As the area around the dry end of the Yankee dryer is usually dusty, a small smouldering fire can easily be spread by the rotation of the Yankee cylinder. As a result, ignition sources can be scattered to an even larger area. Once the fire has got a grip, particularly on the drive side of the tissue machine, the fire becomes not only dangerous but also difficult to extinguish without contributing to additional costly downtime.
This is where Firefly and their OAD (Open Area Detector) comes in. Effective extinguishing with water mist will quickly put out the fire with minimal effect on the process.
Conventional extinguishing methods generally require massive amounts of water to extinguish.
