Dryer lint is the main active ingredient needed for a quickly spreading clothes dryer fire. As clothes dryer lint develops in the clothes dryer ducts air flow is obstructed. As air flow is decreased, heat and wetness can not easily leave. Now, the lint, that must be dry, is moist. It stays with the sides of your clothes dryer duct and attracts more lint. Add a small stimulate from inside the dryer to the lint developed up in your dryer duct to complete the dish for a destructive clothes dryer fire.
