Material of sulfur burning furnace nozzle
Thread Content
As the title suggests, I would like to ask what material the nozzles in the sulfur combustion furnaces used for acid production from sulfur are made of? Thank you!
May I ask what material the nozzles in the sulfur combustion furnace used for acid production with sulfur are made of? Answer: 310S heat-resistant stainless steel can be used ；
The material commonly used for sulfur nozzles is 25-20, which is Cr25Ni20.
Our company imports sulfide guns from Mengmoke Company, made of 309S material.
Thank you! In our company, liquid sulfur burns by dripping into the furnace; the sulfur guide pipes are made of 316 material. After being in use for half a year, they become as weak as tofu residue and break easily when snapped. So I’d like to try other materials. Thank you all!
Have you checked what the main components of 309S are? What are their respective contents?
Hehe, I’m using 304; it’s been about 6 years and it’s still in great condition
The main components of 309S are: C less than or equal to 0.08%, Si 1.0%, Mn less than or equal to 2.0%, Ni 12–15%, Cr 22–24%. This corresponds to the domestic grade 0Cr23Ni13.
It also belongs to the high-silicon, low-carbon alloy category. Actually, I once thought that using a heating wire alloy would give better results. I just don’t know how its machinability is, so I haven’t considered it yet.
