Product Description
The PrimeFire 100 provides flexibility, extended fuel firing
capability, increased melter efficiency, improved refractory
life, and reduced melting cost. The Primefire 100 oxygen-
fuel burner produces a conventional shape flame and the
adjustable control on the burner allows variation in flame
coverage to suit melter size and temperature profile.
To fire oil on a dual fuel setup, the plug at the rear of the
gas inlet (Figure 1.1) is removed and the oil/atomizing
assembly (Figure 1.3) is installed.
For oil firing only, the gas inlet assembly is not needed,
and the oil/atomizing assembly is installed in its place.

Important notices which help provide safe burner
operation will be found in this section. To avoid personal
injury and damage to the property or facility, the following
warnings must be observed. All involved personnel should
read this entire manual carefully before attempting to start
or operate this system. If any part of the information in this
manual is not understood, contact Eclipse before
continuing.
Safety Warnings
■The burners, described herein, are designed to mix
fuel with air and burn the resulting mixture. All fuel
burning devices are capable of producing fires and
explosions if improperly applied, installed,
adjusted, controlled or maintained.
■Do not bypass any safety feature; fire or explosion
could result.
■Never try to light a burner if it shows signs of
damage or malfunction
■Exposure to liquid oxygen or cold oxygen gas can
cause severe burn-like injuries.
The temperature of the liquid oxygen in the storage vessel
is -279°F (-173°C). Contact with liquid or cold gaseous
oxygen will freeze living tissue within seconds. Typically,
the hazard exists only within the boundaries of the storage
area, specifically between the storage vessel and the
vaporizers. The oxygen pipeline downstream of the
storage area contains oxygen gas at ambient
temperatures. Interlocks at the storage area prevent liquid
or cold gas from entering the oxygen pipeline.
When working near cryogenic liquids or cold gas
pipelines, wear loose-fitting gloves, e.g. leather, and
safety glasses or goggles.
■Pressurized gas lines can damage equipment and
injure personnel.
The oxygen pipelines can contain pressures up to 200
PSIG. Exercise care when working on or around these
pressurized lines. Ensure the pressures have been
vented before breaking any connection. Tag out a line
before performing any work on it. Wear a face shield when
working on pressurized lines.
■High concentrations of oxygen rapidly accelerate
combustion of most materials and could damage
equipment and injure personnel.
Oxygen concentrations in excess of 25% significantly
increase the fire hazard exposure to personnel and
equipment. Those materials which burn in air will burn
more violently and sometimes explosively in oxygen.
Reducing the hazard requires meeting stringent oxygen
guidelines for specifying equipment, materials of
construction, and system cleanliness. Only those
personnel familiar with the hazards of oxygen and safe
practices for oxygen systems should be permitted to
operate and maintain the system.
■The burner and duct sections are likely to have
HOT surfaces. Always wear the appropriate
protective equipment when approaching the
burner
■Open all valves slowly.
Since many materials will burn in the presence of oxygen,
the temperature rise caused by adiabatic compression of
the oxygen gas could result in igniting pipeline materials.
Rapid filling of an oxygen line from one pressure level to
another will result in a temperature increase of the gas
within the line due to adiabatic compression. Lines should
thus be pressurized slowly to minimize this temperature
rise. To avoid adiabatic compression, slowly open all
valves until pressures have equalized across the valve;
then open the valve fully. Ignition of flammable materials
in the pipeline, if present, could occur if the line were
fabricated of ferrous material.

■Use only equipment specifically designed for
oxygen service.
The equipment installed in the flow control and oxygen
distribution system has been carefully selected to meet
strict oxygen compatibility and velocity requirements.
Inappropriate materials of construction increase the
danger of ignition of pipelines and controls. Sizing is just
as important to ensure all velocity restrictions for oxygen
are met. Do not substitute components or equipment
without written approval from Eclipse, Inc.
■Maintain oxygen cleanliness at all times.
All equipment and piping in contact with oxygen must be
cleaned to conform to specifications outlined in CGA
Pamphlet G-4.1. Failure to clean components and piping
increases the danger of ignition and fire. Note that even
the cleaning solvent must be removed completely before
the equipment can be placed into service. Maintain
cleanliness during assembly, installation, and repair.
■No open flames, smoking, or sparks are permitted
near oxygen equipment.
Since many materials will burn in oxygen, the best method
in preventing fires is to eliminate sources of ignition.
Where oxygen control equipment is being used or where
concentrations of oxygen are greater than 25%, avoid
open flames, sparks, or sources of heat. Never weld on a
pressurized oxygen line. Make sure signs are posted
warning personnel that oxygen is in use.
■Do not substitute oxygen for compressed air.
Substituting oxygen for compressed air is dangerous.
Chances are the instrument air equipment is neither
compatible with oxygen, nor cleaned for oxygen service.
Oxygen used to clean off equipment or clothing could
come in contact with a source of ignition (spark, flames, or
other) and ignite. In some cases, the elevated oxygen
levels could linger even after the source has been shut off.
■This manual provides information regarding the
use of these burners for their specific design
purpose. Do not deviate from any instructions or
application limits described herein without written
approval from Eclipse
Capabilities
Only qualified personnel, with sufficient mechanical
aptitude and experience with combustion equipment,
should adjust, maintain or troubleshoot any mechanical or
electrical part of this system.
Operator Training
The best safety precaution is an alert and trained
operator. Train new operators thoroughly and have them
demonstrate an adequate understanding of the
equipment and its operation. A regular retraining schedule
should be administered to ensure operators maintain a
high degree of proficiency.
Replacement Parts
Order replacement parts from Eclipse only. All Eclipse
approved valves or switches should carry UL, FM, CSA,
CGA and/or CE approval where applicable

Installation
7PrimeFire 100, Oil, Operating Instructions, Edition 9.12
Installing the Mounting Bracket
Use this procedure to install the mounting hardware in
preparation for installing the burner.
NOTE: If possible, do this work before (or in the very early
stages of) furnace heat-up.
1. Install the burner mounting bracket (21) with gasket
on the precombustor using four T-bolts, washers, and
nuts (23). See Figure 3.1.
The T-bolts are only intended to secure the mounting
plate to the precombustor. The mounting plate must
be supported by the bolt assembly before installing
the burner.
2. Support the burner mounting bracket with a jack
screw (A) and nuts (B). Make sure the horizontal plate
is level. See Figure 3.2.
3. Briefly install the burner and flexible hoses into the
precombustor to make sure the supply piping will
permit easy burner installation.
Figure 3.1 PrimeFire 100 exterior
Figure 3.2 PrimeFire 100 interior
NOTE: Whenever the burner is not in use, plug the burner
block with a high temperature fiber wool rolled blanket.
Adjusting the Burner Tip
The atomizing orifice in the burner oil tip is adjustable. Use
this procedure to adjust the burner tip.
Figure 3.3
1. Unscrew the locking collar. See Figure 3.3 above.
2. Rotate the oil boss to open or close the area of the
atomizing orifice.
For startup, open the atomizing area by retracting the
oil tip (by rotating the oil boss) 1.5 mm (0.06 inch)
back.

To set the initial oil tip position, set the oil tip flush with
the atomizing tip, then rotate the oil tube two full turns
back from flush. Two turns = 1.5 mm = 0.06 inch.
■Never operate this burner with the atomizing
oxygen orifice completely closed; this will cause it
to inject oil into the furnace without atomization,
which will cause a severe safety-related incident.
Notes on Burner Cooling
Use the following guidelines to make sure that the cooling
requirements for the burner are in place before installing
the burner.
■Combustion and atomizing oxygen cool the burner
and block, as well as supporting combustion. The
burner oxygen nozzles and fuel oil atomizing
assembly are made of a heat-resistant steel alloy,
but they can still be damaged if they are exposed
to furnace radiation without cooling oxygen flows
in the form of combustion and atomizing oxygen.
For oxy/oil firing, the fuel oil atomizing assembly is
extended well into the pre-combustor. It is roughly 63.5
mm (2.5 inches) back from the hot face of the pre-
combustor. At this location, the atomizing assembly must
have atomizing oxygen flow for cooling purposes at all
times. Otherwise, it could suffer extensive heat damage or
meltdown.
The flow should be 10—23 Nm3/h (320 to 800 SCFH).
The combustion oxygen flow of about 27 Nm3/h (1,000
SCFH) must also be maintained, to keep the pre-
combustor cool and free from furnace gases which could
deposit particulates/volatile matter on the precombustor
inner wall. In case of an emergency or power failure, pull
the entire burner body out to the pre-combustor opening
and plug the pre-combustor with a refractory plug or high-
temperature fiber wool blanket.
Before installing the burner, have the combustion oxygen,
atomizing oxygen, and the fuel oil supply lines ready and
pressurized, so that within a few minutes of the burner
being placed in the block, a combustion oxygen flow of
about 27 Nm3/h (1000 SCFH) and atomizing oxygen of 10
Nm3/h (320 SCFH) can be started to provide cooling. The
only action required to start the oxygen flow at this point
should be to open the ball shutoff valve closest to the
burner.
Installing the Burner
After the mounting hardware is installed and cooling
requirements are in place, use this procedure to install the
burner.
NOTE: Before installing the burner, make sure that all
steps to achieve minimum oxygen flow through the burner
can be completed within less than five minutes after
burner installation.
■If the burner is not level, premature failure of the
precombustor is possible
1. Clamp the burner to the mounting section using the
clamping mechanism on the burner. Do not over-
tighten the clamps. Use only enough pressure to
ensure a firm seal of the burner to the pre-
precombustor. Insert the safety pins through the
clamping mechanism to lock it in place.
2. Connect the combustion oxygen, atomizing oxygen,
and the fuel oil hoses to the burner.
3. If the oil purge system is supplied, set the purge/oil
switch to Purge.
4. Open the combustion oxygen shutoff valve closest to
the burner to begin flowing oxygen at a rate of about
27 Nm3/Hr (1000 SCFH) through the burner to
provide cooling.
5. Open the atomizing oxygen shutoff valve closest to
the burner to begin flowing oxygen at a rate of about
10 Nm3/Hr (320 SCFH) through the burner to provide
cooling.
■Make sure the furnace is at a minimal temperature
for auto-ignition, 800°C (1472°F).
Firing the Burner with Oil
After installing the burner, use this procedure to fire the
burner using fuel oil.
NOTE: When firing oil, the oil tube tip must be retracted
into the atomizing nozzle 0.03" at a minimum. Issues may
occur if the oil tube is mounted in the incorrect position.
NOTE: If heavy (#6) oil is used, the oil temperature should
be adjusted to maintain an oil viscosity of about 20
centistokes (between 90—110 SSU) at the burner. Higher
oil viscosities are desirable, short of the oil flashing or the
small amount of water found in heavy oil turning to steam.

Either of these occurences may cause unstable (pulsing)
burner performance.
1. Adjust the combustion oxygen flow to the lowest firing
range of the burner (approximately 2000 SCFH per
MMBtu of fuel input).
2. Adjust the atomizing oxygen pressure to 10 PSI for
light oil, 20 PSI for heavy oil.
3. Open the fuel oil shutoff valve and adjust the flow rate
to the minimum firing range of the burner.
NOTE: Observe the initial firing to ensure the flame is
centered in the precombustor and atomization is
sufficient.
4. After initial firing, combustion oxygen, atomizing
oxygen and fuel flows may be adjusted as desired.
When satisfactory atomizing oxygen flow is achieved,
the combustion oxygen can be adjusted to obtain the
total oxygen flow requirements for a given input
(approximately 2000 SCFH per MMBtu of fuel input).
NOTE: The exact ratio will vary depending on the calorific
value of the fuel and the actual percentage of oxygen into
the oxygen delivered.
Combustion oxygen velocity is typically set at the
maximum velocity position. After firing has been
established, combustion oxygen velocity can be adjusted
if necessary.
■Do not fire burner above or below capacity ranges.
This may cause the burner block to overheat.
Figure 3.4
Adjusting the Flame Shape
After initial firing, use this procedure to adjust the flame
shape.
1. Before attempting any flame shape adjustment with
the burner adjustment screw, loosen the locking bolt.
See Figure 3.2 above.
2. The burner nozzle can be adjusted to 51 mm (2
inches) in relation to the front end flange. To move the
nozzle forward, turn the adjustment screw (item 60)
clockwise. Each increment on the position rod
represents 3 mm (1/8 inch) of nozzle travel.
NOTE: Typically, the nozzle is set to the Full In (maximum
velocity) position to operate the burner when firing oil. If
the position is set too far back, combustion may start
quickly and cause overheating of the block.
3. Tighten the locking bolt after the desired flame shape
adjustment has been made.
Shutting Down and Removing the Burner
If a burner needs to be shut down temporarily, or for an
extended period, use the following procedure.
If a burner is to be taken offline temporarily and not
removed from the burner block, combustion and
atomizing must be supplied to the burner for cooling
purposes. If both the combustion and atomizing oxygen to
the burner are interrupted for more than 10 minutes, the
burner must be removed from the precombustor.
If a burner is to be taken offline for an extended time, use
the following procedure.
1. If the purge system is provided, purge the oil from the
burner.
2. After the purge is complete, reduce atomizing oxygen,
combustion oxygen, and fuel oil flow control valves to
minimum.
3. Shut off the combustion oxygen, atomizing oxygen,
and fuel oil shutoff valves closest to the burner.
4. Release the burner clamps from the mounting
bracket. Remove the burner from the precombustor
and mounting bracket.
5. Disconnect the combustion oxygen, atomizing
oxygen, and fuel oil lines from the burner inlet.
6. Place a high-temperature fiber wool rolled blanket in
the cavity of the precombustor to prevent hot furnace
gases from escaping through the block.

7. If the burner is not being used for an extended time,
plug or cover the block opening with mullite or a
bonded AZS block instead of fiber wool.
8. If the burner is to be left out of service, close all
service valves on the metering and control skid.
■Ensure that all lock-out and tag-out procedures are
in place according to your plant procedures.
NOTE: Whenever removing a burner from service, always
keep the oxygen-compatible components cleaned and
sealed. Hoses should be capped when not used. Burners
should be cleaned and stored in a sealed plastic bag.
Inspecting the Burner
Each shift should inspect the Primefire burners just as you
would inspect firing conditions in your present furnace.
Use these guidelines to inspect the burners, blocks, and
operation.
Recommended checks:
• Flame shape and appearance
• Burner block appearance
• Proper cooling effect on burner and block
• Combustion oxygen flow
• Atomizing oxygen flow and pressure
• Fuel oil flow and pressure
Obvious changes from the standard should be
investigated. If needed, fuel should be shut off with
combustion and atomizing oxygen set to a minimum while
the situation is investigated.
Maintaining the Burner
Under normal operating conditions, the Primefire oxy-oil
burner should need little attention. If you need to remove
and inspect a burner, use this procedure.
1. Follow the steps above under Burner Shutdown and
Removal.
2. The oxygen tip can be viewed and inspected. See
Figure 1.2 on page 4.
3. To remove the atomizing assembly:
a.Remove the ball lock pin.
b.Gently pull the atomizing assembly out of the
burner body.
3. The oil tip can be removed by loosening the oil boss
at the rear of the tube, then pulling the oil tube out.
4. To view and inspect the intermediate tip, remove the
roll pin from the burner adjustment screw and pull the
tube out of the burner body. See Figure 3.2
NOTE: The o-rings are used for sealing between the oil
and atomizing oxygen tubes, the intermediate and
atomizing oxygen tubes, and the intermediate and
combustion oxygen tubes. See Figure 1.1, 3.1 and 3.2.
Use only Eclipse supplied halocarbon grease on the o-
rings to ensure oxygen compatibility. Also make sure the
surfaces that mate with the o-rings are kept clean and are
not scratched. A damaged surface can cause a leak.
Cleaning the Burner Parts
After the burner is disassembled, use the following
procedure to clean the parts.
1. Using compressed air and cleaning solvent, clean the
oil tube tip.
Handle all tips carefully to prevent damage.
2. Wipe the oil tube clean.
3. Clean the atomizing oxygen tube with appropriate
oxygen cleaning solvents. Wipe the tube clean when
done.
4. Clean all oxygen-compatible components and wipe
clean when done; reassemble the burner by reversing
the disassembly instructions under Burner
Maintenance.
When reassembling the burner:
• Examine all o-rings and apply fresh halocarbon
grease.
• Use the centering lugs for the oil tube, atomizing
oxygen tube, and intermediate tube to ensure the
respective tube is in the proper centered location for
efficient mixing.
NOTE: Be careful not to damage the sealing surface on
the atomizing tube assembly. A damaged surface can
cause a leak.
• Verify the oil tip is in the correct position, and is
locked in position.
Always store the burner in a sealed plastic bag. This will
ensure that the burner is oxygen-compatible and ready to
fire.
