During low-nitrogen modification of industrial boilers, what are the specific methods for burner tuning and maintenance?
1. If the burner cannot be ignited, the correct handling should be taken. If the gas burner fails to ignite continuously for two times during the use of low-nitrogen boiler, there may be some problems with the boiler. It is necessary to immediately stop the machine and conduct a detailed inspection. Professional manufacturers of low-nitrogen gas boilers emphasize that it is especially important to check whether there are problems with the gas supply system of the burner, and to check whether there are any conditions such as disconnection of electrical wires. After identifying the cause, repair it in a timely manner to ensure that there are no problems, and then start the machine again.
2. Prevent open flames or sparks Low-nitrogen gas boilers are the main fuel for natural gas, which is usually transported through pipelines and then used. During the relevant tuning, it may not be possible to determine whether there are leakage phenomena such as gas leakage around the boiler, so it is absolutely prohibited to ignite open flames or even smoke, have sparks or static electricity, and it is dangerous to have these phenomena. Therefore, it is necessary to prevent these phenomena. It is not allowed to smoke or vigorously knock on the metal outer shell, let alone welding or cutting, to avoid major accidents.
3. Safety measures should be taken before repairing valve groups If the valve group of the low-nitrogen gas boiler fails and the gas supply pipeline is in a state of air supply, before disassembling and repairing it, the main valve should be closed to prevent gas leakage. Then, the gas in the pipeline section that may exist in the main valve and valve group should be drained. However, the low-nitrogen gas boiler manufacturer reminds that even if the machine has been drained, the pipeline wall may still retain gas or liquid fuel components, so it is necessary to avoid sparks or static electricity during repair, to avoid accidents.
These are the three aspects that the low-nitrogen gas boiler modification involves in the burner tuning and maintenance. In addition, during the on-site tuning and repair process, the tools used must have explosion-proof functionality. In addition, the professional domestic low-nitrogen gas boiler manufacturer reminds that a pressure test of the gas supply must be carried out before the burner is started, and whether there are leakage phenomena should be checked. After determining that there are no problems, the machine can be used.
