Ok im going to be the outsider here, A. it's a boiler, I would doubt the vapour carries anything that a vinegar/Junkahol run won't fix, B, Food grade is a lower standard than pressure vessels so I would be comfortable there, I've never seen a stainless pressure vessel rust. I wouldn't like to be doing hot work on it but I have my reasons for that (seen shit go wrong in gas plants) I would use it as a boiler, looks like it's in great knick.
