- Railcar Fire Detector

From

0

The transportation of coal by rail brings with it the potential risk of fire. Coal stored and moved in rail cars can provide the environment necessary for coal to smolder, which if undetected leads to fire.

  • High speed thermal scanner
  • Processor provides peak picker temperature facility
 

  • Prevent hot inclusions entering the conveyor or storage areas
  • Fire avoidance - in personnel, downtime and repair costs
  • Automated process - Saves costs and man-hours
  • Improved plant safety
  • Higher confidence in safety of stored material

The transportation of coal by rail brings with it the potential risk of fire. Coal stored and moved in rail cars can provide the environment necessary for coal to smolder, which if undetected leads to fire.

The Railcar Fire Detector scans coal as it is unloaded and drops from the railcar through under track grates into a storage hopper (track hopper). Any hotspots or smoldering coal is detected and fire prevention action can be taken.

Coal Car Fire Detection

The system scans the coal as it is unloaded and drops from the railcar through under-track grates into a storage hopper (track hopper). Any hotspot or smouldering coal is detected and fire prevention action can be taken.

How the System Works

As each rail car arrives at the plant and unloads the coal, the curtain of falling coal is  temperature checked using aninfrared temperature scanner. This is located trackside and mounted horizontally to view the passing coal as it leaves the railcar. Any hot spots are picked up and used to trigger alarms to prevent widespread fire in the storage hopper or the subsequent conveyor system.

  • Railcar Fire Detector system consists of: Infrared LineScanner
  • Measurement ranges: 20 to 250 °C / 68 to 482 °F (higher ranges available)

The scanner is mounted horizontally below the railcar to scan the coal as it falls    out. It fits beside the railtrack to scan the entire width of the coal fall. It scans at up to 100 Hz the complete coal profile (80° scan angle). It is connected to the Processor via a Junction Box/Power Supply Unit. For full specification details refer to Product Data Sheet LSP60

Processor/Power Supply
The processor provides the power supply to the measuring head plus provides two independent 4-20mA temperature outputs. It processes the scanning head data and produces a peak temperature signal. This is output as a 4-20 mA signal. The processor also has available digital outputs for high temperature alarms (set by the customer). The processor will display a trend of the peak temperature gradient along the length of the conveyor. Importantly, no additional PC or software, hardware or associated complex wiring is needed.For full details refer to Product Data Sheet
