In modern industrial manufacturing, boilers are generally equipped with boiler burners, and boiler burners play an important role in the boiler system and are the main equipment of the combustion system. So as equipment, how to use, debug and operate precautions are very important for every worker. In order to ensure safe commissioning operations, the burner operating standards of boiler burners are as follows
The first is the requirements for the boiler site:
1. Personnel irrelevant to the commissioning operation are required to leave the operation site.
2. Any other operation (such as electric welding, gas cutting, etc.) is prohibited.
3. In order to ensure the personal safety of the commissioning personnel, when the burner is ignited, it should be 1 meter away from the side of the burner. When the flame is burning stably, the flame can be observed at the observation mirror, and the next step of output adjustment and other adjustments can be made.
Then check the inside of the gas burner
1. Whether the combustion head of the burner is installed and adjusted well.
2. Whether the direction of motor rotation is correct.
3. Whether the external circuit connection meets the requirements.
4. Carry out cold state simulation of the burner according to the circuit conditions, and observe whether the various components of the equipment in operation are normal and whether the flame detection and protection part is normal.
Then it is about the inspection before the burner debugging
1. 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. Exhaust air from the pipeline in front of the gas valve to ensure that there is no mixed air in the pipeline, and the exhaust pipe should be installed outside.
Finally, the 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 is necessary to gradually adjust from a relatively small load to a large load according to the load of the heat-consuming equipment, and adjust the servo motor or damper accordingly according to the situation.
4. Observe whether the flame has partial fire, insufficient flame combustion, vibration and other phenomena.
5. After the adjustment, the ignition should be carried out several times to observe whether the ignition is good.
The fuel of the boiler gas burner is a flammable and explosive dangerous gas. Care should be taken to protect and prevent it during use and storage, otherwise major safety accidents will occur. The above points must be kept in mind.
