Increase the nitrogen protection setting. There’s no good solution.
Check whether the protective gas pipeline is blocked
Protect the viewing port with air or nitrogen to prevent carbon in acidic gases from adhering to the sight glass.
Our viewing ports use unpurified air along with fan air for backflow purification, in order to protect the viewing lenses

The formation of soot in the flame viewing port is usually caused by wind, nitrogen carrying dirt, or sulfur present inside the furnace; it is necessary to prevent the entry of dirt and to ensure that the pressure outside is not higher than that inside the furnace. If the port becomes blocked, the only options are to stop operations for maintenance or to handle the issue in case of an emergency shutdown.
Isn’t there a backflow protection valve? It is best to have two gas sources; in case of problems, the second source can provide an alternative solution
That’s right; there’s reverse airflow, so it usually doesn’t get clogged. Try increasing the air volume.
Pay attention to the reverse airflow protection; during regular inspections, make sure to adjust the blowing air properly! When one type of airflow encounters a problem, it switches to another type in time to prevent no airflow!
To maintain an uninterrupted backdraft, the fire viewing holes will not become clogged. Generally, there are two types of air sources used for backwashing in design: one is the air from the sulfur production furnace blower, which has a relatively low pressure. The second is unpurified air, which has stable and high pressure and is reliable; therefore, the latter is preferable.
If the backflow pressure is very stable. (It ensures that the pressure remains normal under normal conditions.) Constant wind). We should check the upstream devices that supply air to see if there are any issues with the quality of the reverse airflow. I do not recommend using the air from a fan as the backdraft air for the fire viewing port. There are too many impurities
