Gas burner start-up operation
1. Before debugging a new boiler, you should carefully check whether the gas meets the fuel requirements of the burner, check whether the detection instruments on the gas supply pipeline are normal, whether the pipeline valve switches are normal, and whether it is convenient for future use and maintenance.
2. For boiler piping, the installation reliability of all pipelines and the tightness of the pipelines should be carefully checked.
3. Manufacturers using private gasification stations must ensure that the gas volume and gas supply parameters meet safe combustion requirements.
4． Operators carefully read the equipment instruction manual and master the knowledge and methods of safe operation.
5. Check whether the gas valve is open before starting each time, otherwise the burner will not work.
6． Start the power control button on the control cabinet. At this time, the digital display will display the current temperature in the furnace. This temperature of the newly installed furnace body is the ambient temperature.
7. Turn on the fan control button and the fan installed on the furnace body will work. At this time, if the fan is damaged, the control cabinet will be automatically protected from entering the next operation.
8. When the combustion fan works without abnormality, start the combustion control button again. At this time, the combustion program controller starts to work. It carries out ignition, air supply, flame detection, etc. through certain procedures to finally achieve safe combustion.
9. When the combustion controller receives signals that are not conducive to combustion (for example: ignition failure, unstable air pressure, circuit problems) and other problems, the combustion controller immediately turns off the gas and sends an alarm signal.
10. If the combustion controller alarms, it must be manually reset by the operator after the fault is resolved before it can continue to work.
11. For the operation of the entire equipment, operators should refer to the furnace safety operating procedures and production process requirements.
12. When the control temperature needs to be adjusted according to the production process requirements, the operator should refer to the boiler manual, burner user manual, and intelligent CNC meter manual for adjustment.
Gas burner shutdown operation
1. There are two situations of shutdown: the first is: when the temperature in the furnace reaches the set value, it will automatically shut down. The operator does not need to do anything at this time. The controller will automatically turn on when the temperature in the furnace is lower than the set value.
2. The second is: during manual shutdown or shift handover shutdown, the operator should turn off the combustion control button in the reverse order (a. Turn off the combustion control button first, b. Then turn off the fan button, c. Finally turn off the power button ) operation to shut down.
3. When the shutdown time is long, the operator should close the gas pipeline valve to avoid gas leakage.
Gas burner debugging
(1) Before debugging the gas burner, check whether the gas is in place, whether the gas pipeline is clean and smooth, and whether the valve is open.
(2) Whether there is any pipeline leakage and whether the pipeline installation is reasonable.
(3) Bleed the air from the pipe in front of the gas valve to ensure that there is no mixed air in the pipe. At the same time, the drain pipe should be connected to the outside.
Then perform an internal inspection of the burner
Check whether the combustion head of the burner is installed and adjusted properly.
Check whether the direction of motor rotation is correct.
Check whether the external circuit connection meets the requirements.
Check, conduct a cold state simulation of the burner according to the circuit conditions, and observe whether each component of the equipment during operation is normal and whether the flame detection and protection part is normal.
Gas burner starts debugging
① Check whether the external gas is in place, the pipeline is unobstructed, and the external power supply control is in place.
② Adjust the load of the burner to a small load, adjust the ignition position to a small load accordingly, turn off the large load for ignition and observe the flame condition, and adjust the servo motor or damper and gas valve group accordingly according to the flame condition.
③ When adjusting the high-fire output of the burner, it is necessary to gradually adjust from a relatively small load to a large load according to the load of the heating equipment, and adjust the servo motor or damper accordingly according to the situation.
④ Observe whether the flame is partial, insufficient flame burning, vibration, etc.
⑤ After adjustment, ignite several times to see if the ignition is good.
Gas burner, fault repair
❶ When the gas burner continuously fails the secondary ignition program, stop it immediately and check whether the gas supply system of the burner is normal, whether the circuit connection is correct, whether the motor running direction is forward, whether the air inlet valve is working normally or reset to zero, and whether the voltage Is it stable?
❷ It is strictly forbidden to have open flames or leaks near the gas supply pipeline to prevent gas explosion.
❸ Check whether the program controller in the burner's main unit is damaged and whether the circuit is normal.
❹ Check whether the burner's automatic air inlet is functioning properly.
❺ Test whether there is gas in the gas supply pipeline. Usually use a gas low pressure gauge to check the gas supply pressure.
❻ If there is no problem with the gas pressure and gas pipeline, check whether the electric valve bleeds the air from the gas pipeline.
❼ When the gas supply pipeline is ventilated and the valve group is faulty, it needs to be disassembled. First, the main valve at the front of the valve group must be cut off, and then the gas in the pipeline from the main valve to the valve group must be vented, and then the valve group can be disassembled and repaired. .
❽ During maintenance and debugging, boilers, burners or pipes and other equipment must be operated and maintained by professional persons in charge to prevent damage to equipment parameters and machines and affect normal production.
❾ If the burner suddenly fails during production and you cannot find out the fault by yourself, it is recommended to contact the technical personnel of the burner manufacturer for video or guidance to help solve the problem.
