Delavan Oil burner nozzles 00500-90B7

The Delavan 00500-90B7 is an oil burner nozzle with a capacity of 5 gallons per hour and a spray angle of 90 degrees. It features a B spray pattern, which is a solid-cone type that distributes droplets uniformly across the pattern. This nozzle is designed for use in burners to atomize fuel efficiently, promoting complete combustion and reducing emissions. It is particularly suited for larger burners, providing smooth ignition and efficient operation.

When selecting a replacement oil nozzle, ensure the capacity, spray angle, and spray pattern match the original specifications. The nozzle must be compatible with the burner's fuel pump pressure and flow requirements. Installation involves removing the old nozzle and installing the new one with the correct torque, ensuring the spray pattern is oriented properly. Always verify the nozzle's specifications against the burner's manual before ordering.

Oil nozzles can fail due to clogging from debris or carbon buildup, leading to poor atomization and incomplete combustion. Symptoms include soot formation, reduced burner efficiency, or difficulty igniting. A worn or damaged nozzle may cause uneven flame patterns or excessive fuel consumption. Regular inspection and cleaning or replacement of the nozzle can prevent these issues.
