The general rule in fire protection systems for conveyors is to locate Ember Detector(s) upstream from a change in direction (transfer to another conveyor) or a dust producing process or storage point. Hence, once the ember is detected, it can be extinguished before it enters the next process where it can cause a potential explosion.
systems to extinguish conveyor belt fires (Rowland, 2009). Four different fire suppression systems were tested in the NIOSH Fire Suppression Facility (FSF); water sprinkler, deluge water spray, and two different types of dry chemical fire suppression systems. The largescale fire tests were conducted using fireresistant SBR belt.
Fire in the coal conveyor will be detected by the linear heat sensing cables and infrared ember detectors which shall provide signal for electrical actuation for deluge valve. MVWS system spray nozzles shall be provided in the centre of the conveyor belt for top conveyors, and on either side of the conveyor .
Hydraulic systems should only use listed fireretardant hydraulic fluids. Automatic sprinkler or water spray systems should be employed for fire protection of coal handling structures that are critical to power generation where coal or coal dust is likely to be accumulated. Fire protection to pulverizers. Design shall be in accordance with NFPA 85.
NFPA 15 Standard for Water Spray Fixed Systems for Fire Protection. – Open nozzles shall be located to direct water spray onto the surfaces to extinguish fire in hydraulic oil, the belt, the contents on the belt, or the drive unit.
pressure versions for use at coal conveyor systems, steam turbines and cable channels as well as in offi ce and administrative areas. Deluge systems: Fast, with overall coverage Minimax deluge systems are suitable for use in areas where a fi re can spread particularly quickly, in oil tanks, on coal conveyor systems and transformers.

Conveyor system closures. Various production and logistics processes call for the most diverse types of conveyor systems. If these conveyor lines pass through fireretardant or fireresistant walls or ceilings, the openings required for this purpose must be provided with fire protection closures to prevent the spread of fire through the conveyor system or the goods conveyed.
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.

Fireprotection guidelines for handling and storing PRB coal Most plants that burn PRB coal were not designed to deal with the fuel''s propensity to ignite in bunkers, silos, and hoppers. Recognizing this, the PRB Coal Users'' Group has come up with a set of recommended practices for safely preventing, detecting, and extinguishing coal fires at
Undoubtedly, the primary function of any fire detection system is safety, especially in environments accommodating vulnerable individuals or requiring largescale evacuation procedures. Starfire Systems understands the vital importance of these circumstances and is fully prepared to offer protection of the highest quality and effectiveness.
