The ESI ignition system provides rapid, reliable ignition and more importantly, instantaneous re-ignition if the pilot should ever lose its flame. This ignition system uses a fuel gas line much like other ignition systems, however, instead of a flame front generator it utilizes the “Excitor” which produces a high voltage spark directly in the pilot nozzle. This cutting edge innovation originated in the aerospace industry.
Flame front generators are effective, time proven ignition systems which have been widely used in flaring applications for decades. The inherent reliability, rugged construction, ease of operation, and its economic advantages have allowed the flame front generator (FFG) to remain one of the most popular forms of pilot ignition in the industry. The FFG is easily adaptable to any pilot system which incorporates an ignition tube and may be installed up to 1 mile (1600m) from the base of the flare stack. Both Automatic and manual modes are available.
