What is a Flame Front Generator FFG?
A flame front generator (FFG) is a fireball ignition system that produces a precisely metered, travelling flame front inside a fuel-air mixture, propagating it through a transfer line to ignite a flare pilot located up to 100+ meters away.
How it works
A metered fuel-air mixture ignites inside a chamber and propagates as a flame front through a transfer tube to the pilot, covering distance that a direct spark could not reliably bridge.
A controlled fuel-air mixture is metered into an ignition chamber, with the ratio set to sustain stable flame front propagation across the full transfer line.
A spark or pilot source ignites the mixture inside the chamber.
The flame front travels through a dedicated transfer tube at high velocity, carrying enough energy to ignite the pilot despite distance, elevation change, or wind exposure.
Automated systems repeat the cycle on a timed or demand basis, while manual systems are triggered on operator command.

Frequently Asked Questions
How do operators manage odour and harmful gases from biogas plants?
Odour mainly comes from hydrogen sulfide (H₂S) and volatile organic compounds. Biological scrubbers, activated carbon filters, and advanced membrane systems can remove >98% of these impurities, ensuring both compliance and community acceptance.
Why are flares considered critical in biogas plants?
Flares aren’t just backup devices — they are essential safety systems. In case of excess gas, pressure build-up, or equipment failure, a flare safely combusts methane and other gases, preventing leaks, explosions, and environmental damage.
