3. Safety Guide
Only those who were trained and qualified person can follow the manual to operate or
adjust the combustion system. The fire was prohibited within a radius of 5 meters of the
combustion system. Flame, non–covered light sources or heat sources shall not be brought
to the combustion area unless it is related to the process. Welding in combustion control
area shall be approved to ensure the safety in the area and also preventive measures
should be taken into consideration.
Before starting, the operator must confirm whether the burner and gas pipeline are in
normal working condition, and there is no flammable substance around the burner. The
burner must be operated with fuel and oxygen or air. The ignition and operation of the
burner must be performed at the specified position. The burner has been correctly and
safely installed before ignition. The ignition of the burner needs to be performed after the

combustion chamber is purged. If it is ignited at a low temperature, it needs to be replaced
with 5 times the volume of the combustion chamber to avoid explosion.
However, it is not necessary to purge when the temperature is higher than 750°C. Air pipe
or gas pipe connected with burner should be tight enough with no leakage, also the
periodically check air or fuel nozzles of the burners to prevent to be blocked by dust, slag
or other materials.
ATTENTION：DANGER OF BEEN BURNT
When burner in operation, combustion is severe, so the burner must be fixed inposition.
Hoses or cables in area of the combustion system must be suitable for high temperature,
to prevent high temperature failure or cause safety accidents. Burners should be
periodically inspected and cleaned. Copper wire brush may be used, if necessary, to clean
burner head. The burner system should be checked twice a year for safety operation.
Burner commissioning shall take care of ignition position, minimum and maximum output
position. Following interlocks will cause emergency stop, including gas low pressure, high
pressure or low combustion air pressure, as well as emergency stop is trigged, the main
power is out, UV signal failure or kiln safety conditions (such as high temperature limit, flue
system opening, etc.) will cause the burner lockout. Users need to know the maintenance
interval recommended by the manufacturer and the interval specified by national laws,
whichever is shorter.

5.1 VFI84 Series Burner Operation Process
VFI84 series of burners are mounted in the exhaust duct and required the exhaust
stream to supply all of the oxygen needed for complete combustion. Because of
character of the process, they are well suited to applications require clean high rate of
destruction of volatile organic compounds, smoke and odors. Do not use choke rings or
other turbulence-inducingdevices in downstream combustion chambers—they may
cause erratic burner performance.

5.3 Pilot burner
VFI84 Series Burner has a separated pilot burner of maximum capacity 50kw.User need
to supply fresh combustion air for pilot burner, typically a small air blower or
compressed air need to apply to pilot burner. According to pilot burner's manual, 5 mbar
combustion air and 3 mbar gas pressure is necessary for pilot burner operation
continually. These pressure requirements satisfy combustion chamber with neutral
pressure, if oven chamber pressure exists, chamber pressure needs to be added to the
pressure value mentioned above. It should be noted that the depth of pilot burner

5.4 Combustion Air
Air passing through the burner for combustion must contain 13% or more oxygen.
Combustion air pressure difference between burner (shown as A and B in figure 1) should
be at the range of 2-8 mbar, optimum operation is obtained at 5-8 mbar. Profiling of the
process stream is required.
6. VFI84 Burner Operation Data
Follow parameters should be at specific range when VFI84 series burners are applicated
–Maximum exhaust temperature of upstream of burner: 600 °C
–Maximum exhaust temperature of downstream of burner: 900 °C
–Maximum hot exhaust pressure difference between burner: 8 mbar (A and B pressure
difference in figure 1)
–Minimum hot exhaust pressure difference between burner: 2 mbar (A and B pressure
difference in figure 1)
–Minimum exhaust oxygen content: 13%.
–When hot exhaust pressure drop of the burner is 5 mbar, the exhaust flue gas
turndown ratio can be about 2. The ratio increases when pressure drop gets higher.
–Maximum burner fuel turndown ratio will be 26 when the pressure drop between the
burner is 5 mbar
–Maximum ignition capacity:50 kw (with natural gas and fresh air)
–Maximum flame length:3 times length of the burner cone diameter.
–Flame supervision: UV scanner only
–NOXemission: typically, less than 3000 ppm.
–CO emission: less than 100 ppm if combustion chamber is 700 °C or hotter, and the
incoming fume stream contains at least 16% oxygen by volume

8. VFI84 Burner Installation
When installing this series of burners, the burner is fixed to the mounting hole of the
furnace with bolts, it should be noted that a gasket is required between the burner and the
furnace wall. The gasket may be ceramic fiber or glass fiber. When the burner is installed,
the burner can be arbitrarily rotated according to the site condition. When installation is
completed, then related components are made electrically connected.
The gas gun could be pushed in or pull out when the flame signal is not good during switch
from pilot to main burner.

9. Burner Main Fire Commissioning
1. Once the pilot is established, the main gas flow can be adjusted. Drive the control motor
to low fire.
2. Adjust the gas control valve opening to obtain a stable low fire flame.
3. Drive the gas control valve to high fire. Adjust gas pressure difference of burner inlet and
chamber to the range 75-87 mbar.

4. Drive the control valve to low fire and check for a stable low fire flame.
5. Cycle the temperature control valve to high fire and verify that the pressure drop is
consistent with the previous setting. Re-adjust if necessary.
6. As the incinerator comes up to temperature, backpressures and combustion air
temperatures will change. Make final burner adjustments after the incinerator has
reached its normal operating temperature.
10. Burner Maintenance
Preventive maintenance is the key to a reliable, safe and efficient combustion system. The
core of any preventive maintenance system is a list of periodic check list. These are
guidelines only. The customer should make the final determination on maintenance
intervals and tasks to be performed while considering the working environment.
System regular safety audit must be taken out, including gas leakage check no longer than
every half a year. If necessary, the frequency of audit should be increased. Leak detection,
and control functions of the equipment must be included in the scope of the audit. Only
Anderson technicians or those who are trained and qualified by Anderson, as well as other
relevant professionals, can maintain the burners. All valves, especially ball valves, must be
slowly open or close when switching in order to prevent pressure shock in pipe.
10.1 Half a year checklist
–Inspect the flame sensing devices for good condition and cleanliness.
–Check for proper air and gas pressures.
–Test all the system alarms for proper response signals.
–Check and clean igniter electrodes.
–Check actuators and control valves for free, smooth action and adjustment.
–Check for the proper operation of ventilating equipment.
–Test the interlock sequence on all safety equipment. Manually force each interlock
to intentionally fail while at the same time noting if related equipment closes or
stops as specified by the manufacturer. Test the flame safeguard by manually
shutting off the gas to the burner.
–Test the manual gas shut off cocks for proper operation.
10.2 Yearly checklist
–Leak test the safety shut-off valves and pipe for tightness of closure to make sure
no leakage.
–Test the pressure switch settings by checking the switch movements against
pressure settings and comparing these with the actual impulse pressure.
–Visually check igniter cable and connectors.
–Be sure the burner bodies and air wings, the ignite and the flame sensors are not
damaged or distorted.
