Fire-protection guidelines for: Conveyors transporting coal

Fire-protection guidelines for: Conveyors transporting coal Conveyor systems in general have a fire risk due to external events and equipment failure. However the flammable nature of coal including the ability of some types to self ignite introduces an exceptional hazard requiring special consideration.

Fire Safety for Conveyor Systems - Patol

Fire Safety for Conveyor Systems To protect the upper side of the conveyor itself a detector “run” should be installed above the centre of the belt at a height of 1 to 1.5m. Normally this is achieved by the use of a steel catenary support wire to which the LHDC is affixed. LHDC and Catenary Wire Support

Fire Safety Prevention for Non-Mining Conveyor Systems

27/01/2016  The majority of industrial fires which begin on or around conveyor systems occur as a result of ignited coal dust in underground mining operations. But while the fire risks of the fossil fuel industry are well-known and documented, fires involving belt conveyors or other material handling systems are far from restricted to this sphere of production. Conveyor systems are common in a

Fire Fighting / Protection for Coal Conveyors?

27/04/2010  there is no one answer for your question as fire and explosion prevention are a hand in glove item and are not separable when it comes to coal. many mines have sprinkler systems along the main line inbys and outbys where conveyors are located. many mines and conveyors simply have fire extinguishers at transfer points.

On the basis of the analysis carried out in order to protect the inclined coal conveyor against fires, we designed a fire detection, alarm and extinguishing control system (FDAECS). The protection extends along the inclined coal conveyors system, within which we used linear thermal detectors (sensor cables) and manual call points. Furthermore, we applied fixed extinguishing devices in the form ...

Fire Suppression systems are the first line of defense after a conveyor belt fire has started in an underground coal mine. Between 2000 and 2009, twenty-five fires in underground coal mines were caused by friction of conveyor belts against pulleys, drives, rollers, idlers, and bearings (MSHA). These fires were often not detected for
