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. 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,

This type of burner can provide great temperature uniformity. The burner body is cast iron,
other parts are stainless steel. Combustion air and gas in the burner body flow to the
surface through different channels, and part of the combustion air and gas are premixed
before exiting the surface to optimize emissions and efficiency.
The combustion air is connected the burner through the air duct, by providing the correct
air volume and pressure to the burner. Brackets are used to support the burner or air duct,
and fuel flow adjustment is achieved through a flow control valve. Ignition is ignited by a
separate point burner. Flame monitoring equipment can be placed at both ends of the
burner. The air pressure switch can be installed on the burner to detect whether the
pressure of the combustion air meets the requirements.
ANM76 Series Burner Advantage:
–Excellent emission: NOXand CO emissions are very low.
–Compact structure, with large heat input.

10.Burner Installation
Check before mounting:
–Burner body modules are connected securely with no obstruction.
–Remove dust and other particles inside burner if any
–Check if any obstructions in burner air duct
–Gaskets between burner and duct flanges
–Check alignment of system.
–Install UV-scanners on burner
11.Burner start
Special attention:
The ANM76 Series burners, described herein, are designed to mix fuel with ai. All fuel
burning devices are capable of producing fires and explosions, if improperly applied,
installed, adjusted, controlled, or maintained. Do not bypass any safety logics; Never try
to light a burner if it shows signs of damage or malfunction.
11.1 Pre-commissioning Requirements
Gas supply pipework up to the isolating ball valve should be pressure tested and
purged.
Gas to be available at a pressure between 80% and 100% of supply pressure at system
inlet.
If pneumatic shut off valves are used, make sure the compressed air inlet pressure is
at least 4.0 bar.
Electrical supply to the Burner Management System should be supplied at specified
voltage and frequency.
All field wiring from the burner management panel to the equipment should be
installed and tested according to the wiring diagrams.
All three phase power cables to electrical motors should be installed. Combustion air
fan, auxiliary air fan should be checked for correct rotation direction. Thermal overload
devices should be preliminary set.
Process air temperature should follow this manual technical description. The
mentioned process flow should be available for extended periods adequate for burner
commissioning to continue. Make sure no impurities flow into the combustion air
chamber.
11.2 Commissioning Procedure
1. Visual inspection of the burner equipment, paying particular attention to the
support structure of the gas pipe work. Inspect internal duct, looking for
mechanical damage to the burner.
2. Set and adjust the position of the auxiliary profile plate of process air across burner,
measure the pressure in the air duct with a pressure gauge, and ensure that the
DP before and after the profile plate reaches the required value, thereby
determining the maximum position of the profile plate. In actual operation, the
differential pressure switch is usually set to detect the process air pressure

difference before and after the burner profile plate.
3. Start the combustion air fan, adjust it to 100% of the flow rate, measure the
pressure difference between the combustion air and the downstream of the
burner, the design DP is 2-2.5 mbar.
4. Modulate through full range of burner input capacity, check the air DP and
combustion air flow.
5. For dry run test, first close the manual valve closest to the burner, then start the
control program, and start the dry test of the burner. Doing such a dry test can
check all the interlocking conditions in the combustion system, such as gas
pressure switches, air pressure switches, and leak test system.
6. Then carry out the pilot burner commissioning; procedure is carried out until
reliable ignition is achieved and the flame signal of the pilot ignition can feed back
to the flame controller with stable flame signal. During ignition test, the gas valve
before burner should be closed.
7. After the stable ignition is established, open the gas valve before burner.
8. First, setup low fire. At this time, the control system should be set in the manual
mode, which is set by adjusting to the minimum firing position. The gas volume at
this position requires the flame to propagate across sectional area of the burner,
that is, all modules will be firing. The flame detector detects the far end of the
burner. Since the flame propagate to the far end of burner will take time, the time
setting of the flame relay can be adjusted at this moment, to make sure both flame
detectors will be active to monitor flame after the delay time is over.
9. The relevant pressure and gas flow values need to be recorded during the
commissioning process.
10. Then set the high fire rate. This is achieved by using the manual control of the
process controller driving the modulating gas valve open step by step. Each step
of the ramp up to the maximum rate being monitored, gas flows recorded as not
to exceed the required rate. On reaching the fully open position, the main gas
pressure regulator can be set to give the required heat capacity.
11. After the high fire is set, low fire position should be checked again for fire rate and
reliable ignition. This can be cycled couple times to ensure low fire-high fire-low
fire-high fire firing stable.
12. All pressure switches shall also be tested by reducing or increasing the setpoints
until system trip. Relevant alarm procedures and control logic checked. Trip
positions recorded and normal operation setpoints selected and set.
Note: The above procedure will be carried out by using the process air flow.
11.3 Start Burner
After all firing rate is setup, the burner gets into operation mode, the gas flow control
valve is controlled by 4-20 mA from temperature controller. The pilot burner could be
closed or run continuously according to the design requirements.

11.4 Stop Procedure
Do not turn the combustion air blower off until the chamber temperature is below
80°C. This will prevent hot gases from back flowing into the burner and blower, which
may cause damage to the burner.
–Stop the burner through the burner control system.
–Run the combustion air blower until the chamber temperature drops below 80°C.
–Turn off the combustion air blower.
–Close all manual gas valves to the burner.
12.Burner Maintenance
Preventive maintenance is the key to a reliable, safe and efficient system. The good habit
of any preventive maintenance system is setup and follow up the periodic checklist.
Customer should make the final determination on maintenance intervals and tasks to be
performed while considering the working condition and environment.
System routine safety audit must be taken including gas leak test at least half a year. If
necessary, the frequency of audit should be increased. Leak detect, control functions of the
equipment must be included in the scope of 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 in order to
prevent pressure surge in pipe. Please pay more attention to the following items as
consider preventing maintenance
–Examine and, if necessary, clean, replace any gas or air filter elements
–Check all bolts tightness.
–Check all piping connections for leaks.
–Inspect the flame monitoring device and maintain in accordance with manufacturer’s
instructions.
–Check the function of all pressure switches.
–Check function of all limit switches.
12.1 Half year checklist
–Inspect the flame sensing devices for good condition and cleanliness.
–Check for proper air and gas pressures.
–Test all the system alarm signals for proper response.
–Check and clean igniter electrodes.
–Check valve actuators and control valves for free, smooth movement.
–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.
–Inspect and clean the combustion air blower rotor. Clean and/or replace the
combustion air blower filter if applicable.
