POROUS
BRONZE FILTERS
MONARCH developed the first porous metal Oil Burner Nozzle Filter in order to
provide highly efficient, in-depth filtration with one piece construction. Fine Filters
(40 to 60 microns) are supplied as standard up to and including 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 as standard with 120 mesh/approx. 120 microns
Monel screen strainers. Strainers may be used with larger sizes to a maximum of 30.00
USGPH but must be ordered separately.
Nozzles up to and including 1.00
USGPH are also available with 200 mesh Monel screen strainers as an alternative to the
recommended porous bronze filter.
CAPACITY
SIZES
Available in sizes from .40 to 100.00 USGPH at 100 PSI (6.895 bar) on No. 2 fuel
oil. Field tests may show more or less flow than the nominal rating as the flow varies
with the 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
The MONARCH MTD-92 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 temperature 75 to 80° F (3.36 to 3.44 mm2/s at
20°C, and a density of 0.840). The recommended operating pressures for MTD-92 nozzles
used with the 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. This, however, will result in a considerable reduction of spray angles, unless
specially designed nozzles are used (see MTD-HO nozzles).
MTD-HO
NOZZLES FOR LIGHT, MEDIUM AND HEAVY FUEL OIL
This is a specially designed version of the MTD-92 nozzle, particularly suitable for
domestic and heavy fuel combustion with a higher viscosity level up to 0.5 est. Two
versions are offered with same dimensions and thread as MTD-92.
The "HO" is offered to
meet the requirements for nozzles to be used on higher viscosity oils at elevated
operating pressures. These nozzles (as with all MONARCH MTD-92 nozzles)
are stamped with their nominal flow rate at 100 PSIG (6.895 bar) on No. 2 fuel oil and are
available in capacity sizes from 1.00 through 100.00 USGPH.
HO-200 PSI
(14 bar)
When regular light oil nozzles are used on more viscous oil, their sprays tend to
"flutter", they produce a narrower spray angle and often develop 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, the HO nozzles are also available (at higher cost) tested for
spray angle and spray quality at 430 PSIG (30 bar) on 70 SSU operating viscosity oil. In
addition to the regular stamping, these nozzles are stamped 430 to distinguish them from
standard "HO". nozzles, as standard nozzles would not be satisfactory for use at
such high operating pressures. The special additional testing is necessary to be sure that
no streaks, voids or flutter appear in the spray at these pressures that would not appear
at 200 PSIG. The spray angle stamped on the nozzle is the nominal Spray Angle at 430 PSIG
operating pressure.Note that 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, and sizes of 50.00 USGPH and up are available only in 60° and
80°. 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.
