HO Spray Pattern (Heavy Oil)

Monarch HO (Heavy Oil) nozzles are designed for use with 70 SSU fuel oil at operating pressures ranging from 200 to 450 PSIG. The HO series covers a firing range of 1.25 to 100.00 USGPH and is optimized to deliver reliable atomization of higher‑viscosity oils under high‑pressure conditions. This design supports stable flame formation and consistent combustion performance in burners specifically engineered for heavy oil operation.

Applications

• Commercial and industrial heavy oil‑fired burners
• Boilers and furnaces operating on 70 SSU (≈13 cSt) fuel oil
• Systems designed for high‑pressure oil atomization
• Service replacement where Monarch HO spray pattern and 80° spray angle are specified
