Spark extinguishing system

During some specific industrial processes, sparks and embers can be generated. These can be transported by air currents along ducting or by conveyor belts, and be deposited in the filtration unit, hopper or silo. The transported material can start smouldering, which can lead to a fire or a destructive explosion.

In order to minimise the risk of fire – to protect equipment and persons and to reduce any downtime resulting from a fire, RSBP offers a tried and tested spark extinguishing system for preventative protection from fire.

Advantages:

  • Great effectiveness and short reaction time of system
  • Possibility of fitting on short tubes too
  • Flexible and modular system
  • Ease of installation
  • The design of the nozzles prevents clogging
  • Automatic checking that detectors are not fouled
  • Automatic restoration of operation
  • Suitable for outdoor applications

Risk – Sparks and burning particles resulting from:

  • Friction
  • Static charges
  • Addition of foreign particles
  • Spontaneous combustion

FUNCTION OF THE SYSTEM

The basis of the spark extinguishing system consists of highly sensitive detectors reacting in a few milliseconds to the presence of sparks in conveyor systems. If sparks or a fire appear, the control unit immediately receives an impulse from the detector, and on the basis of electronic analysis it activates the quick-opening valve releasing pressurised water within a few thousands of a second. The extinguishing nozzle in the conveyor system creates a conical mist of extinguishing agent, and the undesirable sparks or burning particles are extinguished. At the end of system activation and the effective elimination of the danger, the system automatically reverts to the standby state.
