The ignition system will deliver a cascade of sparks over the flare tip to ignite the flare gas and can be used under any weather or operating conditions. With no electronic equipment or movable parts located within the high heat radiation areas, the system is reliable and easy to maintain. Pilot burners are not necessary, and there is no heat sensitive equipment, such as cables, instrumentation and electrodes, on the flare deck.
The complete system consists of a cabinet installed at an easy accessible area, a guide pipe installed from the cabinet to the flare tip, and a fragment collector installed near the flare tip where the guide pipe ends.

BALLISTIC IGNITION CABINET
The flare gas ignition cabinet is installed at a safe distance from the flare stack, and a guide pipe leads to the flare tip. The system is suitable for all flare tips and may ignite several flares on one flare deck. It combines high reliability and availability throughout the lifetime of the facility. It features low maintenance requirements and is easily retrofitted into existing installations. It does not need any pilot burners, and has no equipment on the flare deck that is sensitive to heat, such as cables, instrumentation, or electrodes.
The ignition pellet is launched through a guide pipe to the flare tower. The pellet bursts and generates a shower of sparks when exiting the guide pipe. The resulting shower of sparks is directed towards the flare tip and instantly ignites the gas cloud. The system is designed to operate for flare towers up to 2000 meters from the launching unit. The pellets are safe to handle and are stored in the launching unit.
The guide pipe is a 25mm tube connected to couplings designed to have the right amount of space for ease of passage of the ballistic pellet. It has been successfully tested to lengths up to 1000 metres, which can locate the cabinet in an easy accessible and safe area and is available in 316SS as well as 6MO.
The fragment collector basically collects and stores the converted pellets after the launch. Supplied in Incolloy 800HT, it is also designed to withstand high temperatures. The Collector is capable to contain up to 2000 pellets, therefore allowing up to 2000 ignitions between maintenance and emptying.
