Superheater perforation
Thread Content
In the production of aluminum fluoride, perforations often occur in the superheaters. I would like to ask the experts: how can such perforations be avoided?
Internal anti-corrosion, or addition of external protective measures
Please briefly describe the operating conditions; only then can we provide an appropriate solution.
Our process here is as follows: anhydrous hydrofluoric acid enters the anhydrous hydrofluoric acid receiving tank from a middle tank, and then passes through pipes at the bottom of the receiving tank to an anhydrous acid heater where it is heated to a gaseous state. After that, it passes through a superheater and enters a fluidized bed. The liquid level in the liquid receiving tank is generally maintained at 40-60%. The superheater outlet temperature is maintained above 40 degrees
The superheaters here have not been in use for long periods of time, (ˇˍˇ) I was wondering – could those of you who know more tell me which manufacturers have had their superheaters in use for the longest time?
What material is the superheater made of? It can’t be carbon steel, right? To ensure a longer usage time, it is recommended to use 825
