- A spark extinguishing system (also known as spark detection and extinguishing system") is used for preventive fire protection. A spark extinguishing system can detect and eliminate ignition sources before a fire or dust explosion occurs. Systems for grinding, chopping, drying, cooling and pressing materials including their pneumatic or mechanical transport and extraction systems and facilities for separation or storage purposes, also dust collectors, filters, cyclones, silos, and hoppers are especially at risk. In industrial production, raw materials are reduced in size to a high degree. Therefore, pneumatic or mechanical conveying paths are a principal component of production facilities. However, not only the "planned" dusts and bulk goods are transported via this connection. Sparks or smouldering particles may also be generated in processing machines or dryers and are therefore a significant fire and explosion hazard for downstream system parts including filters and silos. A fire or a dust explosion is caused if three conditions are met: combustible dusts, air (oxygen) and an ignition source, (explosions also require confinement and material disbursement into the air). If these conditions occur, a fire may occur. The removal of one of these conditions will greatly reduce the risk of a fire or explosion. Since the combustible dust cannot be eliminated, there is the possibility to use inert gases or to eliminate ignition sources. Spark extinguishing systems are established as preventive fire and explosion protection systems in the industry and craft. Nowadays, many industries could not be operated economically without spark extinguishing systems. Technically they are the only preventive fire protection. Other measures, such as explosion suppression or sprinkler systems, are called reactive measures. (en)
