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. 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.

Compared with other types of Anderson burners, VFS82 series burners with:
–High turndown capabilities on a wide range of fuels result from the stable flame
produced by the swirl air.
–Clean, smoke-free combustion results from the unique “vortex generator” which
vaporizes fuel oils.
–Low NOx and CO emissions.
–Rugged heavy gauge steel wind box and volute assemblies provide durability.
–Operates with low excess air for maximum efficiency or high excess air for high
volume process air heating.
–Single wall alloy, air-cooled alloy, and refractory versions available.
–Standard firing arrangement is horizontal but can be fired vertically with additional
gas lance support rods.
–suitable for different kinds of fuels such as natural gas, propane, light oil, or heavy oil.
5.2 VFS82 Series Burner Introduction
VFS82 series burner includes burner body, gas or oil nozzle, ignition burner, spark rod and
peep sight, vortex generator components, flame monitor device, etc. It is to be noted that
flame monitoring must be provided by an ultraviolet scanner. For gas fuel application, can

5.3 Ignition Burner
VFS82 Series Burner has a separated ignition burner of maximum capacity 50kw. User need
to supply fresh combustion air for ignition pilot, so, a small air blower or compressed air
needs to be applied to the pilot burner. According to pilot burner's manual, 5mbar
combustion air and 3mbar gas pressure are necessary for pilot burner operation. The
pressure above is needed for neutral environment, if oven chamber pressure is not neutral,
chamber pressure needs to be added to the pressure value above. It should be noted that
the depth of ignition burner extend to main burner is adjustable according to site
requirement. Pilot burner diagram shown as Fig. 2 as blew.

7. VFS82G Series Burner Installation
When installing this series of burners, the burner is fixed to the mounting hole of the
furnace with bolts, it sholuld 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 rotated according to the site condition. After burner is installed,
make the related components wired. The combustion air inlet pipeline of the combustor
could be moved in the normal direction. It could be moved and adjusted when the flame
signal is not good or the occurrence of a ringing phenomenon occurs in the ignition area.

8. Burner Start, Commissioning and Stop
For the first time burner startup, then you must follow these steps:
1. Reset the System:
Close the automatic fuel shut-off valves and the fuel cocks.
2. Set High Fire Combustion Air Pressure Drop:
Start the combustion air fan.
Set the air control damper to produce the desired high fire pressure drop across the
burner. Air pressure drop should be read as a differential pressure between the wind box
pressure test port and the chamber. See the datasheets for the combustion air pressure
drop versus air flow curves.
3. Verify Air Settings:
Make sure that all the settings are still the same after you cycle the system several times
between high fire and low fire. Check the air proving switch and adjust if necessary.
4. Ignition pilot burner:
Run the system only with ignition pilot burner, adjust combustion air and gas pressure
to get stable flame signal. Please refer to relative pilot burner datasheet.
5. Main burner ignition:
Make sure the combustion air fan is running. Adjust the main gas regulator to supply the
minimum pressure required; see the datasheets for gas pressure drop information.
Verify that the main gas control valve is at its minimum open position. Light the pilot.
Open all manual fuel shut-off valves. Initiate the ignition sequence through the flame
safety. Check that the pilot and main burner flames are ignited. Measure the gas
pressure drop, taken between the burner pressure taps as indicated on the datasheets
and a tap in the combustion chamber. The gas flame should be pale blue color set inside
the refractory combustion block. Low fire setting finished.
6. Adjust High Fire:
Drive the main gas control valve to high fire. Measure the gas and air pressure drops at
high fire and compare to the appropriate chart on the datasheets. If the maximum input
is not achieved or is too high, an adjustment can be made to the main gas control valve
or the main gas pressure regulator can be adjusted higher or lower. The main gas flame
should be slightly blue periphery and a somewhat yellowish center at high fire, refer to
datasheets for flame length estimates.
7. Verify Settings:
Once the high and low fire conditions have been set, cycle the burner from high to low
fire several times to check repeatability of settings. Shut down the burner and relight to
ensure automated pilot and main flame ignition operates correctly. Check all safety
interlocks and limits to ensure proper operation.
8. Stop Procedure:
Drive combustion air and gas valves to low fire position. Shut off main gas supply valves
and pilot. Leave combustion air at low fire until combustion chamber and block are
cooled to under 80°C; once cooled, shut off combustion air fan. Shut off all manual valves

as required.
9. 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 tasks. 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,
control functions of the equipment must be included in the scope of audit. Only Anderson
technicians or those who are been 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.
9.1 Bi-annual 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 valve motors 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.
9.2 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.
