Delavan Oil burner nozzles 00040-80B4

The Delavan 00040-80B4 is an oil burner nozzle with a capacity of 0.4 gallons per hour (0.4 kg/h) and a spray angle of 80 degrees. It features a type B spray pattern, which produces a solid cone for even droplet distribution. This nozzle is designed for use in domestic and industrial high-pressure burners, where it atomizes fuel into fine droplets for efficient combustion. The SKU is 00040-80B4, and the article number is 345.892.301.

When selecting a replacement oil nozzle, ensure the capacity (in GPH), spray angle, and spray pattern type match the original specifications. The nozzle must be compatible with the burner's pressure range and fuel type. Installation involves removing the old nozzle, cleaning the mounting threads, and torquing the new nozzle to the manufacturer's recommended specification.

Common failure modes include clogging due to debris or carbon buildup, which can cause uneven flame, soot formation, or reduced heating efficiency. A worn or damaged nozzle may lead to poor atomization, resulting in incomplete combustion and increased fuel consumption. Regular inspection and cleaning of the nozzle and its filter can prevent these issues.
