NAO has supplied flamefront and electronic ignitors for over 75 years and has a wide
range of applications and experiences.... from offshore subsea systems, refineries,
gas plant pit flares, steel mills and chemical plants.

Flamefront Ignition Panel with Manual Pilot Gas Control -- flamefront can travel 1 mile through 1" diameter pipeFlamefront Ignitor for Offshore -- Boom or Bridge Flare (NOT SUBSEA due to condensate build up)Remote Subsea Ignitor -- High Energy Electronic Spark -- Subsea cable carries pilot gas, 24VDC and TC mv signal from thermocouple


Much of the work involved testing, proving and improving the ignitor designs to meet
specific customer needs or problems, such as, dirt and dust built up on pilots/ignitors
for coke ovens in steel mills.  Another example is the problem with condensate in the
flamefront pipes for subsea offshore flares.
