Slash-burning device helps firefighters cut down on smoke going into atmosphere


The Kootenai national Forest is sharing video of air curtain burners.

Crews are using them on the Gold Hill fire 13 miles north of Libby, to dispose of slash from fire line and fuel break operations.

Technicians say these burners blow a curtain of air across the top and into a burn chamber to create an oxygen-rich environment which traps particulate (smoke) and ensures more complete combustion.

Fire managers say they are a good alternative to current fuel reduction and disposal methods because they cut down on smoke emissions, insect problems and future fire risk.

They also burn a bigger variety of materials and operate with fewer restrictions in weather and burn conditions.
