The pneumatic conveying of combustible dusts carries an inherent risk for dust fires and explosions in many applications. 

Drying and hammermilling operations can often cause sparks, which are typically the ignition source for fires and explosions in dust collectors and air filtration equipment. 

The FLAMEX Spark Detection and Extinguishing System is the most cost effective solution for the prevention of these baghouse fires and explosions.  It can identify and extinguish a spark in a pneumatic duct within a fraction of a second, preventing the spark from entering filtration units and storage bins where violent explosions and fires can occur. 

 

The system utilizes infrared detectors to sense burning embers or sparks transported through ductwork leading to a dust collector. Upon sensing a spark, it triggers an extinguishing device located downstream from the detectors, which produces a water spray to effectively extinguish the burning material. The system reacts in a fraction of a second, and the extinguishing device sprays just long enough to ensure suppression so that typically no downtime or clean-up is required. In applications where water is not an acceptable extinguishing agent, the FLAMEX system can also be programmed to activate other extinguishing agents, abort gates, diverter valves, or shut down equipment. 

FLAMEX is the first and original Spark Detection and Extinguishing System in North America. Currently in its fifth generation of development, the FLAMEX system has been successfully used in number of pellet manufacturing facilities across the U.S. and Canada.
