I don't know that the reason those white vinyl ducts were banned for dryers is because of how well the vinyl burns. I expect it's got as much or more to do with the fact that those ducts impose so much resistance to air flow that they cause large amounts of lint to accumulate in them, and that accumulation of lint is a fire hazard.
