The C-169-WA and C-170-WA Industrial Burner Nozzles are widely used in industrial combustion systems where compressed air is used to atomize fuel oil. These nozzles combine air and oil within a common swirl chamber, producing an exceptionally fine spray that ensures efficient fuel burning and improved combustion performance.

Designed for operation with atomizing air pressures up to 21 PSI, the nozzles provide reliable performance across a wide range of firing rates. Properly matched with high-velocity combustion air systems, they generate a rapidly rotating flame pattern that enhances fuel-air mixing and combustion efficiency.

The nozzles are suitable for both light and heavy fuel oils. For higher viscosity fuels, preheating is recommended to achieve optimal atomization and burner performance.

Manufactured from durable cold-rolled steel, the C-169-WA and C-170-WA nozzles are available in multiple capacities and spray angles to meet various industrial burner requirements.

Technical Description

The C-169-WA and C-170-WA nozzles utilize an air atomization principle where air and fuel enter a common swirl chamber through separate passages. The mixture is accelerated and discharged through the nozzle, producing a finely atomized spray pattern ready for combustion.

For optimum performance, oil pressure should remain at least 2 PSI higher than atomizing air pressure. Best atomization is typically achieved when oil pressure exceeds air pressure by 8–10 PSI.

The nozzle design supports excellent turndown capability, allowing burner operators to adjust firing rates while maintaining efficient combustion and stable flame characteristics.
