Fire protection made in germany
In pneumatischen Transporteinrichtungen und mechanischen Förderanlagen, in denen brennbare Materialien transportiert werden, kommt es durch Funkenflug immer wieder zu Bränden und Filterexplosionen. Der Funkenflug wird in der Regel durch die eingesetzten Maschinen oder durch Materialverunreinigungen erzeugt.
Produktionsausfälle, hohe Sachschäden und die Gefährdung von Menschenleben sind die Folge. Um dieses Risiko auszuschließen, müssen Absauganlagen auf Funkenflug überwacht und durch Funkenlöschanlagen gesichert werden.
Für umfassenden Versicherungsschutz sind Funkenlöschanlagen nach den Richtlinien des Verbandes der Sachversicherer (VdS 2106) inzwischen meist Voraussetzung.
Heat sources can unknowingly arise in many production processes in the machining and processing industry. These heat sources can be classified as hot particles, glowing particles or sparks, depending on the infrared light they emit. Depending on the process, these ignition potentials can be caused, for example, by friction on slow and fast rotating processing machines, tool breakage or material contamination. These ignition potentials can reach downstream plant areas through mechanical or pneumatic conveyor systems and lead to devastating fires or explosions. The consequence is obvious: a state of limbo in which companies often have an uncertain future. Production interruptions, long reconstruction times and a lot of communication with the property insurer sometimes lead to a long absence from the market. As a result, around ¾ of companies become insolvent and some disappear from the market altogether.
T&B spark extinguishing systems prevent this scenario by reliably detecting ignition potentials such as hot particles, smouldering particles and sparks and, depending on the application process, safely extinguishing them, discharging them or preventing them from being conveyed further by means of gate valves.
Advantages of the T&B spark extinguishing system
- Detection of all critical ignition potentials such as sparks, glowing and hot particles
- Unique selection of different infrared sensors
- Fine extinguishing water mist does not interfere with the process
- In addition to water extinguishing, gas, valves and diverters are also available
- Preventive measure to prevent fires and explosions
- Generally no interruption to operations
- Can be retrofitted at any time without any effort thanks to the globally unique mounting system for components
The fully automatic spark extinguishing systems from T&B basically consist of spark detectors, an automatic extinguishing system and the centerpiece, a spark detection control panel. The water supply can be provided by an existing sprinkler system or by a T&B pressure booster system. If an ignition potential is detected by the spark detector, the automatic extinguishing system is activated within milliseconds via the spark detection control panel and a fine water mist is sprayed into the extraction line for 3 seconds. If sparks continue to fly, a second alarm threshold is reached, which should lead to the process being switched off.
The selection of the right spark detector is particularly important. Depending on the process, different ignition potentials such as sparks, glowing and/or hot particles can occur. All these particles imitate in a different infrared wavelength range. To ensure reliable detection of the aforementioned ignition potentials, it is therefore essential to select the right spark detector.
T&B has different types of high-performance spark detectors in which different sensor elements are used. This allows T&B to offer you the most reliable spark detector with the greatest sensitivity depending on the application process.
In some applications, water cannot be used as an extinguishing medium due to the process characteristics. In these cases, T&B offers special gate valves and diverters to eliminate the ignition potential. Combinations with gas extinguishing systems for object protection or pipe fire extinguishing are also possible.
Worth knowing
Pipe fires are an often underestimated risk in extraction systems. Particularly in processes containing oil and grease or if the extraction pipes are not cleaned properly, deposits can quickly build up in the pipes, which represent an enormous fire load. If sparks or glowing particles are introduced into the extraction line, the deposits can easily ignite. Due to the permanent supply of oxygen, swelling fires in extraction ducts spread rapidly. Firefighting from outside the pipe by firefighters is virtually impossible. T&B pipe fire extinguishing systems therefore offer you significant safety.
When using spark extinguishing systems, particular care must be taken to ensure that they only correspond to the state of the art and thus offer the greatest possible protection if the effectiveness of the system has been verified by an independent body. This must be done in comprehensible and reproducible fire tests in accordance with European-wide standards.
To maintain insurance cover, it is therefore important to ensure that planning and installation are carried out in accordance with the VdS regulations VdS 2106. The use of a VdS-approved spark extinguishing system installed by a VdS-approved installer not only offers the greatest possible process reliability, but also prevents the loss of insurance cover.
