Re: Fire Protection Measures In Long Overland Conveyors
Kayem,
There are ways to do so. Coal fired power plants use such devices to protect against deflagration from idler bearing heating.
A protective circuit is used that is threaded to each idler bearing set. Excessive heat will annuciate the location.
If the conveyor is covered, then the concept works like the power plant reclaim tunnels using the same device as above.
You must identify: Causes, Detections, Preventions, Corrections.
For the above you can write a book which I am not. CDI is skilled in the virtues of the above and offer the service to clients. Are you an intersted client?

Fire Detection And Fire Fighting
Fire detection in sponge iron, as there are no visible flames , runaway reoxidation in its early stages is detected by a change of coloration of the sponge iron itself , it turns dark bluegray.
Infrarred sensing at 11 microns wave length range will give very good reponse and will have little solar interference or noise.
sensing spot should be small enough to detect a 10 pellet spot at 600 degrees c in a background of 45 degrees c.
This will normally mean a spot of 12 inches wide , with the actual ir scanners available this poses no problem.
Fixed staring sensors with or without choppers are used widely in industry and with the proper carriers provide acceptable results.

Fire Protection Measures in Long Overland Conveyors
Could someone guide me to authentic information about Fire Protection systems employed in long overland conveyor systems ?
The case in question concerns two conveyors, each about 5500 m long passing through partly unpopulated and partly populated terrain. The conveyor is primarily at ground level and there is no extraordinary protection against deliberate sabotage.
Some advise from those experienced in such matters would help.
Regards
