POROUS
BRONZE FILTERS
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.
MESH
STRAINERS
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.
CAPACITY
SIZES
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.
OPERATING
PRESSURES AND VISCOSITIES
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.
HO-200
PSI (14 bar)
When regular light oil nozzles are used on more viscous oil,
their sprays tend to "flutter", and produce a narrower
spray angle with streaks in the spray. Accordingly, the standard
"HO". nozzles are specially tested for spray quality
and rated for spray angle at a pressure of 200 PSIG (14 bar)
on 70 SSU (13 Centistoke) operating viscosity oil. This special
testing assures that the nozzles will perform properly under
heavy oil operating conditions. The spray angle stamped on the
nozzles is the nominal spray angle at 200 PSIG operating pressure.HO
- 30 PSI (30 bar)For high pressure operation, HO nozzles which
are tested for spray angle and spray quality at 430 PSIG (30
bar) on 70 SSU operating viscosity oil, are also available. The
additional testing is necessary to ensure that no streaks, voids
or flutter appear in the spray at these pressures. The spray
angle stamped on the nozzle is the nominal Spray Angle at 430
PSIG operating pressure.Note: the nominal flow rates stamped
on the nozzles are based on 100 PSIG using U.S. No.2 fuel oil,
subject to a flow tolerance of plus or minus 5%. Flow rates shown
at 300 PSIG on 70 SSU operating viscosity oil are from actual
tests. Flow rates at higher and lower pressures are predicted
from the 300 PSIG data. Actual flow rates may vary, depending
on exact operating conditions.Nozzles for operation at 200 PSIG
are available in 45°, 60° and 80° spray angles in
sizes of 2.25 USGPH up to, and including 45.00 USGPH, sizes of
50.00 USGPH nozzles, and up, are available only in 60° and
80° spray angles. Nozzles for operation at 430 PSIG are available
in 45°, 60° and 80° in sizes 1.00 USGPH up to and
including 45.00 USGPH. Sizes of 50.00 USGPH and up are available
only in 80°. Strainers are not included with nozzles but
120 mesh Monel Strainers may be ordered separately. Strainers
are specifically not recommended for use on sizes over 50.00
USGPH, as restriction may occur.
