's manual before ordering.

Common failures of oil nozzles include clogging due to dirt or debris, which can cause uneven flame, soot formation, or incomplete combustion. A worn or damaged nozzle may lead to improper atomization, resulting in poor ignition, flame instability, or increased emissions. If the burner fails to start, produces a smoky flame, or has reduced heating efficiency, inspect the nozzle for blockages or wear and replace it if necessary.
