Flammable raw materials, which are in small-scale form, harbor a permanent danger potential. In conjunction with atmospheric oxygen, these materials form an explosive atmosphere. If an ignition source is added, devastating fires and dust explosions can result.
In industrial production, raw materials are heavily comminuted; therefore, mechanical conveying paths are a major component of production facilities. However, not only bulk goods are transported via this connection. Sparks or glowing parts can also be produced in processing machines or dryers and thus represent a considerable risk of fire and explosion for downstream system components such as filters and silos.
A fire or a dust explosion occurs whenever three conditions are met at the same time: flammable dusts, air (oxygen) and an effective ignition source. If these requirements are fulfilled, an explosion event can take place.
- Fire or explosion in downstream processes by transfer of embers or glowing particles
- Fire or explosion on the conveying facility itseld by self-ignition during transport
- Fire on the conveyor due to overheated bearings or drives
If possible, place the detectors in a position where the material is falling
With the help of the graphical long-term monitoring, overheating can be detected by temperature trends at an early stage.
Change bearing to avoid a fire on the conveyor due to overheated bearings.
- Detection of ignition effective points on the conveyor
- Detection of incipient fires to avoid damage to the conveyor or downstream areas
- Deletion of potential dangers
