Found it in a corner of my basement I just cleared up, circular, metal, about a foot in diameter. Was covered with more foam, I took some off. Is it a sealed off drain pipe? What should I do with it?

Could be an old closed chimney pipe?
>>2549186it's at the end of a long crawlspace, I don't think anyone set up a stove there
>>2549172can you get better pictures? is that electrical hooked up to it? is it making any noise? any air movement around it?
