FFG Flame Front Generators
Flame Front Generators are a traditional method of lighting flare pilots. An FFG panel mixes plant air and fuel gas into an ignition chamber. A spark plug ignites the mixture. The "flame front" travels through a 1" pipe to the flare pilot and ignites the pilot gas.
Although this technology has been around for many years, there are challenges associated with these systems. Fine tune adjustments of the air / fuel ratio have to be made from time-to-time to produce a reliable spark to generate the flame front. In addition, water condensation can build up over time in the FFG pipe which will extinguish the flame front.
We strongly recommend the Hero HES spark ignited pilot for most applications. The advantages of the Hero HES Pilots is that they can be installed on a state-of-the-art pilot retraction system (up to 200ft) which will allow the pilots to be raised and lowered from grade level.
However, for certain applications, we recommend a flame front generator ignition system. The FFG is a good choice if the flare meets some of the following criteria:
- Fixed spark ignited pilots with limited access and no retraction system.
- Flare stacks taller than 200 ft.
- Existing flare and pilots are designed for FFG ignition.
- Offshore platforms. Corrosive and salt water environments need special materials.
For the vast majority of production field and gas plant flares, the HERO HES Pilot is the perfect choice!
