WHY CHOOSE A SPARK DETECTION AND EXTINGUISHING SYSTEM?
Industrial fires and dust explosions have been constant threats within industries worldwide. Not only do these incidents result in injuries and even death, they also lead to severe property damage and interruptions to production.
Consequently, millions of dollars are lost annually. It has become more important than ever to focus on measures that pre-act before such a fires or dust explosions even occur. One such notable preventive measure is the adoption
of an advanced spark detection and extinguishing system, like that of GreCon, ranked as one of the best in the business.
PRINCIPLE OF THE SPARK DETECTION AND EXTINGUISHING SYSTEM
The GreCon system fundamentally is a particle detection mechanism. The system identifies dangerous, potential ignition sources, e.g. sparks or hot black particles, within process flows and extinguishes them within milliseconds.
All of this occurs before these particles can initiate a fire or dust explosion.
The heart of the system is the control unit, which has two crucial functions: detection and immediate, automatic extinguishing. By designing the system this way, GreCon has essentially established a preventive mechanism that proactively eliminates ignition sources. Consequently, this design has undoubtedly positioned the GreCon Spark detection and extinguishing system as a 'preventive system.'
StuvEx International plays a crucial role in further fortifying safety measures within industries by engineering, installing, and maintaining the GreCon Spark detection and extinguishing system We recommend thoughtful and
customer-specific solutions that not only reduce the frequency of false alarms, but also contribute to uninterrupted industrial production.
RECOGNIZE AND CONTROL IGNITION SOURCES
Sparks or hot particles are known ignition sources. Generally, the human eye can detect these particles only when they emit light - usually at temperatures of about 700°C or more.
All particles below this temperature are perceived by human eyes as ‘black’ hot particles. Most combustible materials can ignite at much lower temperatures than 700°C.
Several fire problems within industries arise from the issue that friction generates hot black particles that are not easily visible. Other potential dangerous scenarios include presence of
metal pieces within the process, excessively dry product or material build-up.
Certain types of process equipment, such as mills, fans, dryers, woodworking machinery and mechanical conveyors… have been known to generate sparks or hot black particles.
Consequently, these devices need to be monitored consistently and maintained regularly.
The GreCon system can be effectively applied across multiple processing stages, including:
INDUSTRIES EXPOSED TO FIRE AND EXPLOSION HAZARDS
- Wood industry: e.g. furniture, OSB, MDF, chipboard, multiplex and woodworking
- Recycling industry: e.g. metal, paper, plastics, and rubber
- Heat and power plants: e.g. solid biofuels (like pellets)
- Food and feed industry: e.g. flour, sugar, coffee, cacao
- Chemical industry: e.g. raw materials, chemicals, fertilizers, dyes, plastics, pharmaceuticals, cleaning agents, cosmetics
- Pulp and paper: e.g. tissue, hygiene (like diaper), packaging
- Textile industry: e.g. linen, wool

SPARK DETECTION
An essential feature of any spark detection and extinguishing system is its detection functionality. The goal is to locate potential danger quickly while minimising false alarms.
False alarms can cause undesirable disruptions, including the unnecessary injection of water into the process. By selecting the appropriate detector for the specific application,
sensitive to daylight or not, a GreCon Spark detection and extinguishing system offers premium detection capabilities.
- GreCon FM 3/8: designed for high-temperature applications.
- GreCon DLD 1/9: ensures optimal detection performance in any environment.
- Thermo Detector GreCon TM 1/9: early detection of dangerous temperature increases.
- Thermo Detector GreCon TM 3/9 plus: protects against fire risks caused by overheating machinery.
- Flame Detector GreCon Talentum: detects starting fires of organic dusts with a high visual range and minimal false alarms.
- Hotspot Detector GreCon IR: identifies smouldering fires and open flames
The ART OF EXTINGUISHING
The process industries often handle a substantial flow of materials, demanding a powerful extinguishing method to fully penetrate these flows.
Although water is the most common extinguishing agent, GreCon system also employs mechanical diversion or isolation for instances where water is inappropriate.
In case of WATER EXTINGUISHING to prevent fires and dust explosions, ensure that extinguishing happens in a sufficiently wide angle in order to secure full coverage of the
entire cross-section of a duct or chute. The extinguishing force should penetrate even large, compact material flows. Moreover, the response time of the extinguishing needs
to occur within milliseconds after detection. These objectives are met by the:
- Intelligent Extinguishing Module (IEM): extinguishes sparks and monitors wear for early maintenance alerts.
- Extinguishing Devices (LS and UHS): perform a swift spark extinguishing action using ultra-high-speed technology.
MECHANICAL DIVERSION OR ISOLATION
GreCon also proposes a variety of isolation or diversion methods for ignition sources when water use is unsuitable. GreCon’s ultra-fast isolation and diverter valves come in various types and sizes.
Note that CO2 gas is frequently used alongside isolation valves to inert the isolated process volume.
