In the minds of many people, nitrogen seems a bit distant from boiler systems. But in fact, whether it is a gas boiler, an oil-fired boiler or a pulverized coal boiler, nitrogen plays an irreplaceable role in the daily operation and maintenance process. Here introduce three common but often overlooked application scenarios of nitrogen in boiler systems.
1.Boiler Purging
Before the boiler starts up and after it stops, nitrogen purging treatment is required. This is to completely expel flammable gases or residual air in the pipelines and combustion chamber to prevent an explosion when ignited. Moreover, purging with nitrogen is safer than using air alone. Because nitrogen is an inert gas and non-flammable, it can effectively reduce the concentration of oxygen and prevent accidents caused by mixed gases during ignition.
2. Nitrogen Seal of the Fuel Storage Tank
Whether it is a heavy oil tank, a diesel tank or a natural gas buffer tank, the oxygen concentration in the tanks storing these fuels must be well controlled during operation. Injecting nitrogen to form a nitrogen seal means adding a layer of nitrogen protective layer on the top of the tank to isolate the air and prevent oxygen from entering the tank and mixing with the volatile fuel to form explosive gas. The benefits of doing this are not only explosion prevention, but also reducing the oxidation of oil products and extending the storage time.
3. Inert Isolation During the Equipment Maintenance Period
When a boiler system or fuel pipeline needs maintenance, if it is directly exposed to the air, it is easy for residual fuel gas or dust to form a dangerous atmosphere when it meets the air. At this point, introducing nitrogen for “inert gas isolation” can effectively remove oxygen and moisture, creating a safe environment that ensures the safety of maintenance personnel and also prevents secondary pollution of the equipment.
Nowadays, many enterprises choose on-site nitrogen production to replace bottled nitrogen, which not only saves costs but is also more flexible and efficient. The PSA nitrogen generator provided by our Nuzhuo can be customized with solutions based on the operating conditions and actual needs of the boiler. It features stable gas output, simple operation, and a high degree of automation, making it particularly suitable for long-term use in industrial sites.
