The intent is to consume fuel ahead of the main fire, strengthening the control line. A backfire is a more aggressive type of burning done to influence the behavior of the main fire. In forest and prairie management, the driptorch is the most common tool used to ignite prescribed burns, which are used to remove excess fuel buildup or to re ...

Drones have also been studied as tools for starting planned, controlled fires to clear out hard-to-kill underbrush. [4] It is called the "Dragon Egg System." These are similar to ping-pong balls but are filled with potassium permanganate powder and injected with glycol and dropped to the target site.
