Yankee Dryer and Drive Side Protection
Due to the large amount of dust accumulation around the Yankee Hood, Yankee Dryer and the Drive Side of the machine, the risk of fire in these areas is considered very high.
Firefly’s Quick Suppression System that combine advanced and reliable flame detectors with water mist suppression nozzles will be located to cover the risk zones around the Yankee Dryer.
One of the most common areas for fires is in and around the Doctor Blade area. Friction created by Doctor Blades in combination with and accumulation of dust can cause fires which can spread rapidly.
Firefly WebScan System
Friction at the Doctor Blade and smouldering particles from the Yankee Dryer can create dangerous ignition sources such as hot, dark particles and glowing embers.
To prevent fire in stored parent roles, Firefly has developed the WebScan. The system consists of True IR Spark Detectors mounted above the tissue sheet between the Yankee Dryer and the Reel-Up.
Reel Up Area Protection
Dust build up and tissue debris occurs in this area and is very combustible.
Dust Extraction Protection
To reduce the dust accumulation and keep the tissue web clean from dust some machines are equipped with dust extraction systems. Firefly True IR Spark Detectors and Water Mist Nozzles can be located in the outlet duct work for a combined reliable solution.
Ignition sources can be generated from the shredding process and fires will most likely occur in the cyclone or filter where the shredded material is pneumatically conveyed.
