PYROTECHNICAL IGNITION SYSTEMS (PTIS)

The demand from industry to transition away from continuous flare pilots has resulted in the development of the PTIS offering advanced flare ignition using a pyrotechnical pellet launched through a guide pipe to produce a highly reliable spark shower ignition at the flare tip.

pyrotechnical ignition systems (ptis)

The demand from industry to transition away from continuous flare pilots has resulted in the development of the PTIS offering advanced flare ignition using a pyrotechnical pellet launched through a guide pipe to produce a highly reliable spark shower ignition at the flare tip. The PTIS provides 99.8% reliable, safe and on-demand ignition, regardless of weather conditions, thus minimising pollutant emissions by eliminating the need for continuous pilots and limiting the release of unignited flare gas to atmosphere.


Low Pressure Pyrotechnical Ignition Systems

  • Type
    Low Pressure Pyrotechnical Ignition System
    Pyrotechnical ignition system using a low-pressure air supply system to activate and launch a pyrotechnical ignition pellet through a pellet tube to a pellet collector adjacent to the flare tip. Upon arrival at the pellet collector, the pellet releases thousands of zirconium sparks in a large mist, covering the flare tip, and igniting the flare gas.
  • Applications
    Elevated Flare Tips / Ground Flares / Burn Pits
  • Function
    Pyrotechnical Ignition
  • Pellet
    20mm LP Flare Ignition Pellet (Nammo LP 2000)
