This way the fire prevention system can automatically prevent or extinguish coal fires, enhancing plant safety and ensuring the continuity of the power production." Automatic temperature alarm One FLIR A310 thermal imaging camera is installed at the storage end, checking the coal as it enters the conveyor system.
The shaft which holds the tray, will rotate, setting off the switch, thus causing a trip and subsequent stoppage of the conveyor. In environments, where large material accumulates on the tray such as crushed coal or iron ore, material can build up on the tray producing enough weight on the tray to cause unnecessary trips.
