Oil Burner Nozzle Types

Oil burner efficiency hinges on a nuanced understanding of the intricate components at play. Among these, the oil burner nozzle stands as a crucial player, responsible for atomizing oil within the combustion chamber. Here, we delve into the various types of oil burner nozzles, shedding light on their unique characteristics and applications to empower industry professionals with informed choices.

Hollow Cone Nozzles (Type A):

Suitability: Ideal for hollow air pattern burners and small burners firing at 1.0 gph and below.
Spray Pattern: Produces fine droplets outside the main spray cone, enhancing ignition and ensuring a stable flame.
Advantages: Offers stable spray angles and patterns, especially advantageous in fractional gallon nozzles under challenging conditions.

Solid Cone Nozzles (Type B):

Suitability: Appropriate for larger burners firing above 2.0 or 3.0 gph.
Spray Pattern: Distributes droplets uniformly throughout the pattern, becoming progressively hollow at high flow rates.
Usage: Provides smooth ignition, especially in burners with a heavy center air pattern or where extended fires are necessary.

Semi-Solid Nozzles (Type W):

Suitability: Suitable for rates between 0.40 and 8.0 gph, adaptable irrespective of burner air pattern.
Spray Pattern: Offers a balance between hollow and solid spray patterns, catering to a wide range of burner specifications.

Atomizing Nozzles:

Flow Rates: Available across a wide range, minimizing the need for specially calibrated nozzles.
Considerations: Select the smallest firing rate that adequately heats the system on the coldest day for optimal efficiency. Aim for a reasonable stack temperature to balance efficiency and load requirements.
