High-pressure nitrogen enters the gasification furnace from the furnace wall

If it is in the quench chamber, then it is as mentioned on the second floor. If it is in the gasification chamber, it should be protective nitrogen for the pressure gauge interface.
Indeed, as wildhalf upstairs said, it would be best for Brother Vaporization to confirm the flow rate of high-pressure nitrogen first; checking whether it is below 5 m3/h will help determine whether it is the protective nitrogen used at the pressure gauge interface.
I took a look; it seems to be a pressure tapping pipeline, but the diagram isn’t clear, so it’s just my guess.
What kind of furnace is it? If it’s a SHELL furnace, there are purge ports in the annular space to prevent dust accumulation (continuous)
For Texaco stoves, I see that some have this feature while others don’t.
The Texaco pressure tap is filled with high-pressure nitrogen, which serves to protect the tap
It’s not for purging; it’s located a little below the vault, and it’s not connected to the vaporizer.
I also heard someone say that during the operation of the wet gasification furnace, a small flow of nitrogen continuously enters the furnace chamber; I’m not sure what the purpose of that is
