Production of hygienic articles firefly
The industry of diapers and hygienic products is recording millions in losses around the world due to unplanned interruptions in the production caused by fires or dust explosions. Many places in the diaper production plants are exposed to the accumulation of dry, flammable dust and cellulose fibres. There are many examples of situations around the world, in which the plants that manufacture diapers have been partially or completely destroyed by fires or dust explosions in the production process.
The main causes of fires in this type of processes are mills or fans, which through overloads or mechanical damages may generate sources of ignition. These sources of ignition may be transported via the duct systems and cause a fire or (in the worst case) a dust explosion in the forming section or in the filters. In the mills, there is also a risk that dust on the surface of the mill or around the mill may ignite and cause a fire in the mill.
The Firefly system solutions in the production of diapers and hygienic products focus mainly on the early stage detection of all incidents that could cause a fire or a dust explosion. The system reaction time is very quick, however not only the reaction time is the key to success of an efficient system. Firefly also uses a specially developed effect of infrared detectors, which detect sparks and flames, as well as hot black particles. These particles are often the first sign of an emerging problem in this type of processes.
Also, the location of sensors is important in order to ensure optimal operation of the system. All Firefly detectors are insensitive to daylight, which means that they may be placed near plexiglass windows without causing false alarms.
