High fire gas setting: drive burner to high fire, set gas differential pressure between
burner and chamber according to the datasheet of relative type of burner. Then
drive the burner to low fire and back to high fire again, to check the differential
pressure. Make several recycles till the differential pressure remains the same.
7.
Low fire gas setting: Drive the system to low fire. Setting low fire gas differential
pressure according to datasheet of relative type of burner This is target value for
low fire. Drive burner to high fire then go back to low fire, to check differential
pressure. Make several recycles of low and high fire change till the differential
pressure not change.
NOTE:
It is very difficult to measure the very low pressures for low fire, and it may be
necessary to rely on visual inspection. This is especially true when gas turndowns is over
20:1. The main intent is to provide a stable flame with a good flame signal that will not
cause the furnace temperature to overshoot.
8.
Verify the Gas Settings: Make sure that all settings are still the same after cycling,
the system several times between high and low fire.
10.9 Start burner
1.
Start blower.
2.
Open all the valves including automotive and manual valves.
3.
Start ignition procedure.
4.
Confirm the ignition procedure finished then control valve opening is controlled
by 4-20 mA.
10.10 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 causing damage
to the burner.
1.
Stop the burner through the burner control system.
2.
Run the combustion air blower until the chamber temperature drops below 80°C.
3.
Turn off the combustion air blower.
4.
Close all manual gas valves to the burner
5.
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.
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 checks 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
