The burner plays a very important role in boiler equipment. Let me tell you about the precautions for burner debugging and maintenance:
Commissioning of the burner
1. Check whether the external gas is in place, whether the pipeline is unobstructed, and whether the external power supply 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 to ignite and observe the flame situation, and adjust the servo motor or damper and gas valve group accordingly according to the flame situation.
3. When adjusting the high fire output of the burner, it should be adjusted gradually from a relatively small load to a large load according to the load of the heat-consuming equipment, and the servo motor or damper should be adjusted accordingly according to the situation.
4. Observe whether the flame has partial fire, insufficient flame combustion, vibration and other phenomena.
5. After the adjustment, it is necessary to carry out multiple ignitions to observe whether the ignition is good.
Precautions for burner maintenance
1. It is strictly forbidden to tap or rub the gas supply pipeline with a wrench or a metal rod to avoid static electricity or sparks, which may cause a gas explosion.
2. When the gas burner fails in the secondary ignition procedure continuously, stop the machine to check whether the gas supply system of the burner is normal and whether the circuit connection is correct. The burner can only be restarted after troubleshooting.
3. Smoking, welding, cutting and other illegal operations are strictly prohibited on the gas supply valve group or the flange surface of the pipeline.
4. Test whether there is fuel in the gas supply pipeline, usually with a gas low pressure gauge.
5. It is strictly forbidden to conduct any open flame test next to the pipeline, valve group and pressure regulating valve to avoid major accidents.
6. In the gas supply pipeline, it has been evacuated, but there are residual gas or liquid droplets on the pipe wall, which will also cause combustion and explosion in case of static sparks and open flames.
7. Before the burner is started, it is necessary to do a gas supply pressure test to check whether there is any leakage. After confirming that it is normal, do a simulated operation.
8. It is forbidden to use non-explosion-proof electrical and electric tools on site.
9. In the commissioning work, the gas must be serious, safe and efficient.
10. When the gas supply pipeline has been ventilated and the valve group is faulty, it needs to be disassembled. First, the main valve at the front end 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. repair.
11. Explain the precautions for safe operation to customers in detail.
12. When the burner is not in use, tell the customer to cut off the main gas supply valve and the main power supply switch.
13. At the end of the commissioning, it is necessary to organize operators to carry out training on the direction of use and operation, and establish an operation process if necessary.
14. It is recommended not to debug the burner at night.
