The transportation of coal on any form of conveyor system has the potential to ignite, with the ultimate outcome being a fire. Coal (even in small amounts) is a very good insulator, so fire which is burning beneath the surface may not be immediately obvious. A single point temperature measurement system can detect a hot spot, but is just as often likely to miss one.
Temperature Scanning - real benefits
A scanning temperature measurement system which looks at the entire width of the conveyor at any one time is an ideal solution. It scans at a wide angle (the entire conveyor width), at high speed and with a fast response. Every hot spot can be detected as all the coal surface is viewed. The scanner is capable of detecting even small hot objects on the conveyor, with its high-speed scanned detector. The scanner outputs the hottest temperature on the conveyor directly to a plant control system or suitable customer alarm system.
The system is mounted above the conveyor and is connected via a single 8-core cable to the processor unit (usually mounted in a control room). The processor powers the scanner and also provides the signal outputs. The scanner is highly robust with a range of mounting and protection accessories.
Conveyor belts are expensive and replacements can carry long lead times - maximize your belt life and plant productivity by detecting hotspots before problems occur.
