Delavan Oil burner nozzle 00200-45W1

The Delavan 00200-45W1 is an oil burner nozzle with a capacity of 2 gallons per hour and a spray angle of 45 degrees. It is a type W 'all purpose' nozzle, which is neither truly hollow nor solid. This nozzle is designed to evenly distribute fuel within a burner to form an optimal air-fuel mixture for efficient combustion. It is compatible with flow rates ranging from 0.40 to 8.00 gph, with lower flow rates tending to be more hollow.

When selecting a replacement oil burner nozzle of this type, ensure the capacity (in gallons per hour) and spray angle match the burner's requirements. The nozzle type (e.g., solid, hollow, or all-purpose) must also be compatible with the burner's air pattern. Nozzles are typically threaded and installed by screwing them into the burner's nozzle holder; verify the thread size and sealing method before installation.

Common failure modes for oil burner nozzles include clogging due to dirt or debris, which can cause uneven flame, soot buildup, or difficulty igniting. A worn or damaged nozzle may result in poor atomization, leading to incomplete combustion, increased fuel consumption, or a smoky exhaust. If the burner exhibits these issues, inspect the nozzle for blockages or wear and replace it if necessary.
