21.50 80 PL - Monarch - Oil Nozzle - 12 Pack

21.50 80 PL – Monarch Oil Nozzle (12 Pack)

Monarch 21.50 80 PL oil nozzles are engineered for high‑capacity oil‑fired burners requiring accurate fuel delivery and a true hollow cone spray pattern. Manufactured to Monarch’s exacting standards, these nozzles are designed to perform reliably in commercial and industrial heating applications where burner specifications call for hollow cone atomization at elevated firing rates.

Technical Specifications

• Flow Rate: 21.50 GPH
• Spray Angle: 80°
• Spray Pattern: PL – Hollow Cone
• Rated Pressure: 100 PSI
• Manufacturer: Monarch Mfg. Works
• Pack Quantity: 12 nozzles

PL Spray Pattern (Hollow Cone)

Monarch PL (Hollow Cone) nozzles cover a firing range of 2.25 to 50.00 USGPH and represent an extension of Monarch’s NS‑type hollow cone spray pattern into larger capacity sizes. While atomization is not as fine as the PLP series, the PL design delivers optimal combustion performance in burners specifically engineered for hollow cone nozzles. This spray pattern supports proper flame shape, controlled flame expansion, and effective air/fuel mixing in high‑output systems.

Applications

• Commercial and industrial oil‑fired burners
• Boilers and furnaces requiring high GPH output
• Service replacement where Monarch PL spray pattern and 80° spray angle are specified
