Spray patterns - Monarch Nozzles

Industrial and Residential Oil Nozzles, Oil Burner Nozzles, Spray Nozzles, Water Nozzles, Burner Spares and Burner Nozzle in India

Monarch industrial and domestic oil burner nozzles are available in a variety of spray patterns, spray angels and capacities.

Monarch Nozzle "R" spray patterns


Monarch Nozzle "NS" spray patterns


Monarch Nozzle "AR" spray patterns


Monarch Nozzle "PLP" spray patterns


Monarch Nozzle "PL" spray patterns


Monarch Nozzle "HV" spray patterns


Monarch Nozzle "HO" spray patterns



The spray patterns (i.e. hollow cone or solid cone) described below refer to tests carried out with a 60 nozzle at a 75 mm distance from the orifice. Nozzles with spray angles of 60 or less, and with low flows in particular, the empty section of a hollow cone becomes smaller. The difference between a hollow cone and solid cone nearly disappears at this point.


Spray Patterns include: R - Solid Cone, NS - Hollow Cone, AR - Special Solid Cone, CC - Constant Flow Rate , PLP - Semi-Solid PL - Hollow, HV - Narrow Spray Angle, HO - Heavy Oil Nozzles


Solid Cone "R" Series: .40 to 3.50 USGPH
This is the series supplied regularly unless specified otherwise. It is a good nozzle suitable for most burners. Atomization of the oil is not as fine as with the "NS" series.

Hollow Cone "NS" Series: .50 to 2.00 USGPH
This Series works best on many burners due to its exceptionally fine atomization. It produces a quiet, stable flame and is widely used on 80 and 90 flame retention burners.

Special Solid Cone "AR" Series: .50 to 3.50 USGPH
This series has become widely used due to its success in obtaining quiet combustion in flame retention head burners. Traditionally, a "cure-all" replacement nozzle, it now is increasingly specified on original equipment.

Semi-Solid Cone "PLP" Series: 2.25 to 100.00 USGPH
The standard nozzle for larger capacities. Fine atomization and "solid" spray pattern up to approximately 3.50 USGPH, gradually becoming more "hollow" in the larger sizes.

Hollow Cone "PL" Series: 2.25 to 50.00 USGPH
This series represents an extension of the "NS" type spray pattern for larger capacity sizes. Spray is not as finely atomized as the "PLP" series, but produces the best results in equipment specifying hollow cone nozzles.

Narrow Spray Angle "HV" Series: 1.65 to 60.00 USGPH
Used mostly for Semi-Industrial or Scotch Marine applications where narrow spray angle and high spray velocity is essential, and some combustion noise is not objectionable.

Heavy Oil Nozzle Series: 1.25 to 100.00 USGPH
Designed for use on 70 SSU (approx. 13 centistokes) viscosity oil at operating pressures ranging from 200-450 PSIG (13.8 to 31 bar). Write for special data sheet.



Monarch Nozzle | Spray Angles and Capacities

MONARCH developed the first porous metal Oil Burner Nozzle Filter to provide highly efficient filtration with a one piece construction. These Filters (40 to 60 microns) are supplied as standard up tthrough 1.00 USGPH on all series, unless Mesh Strainers (200 mesh/approx. 70 microns) are requested.

1.10 USGPH to 10.50 USGPH nozzles are fitted with 120 mesh (approx. 120 microns) Monel screen strainers. Mesh strainers may be used with higher GPH nozzles, up to a maximum of 30.00 USGPH, if ordered separately.

Nozzles are available in sizes from .40 to 100.00 USGPH, at 100 PSI (6.895 bar) for No. 2 fuel oil. Field tests may vary from the nominal rating due to oil viscosity (the higher the viscosity, the greater the nozzle flow and vice versa). When using No. 2 fuel oil within normal operating temperature range, the flow changes approximately 1% for each SSU change in viscosity.

MONARCH nozzles are tested at nominal pressures of 7 to 10 bar, with test oil, similar to No. 2 fuel oil, 34 to 36 SSU viscosity at 100 F, gravity 32 to 38 A.P.I. at 60 F and test temperatures 75 to 80 F (3.36 to 3.44 mm2/s at 20C, and a density of 0.840). The recommended operating pressures for nozzles used with domestic fuel oil and kerosene are from e to 25 bar. (Please consult us for higher pressures).For higher viscosity fluids, possible operating pressures range from 10 to 14 bar. However, this will result in a considerable reduction of spray angles, unless specially designed nozzles are used (see HO nozzles).


The "HO" nozzle is to be used on higher viscosity oils at elevated operating pressures. The nozzle nominal flow rate is 100 PSIG (6.895 bar) for No. 2 fuel oil and are available in capacities sizes from 1.00 to 100.00 USGPH.

Monarch Nozzle "NO DRIP" - Strainer Check Valve

Prevents nozzle after-drip which fouls burner air mixing rings and leads to poor combustion. Fits directly onto F80 nozzles in place of standard strainers. When an oil burner shuts down, pressure remains in the oil line. This forces oil through the nozzle. This oil drips onto the air mixing ring causing coking, reduced combustion efficiency, higher smoke and sooting.

After-drip may also occur whenair bubbles trapped in the oil line expand andcontract from pressure, or from expansion.Becausecheck valve requires 35 psi to open, pump pressuremust be set 35 psi higher to assure good atomizationand flow rate. Equipped with 120 mesh strainer.Restriction may occur on nozzles rated over17.5 GPH.
