Attached are photos of the inside of the old 304 duct (we finally replaced the quencher duct). Have anyone seen this type of corrosion pattern? The loss of metal thickness is highly localized and very severe.
Thank you all for your advice!
To EdStainless: we are developing a source gas testing spec, will incorporate testing for all halogens in addition to sulfur species, N2, CO2 and methane.
To racookpe1978: there is no way to introduce water earlier due to high temperatures (that would simply mean...
I'm trying to figure if 316 patches welded on a badly corroded 304 body of a temporary quencher would accelerate corrosion. The duct, acting as a quencher takes 1000F sour gas (exhaust of a thermal oxidizer processing ~50,000 ppm H2S and ~40,000 ppm methane landfill gas) and cools it down to...
