What are the specific methods for burner debugging and maintenance during low nitrogen transformatio

What are the specific methods for burner debugging and maintenance during low nitrogen transformation of industrial boilers?
1、 When ignition is not possible, correct measures should be taken
If it is found that the gas burner cannot be successfully ignited twice in a row when using a low nitrogen boiler, there may be some problems with the boiler. It is necessary to immediately shut down and conduct a detailed inspection. Manufacturers specializing in the production of low nitrogen gas boilers emphasize the importance of checking the gas supply system of the combustion engine for any issues, as well as checking for circuit connections that are disconnected. After identifying the cause, repairs should be carried out promptly to ensure that there are no issues before restarting.
2、 Prevent open flames or sparks
The main fuel for low nitrogen gas boilers is natural gas, which is usually transported and reused through pipelines. During relevant debugging, it may not be possible to determine whether there is any gas leakage or other phenomena around the boiler. Therefore, it is absolutely not allowed to ignite open flames, smoke, sparks, or static electricity near the boiler, which are very dangerous and may cause fires or even explosions. Therefore, it is necessary to prevent these phenomena. The manufacturer of low nitrogen gas boilers emphasizes that smoking or forceful tapping on the metal casing on site is not allowed, and welding or cutting is not allowed to avoid major accidents.
3、 Before repairing valve group faults, safety measures should be taken
If the valve group of a low nitrogen gas boiler malfunctions and the gas supply pipeline is in a ventilated state, the main valve should be closed before disassembly and repair to prevent gas leakage. Then, the possible gas in the pipeline of the main valve guide valve group should be vented before disassembly and maintenance can be carried out. However, low nitrogen gas boiler manufacturers need to remind everyone that even if the body has been emptied, there may still be residual gas or liquid gas components on the pipeline wall. Therefore, it is necessary to avoid sparks or static electricity during maintenance to avoid accidents.
The above are the three aspects of debugging and maintenance precautions for gas burners during the renovation of low nitrogen gas boilers. In addition, the tools used during on-site debugging and repair must have explosion-proof function. Moreover, domestic professional low nitrogen gas boiler manufacturers remind that a steam supply pressure test must be conducted before the burner starts to check for any leakage. Only after confirming that there are no errors can it be used.
