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.

–

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.

– 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.
