Conveyor belt temperature monitoring and fire detection Conveyor belts running in dusty and harsh environments, such as mines, run the risk of overheating bearings that can lead to catastrophic fires - especially when transporting flammable material like coal.
sufficient to ignite coal dust, CH4, coal dust/ air mixture or any hydrocarbon vapors from the grease, paint, seal etc. Fire Resistant (FR) grease has been adopted for idler end bearings in the UK coal mining industry since 1986 as it is less likely to ignite if exuded from a bearing during collapse.
The general rule in fire protection systems for conveyors is to locate Ember Detector(s) upstream from a change in direction (transfer to another conveyor) or a dust producing process or storage point. Hence, once the ember is detected, it can be extinguished before it enters the next process where it can cause a potential explosion.
cases, especially in enclosed spaces, the location of the sensor cable may have to be closer to the conveyor ceiling height. This type of application is a so called "room protection" application, where the sensor cable is located at a distance away from the main fire risk. "Room Protection" is defined within EN54 part 22 para 3.1.12.
