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, consistent combustion performance, and controlled flame shape 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 45° spray angle are specified
