RECYCLING Photo: Fagus Metal is recovered from residues in four melting furnaces. Photos: Siegfried Jacob Metallwerke GmbH & Co. KG Recycling – certainly safely! The GreCon spark extinguishing system sees to a safe production at Siegfried Jacob Metal Works by Denis Sauerwald, Alfeld Recycling instead of scrapping With the recycling of basic materials becoming more and more important, the demands on recycling companies are also increasing. Coping with continuously growing quantities requires a high availability of the production facilities. To ensure the highest possible availability, it is necessary to protect the facilities at risk against loss of production caused by fire. Fire risks are lurking in numerous phases of recycling processes. Foreign objects, process heat or machine parts can cause sparks, glowing embers or overheating which may lead to serious fires or explosions in shredders, belt conveyors or extraction systems. In the field of recycling, Siegfried Jacob Metal Works have been specialized in the recovery of metals for more than six decades. The company, located in Ennepetal, Germany, is known as a reliable supplier of high-quality secondary raw materials from aluminium to zinc. Founded as a scrap metal merchant in 1953, the company developed into one of the major metal recycling companies in Europe in the past 60 years. Today, several thousand tons of metal are recovered per year at 10 sites with about 1,000 employees. The site in Ennepetal, Germany, produces several thousand tons of secondary raw materials in 33 halls. Metal recycling – a hot matter The conditioning processes reach from classic sorting via pyrometallurgy up to hydrometallurgy. Especially in pyrometallurgical processes, there is a permanent risk of spark flight. Pyrometallurgical recycling simplified means that scrap metal and other metallic residues are melted at high temperatures in a furnace and processed to customer-specific alloys. Siegfried Jacob Metal Works produce up to 10,000 tons of metal out of scrap metal per year in four melting furnaces, having a capacity of several tons each. There is a permanent risk that sparks or glowing particles reach the filters via the extraction system where they would meet an explosive dust concentration and can cause devastating fires or explosions. Siegfried Jacob Metal Works want to reliably prevent such damaging events. 30
An automatic extinguishing device is mounted directly before the filter and eliminates risks of fire before they can cause damage. Highly sensitive GreCon spark detectors, type FM 1/8, are mounted on the exhaust duct and detect sparks and glowing particles. Protected against sparks for many years Siegfried Jacob Metal Works already protected their filters with automatic spark detection and extinguishment in 2001. “The spark extinguishing system makes us feel safe that no sparks can reach the filters”, says Dr. Joachim Lüning, Factory Manager. The GreCon spark extinguishing system has been in operation for 15 years. The recycling company has the system, that is working very reliably, serviced on a regular basis by the GreCon service team – being 70 strong. Maintenance comprises numerous function tests of the system, the cleaning of spark detectors and extinguishing devices as well as software updates of the control console, if necessary. Prepared for the future Siegfried Jacob Metal Works intend to continue their growth strategy. A modern wind energy plant is planned for power supply. Future expansions of the production capacity require new extraction systems. In preparation of this, the control console of the spark extinguishing system was updated to the latest generation. The new control console (type CC 5016) is easier to operate and provides a graded alarm function thanks to programmable alarm thresholds as well as the option for possible extensions.
