One I distinctly recall is my mother telling me how another couple at the hall had some items in their attic that had gotten demon possessed. So they took the aforementioned items outside to burn them, but the demons were preventing the items from burning (items made from wood, cardboard, paper, clothing, etc). They even doused all the items with gasoline and yet the demons prevented them all from ever catching flame. Eventually they hauled the items away to a dump since they were permanently demonically inflammable.
I swear i was told this exact same story by my sister when i was a kid.
Incidentally, i burn a lot of waste wood and paper-crap in my backyard and it's not always easy to get books to burn. It takes a few goes, there a knack to it.
